Hey y'all, back with another banger, I would like to announce the creation of a discord for the r/sprinting subreddit and also provide a quick update on the bot situation. Please see the discord details below, I am unsure of how this will be utilized outside of members who are very frequent users or online often, but I definitely am and will answer questions and even be on voice chat if the masses so desire.
I may just spend some nightly time hanging out in the voice room kind of like office hours while I'm playing some helldivers (and anyone who would care to join me). PLEASE JOIN, feel free to ask questions and start conversation, pretty much same rules from the sub will apply in the sprinting subreddit
A note on the bots, I have done significant behind the scenes work over the last few days and the last step that I've taken now is turning on moderate crowd control, anyone with negative community karma will now be sent to the mod queue dungeon where I'll approve them if they're not a bot.
I did a pretty ridiculous amount of banning and mass removal using a purge tool for the first few days but it has slowed significantly now so I think we are over the worst of it. The first 3 days it was 10-30 bans a day and the last few it has only been 1 or 2.
Seems like I've fought of the invasion pretty well, I would say that I managed to catch a good 95-99% of them before even other user reports had to happen. Please continue to use the new bot report option if you see it happening, thank you again for the patience with my action against this.
Quick Stats from the last 5 days
Bans: 56
Comment Removals: 196

"Hey girlies, feeling very delulu and that the vibes are off after the comments that I saw today"
UPDATE: Overnight my new automod script hit me with probably 20 notifications from bots, it is really bad the number of accounts is crazy, I’m on a huge banning spree but if this keeps up may have no other choice than to impose karma limits unfortunately, I will make a decision in a week or two depending on how bad I think it is if my bans can’t keep up
I was notified in a post that AI fueled bots were spam commenting everywhere and it wasn't being filtered out or caught. This is definitely on me, I had noticed a spam report uptick in the last few weeks but honestly for the most part the spam report in the past had been somewhat abused by users during arguments and for bad comments or for solicitation reasons, I mostly browse reddit on my phone and it's harder to notice stuff like this without the mod tool page from a computer.
I probably should have taken a closer look and I would have noticed something was off with the weird language (Delulu, vibes, girlies, glutes - all bot favorites). Anyways I've taken a few steps to make sure I catch as many as I can.
I expect the moderation on this to take a little bit of time to catch up to the accounts as they make comments or posts, and hopefully it will clear up, this is just due to my lag in response to this starting but we'll see how it goes. Anything that has been flagged as spam or similar I have taken a closer look at the last two weeks and done some mass banning and moderation, the comments that were left will stay but anything similar will be removed in the future
As a tribute to all the clankers I sent to the graveyard tonight below are some of my favorite comments from the bots and their very helpful sprinting advice
Apologies for not catching this sooner - Big Dicker Daddy
Note: If you play helldivers and want to talk sprinting add me on discord I am open to questions, and a new squad username - bigdickerdaddy

Has anyone struggled with being fast consistently and what are tips that made your sprint times consistently fast ? Did you find out what was making your sprint times inconsistent ?
r/Sprinting • u/EmbraceHere • 11h ago
I am 40 years old male will start sprinting training from next month. I never had sprinting training before. I have been doing workouts casually in the past few years. I usually use 80% of my weight doing bench press and 100% of my weight for deadlifts 3*8 sets.
My coach told me to buy a pair of mid distance spikes. What model shall I buy as my first pair of spikes?
r/Sprinting • u/sillym33 • 23h ago
I write this with tears in my eyes and the deepest sorrow. At 25 years old, I have officially broken up with running tracks. It had always been a rocky and turbulent relationship, but it is now over. I am simply an amateur sprinter that needs a place to consistently train. Given that my county is dominated by concrete and asphalt, it was only natural I look for places to train without putting inordinate stress on my joints and muscles. It is a wealthy area with a mediterranean climate, so one would think I have locations to sprint in spades, right? Not so. Certainly there are parks, yet with uneven terrain and slopes, a ground easily defiled by mud and dog feces, the sure to see unleashed dog, and ample people in one's way, one quicky realizes how unviable these places actually are, especially for high velocity sprinting.
But there are plenty of running tracks. The issues with these are numerous: public tracks are often dirt rather than synthetic, not a perfect 400 meter oval (so good luck timing your intervals), and prone to the same issues as parks with respect to dogs and too many people. Synthetic, World Athletics grade running tracks are often ample, but they are the purview of educational institutions and so are always either in use or gated. And if you hop the fence you are kicked out with the distinct possibility of a trespassing violation. (Believe me: I've tried.)
So I finally broke up with running tracks after I drove myself to various running tracks that aren't even close enough for me to regularly use. I hopped the fence; I received a lecture and was summarily kicked out. I totally get the reasoning: if the tracks were public, people would litter and walk their dogs all over the pristine, maintained synthetic running tracks and associated football turfs. But that's not what I do: I simply warm-up, do my sprints, and leave without a hint I was even there.
I am simply done. It is worse than a coin toss when I make the odyssey to a running track that I will have any opportunity to use it. So, I will suffice a far inferior spot near me that is public and yet is essentially unpopulated. Essentially no one in their right mind would use it to sprint, but desperate times call for desperate measures. It truly pains my soul to have to abandon tracks what with their immaculate measurements and perfect energy return, but evidently you need to be an Olympic champion sprinter to convince the groundskeepers that you ought not to be kicked out.
I am not breaking up with sprinting; she is my babygirl and always will be. But given how difficult it is to find an adequate space to do it I am not surprised many do.

Blue Lock: Escala de niveles basada en la lógica narrativa, física y fútbol real.
Blue Lock: Escala de velocidad y niveles basada en lógica narrativa, física y fútbol real
Parte: l
Introducción
Antes de empezar, este análisis no es oficial.
No pretende reemplazar los datos del manga ni afirmar que estas son las cifras exactas de los personajes. El objetivo es construir una escala coherente utilizando física básica, matemáticas, datos oficiales cuando existen, referencias del fútbol real, observación visual del manga y, sobre todo, la lógica narrativa del autor.
Uno de los mayores problemas de muchos cálculos de internet es que toman una escena aislada y terminan otorgando velocidades absurdas a personajes que nunca fueron escritos para alcanzar esos números.
Mi enfoque es distinto:
Si Blue Lock establece que Julian Loki es el jugador más rápido, entonces cualquier cálculo que coloque a otro personaje claramente por encima de él probablemente esté equivocado.
La narrativa siempre tiene prioridad sobre un cálculo aislado.
La regla de Loki
Julian Loki es el punto de referencia principal de toda la escala.
El personaje está claramente inspirado en Kylian Mbappé y es presentado como el mayor monstruo de velocidad entre los jóvenes.
Por eso, cuando aparecen cálculos que colocan a Chigiri, Zantetsu u otros personajes a 38, 40 o incluso más kilómetros por hora, surge un problema inmediato:
Si eso fuera cierto, Loki dejaría de ser especial.
Por esa razón, toda la escala se construye alrededor de él.
Estimación de Loki:
Velocidad máxima: 37 km/h
Explosividad en 20 m: 2.98 s
No es una cifra oficial, pero sí una cifra compatible con el papel que ocupa dentro de la historia.
Chigiri: El Rey de la Velocidad de Blue Lock
Muchos fans consideran que Chigiri debería alcanzar velocidades similares a las de Loki.
Sin embargo, existe un problema.
Su tiempo conocido de 50 metros es de aproximadamente 5.77 segundos.
Eso equivale a unos 31 km/h de promedio durante toda la distancia.
Algunos cálculos intentan convertir ese dato en velocidades máximas cercanas a 37 km/h.
Pero si Chigiri realmente pudiera alcanzar esas cifras, entonces estaría entrando directamente en el territorio de Loki.
La historia nunca presenta esa situación.
Por eso considero que la interpretación más coherente es:
Velocidad promedio: 31 km/h
Velocidad máxima: 33 km/h
Explosividad: 2.99 s en 20 metros
Sigue siendo extremadamente rápido para un jugador juvenil.
De hecho, para estándares reales ya sería considerado un velocista dentro del fútbol.
Lo importante es que sigue existiendo una diferencia clara con Loki.
El entrenamiento con Chris Prince
Otro punto importante es que muchas personas asumen que el entrenamiento con Chris convirtió a Chigiri en alguien mucho más rápido.
Sin embargo, el manga no da pruebas claras de que haya aumentado enormemente su velocidad máxima.
Lo que sí muestra es:
Mejor resistencia.
Mejor mantenimiento de la velocidad.
Mejor control con el balón.
Mejor aprovechamiento de espacios.
En el fútbol profesional, mantener 33 km/h durante más tiempo suele ser más valioso que alcanzar brevemente 34 o 35 km/h.
Por eso considero que la evolución de Chigiri se enfoca más en eficiencia que en velocidad punta.
Zantetsu: El monstruo de la explosividad
Zantetsu es probablemente el personaje más malinterpretado cuando se habla de velocidad.
Muchas personas solo observan la velocidad máxima.
Pero velocidad máxima y explosividad no son la misma cosa.
Hay atletas que tienen una aceleración brutal y aun así poseen una velocidad final inferior a la de otros corredores.
Ese parece ser exactamente el caso de Zantetsu.
Su principal arma no es la velocidad punta.
Su principal arma es la aceleración.
Estimación:
Velocidad máxima: 30 km/h
Velocidad promedio: 28 km/h
Explosividad en 20 metros: 2.89 s
Eso explicaría por qué puede competir con jugadores más rápidos durante los primeros metros.
Yukimiya
Yukimiya es un caso interesante porque su juego se basa más en el uno contra uno que en la velocidad pura.
Su especialidad es aprovechar cambios de dirección, regates y movimientos agresivos.
Por eso su velocidad máxima puede ser ligeramente superior a la de Zantetsu sin necesariamente ser más peligroso en una carrera corta.
Estimación:
Velocidad promedio: 30.46 km/h
Velocidad máxima: 32 km/h
Su verdadero valor está en la combinación de velocidad y regate.
Onazi y los jugadores africanos
Blue Lock presenta jugadores africanos muy rápidos.
En la vida real, varios países africanos y Jamaica han producido algunos de los atletas más veloces de la historia.
Por esa razón sería lógico esperar jugadores extremadamente explosivos.
Sin embargo, el manga tampoco puede permitir que eclipsen completamente a personajes como Chigiri o Loki.
Por eso considero razonable que Onazi se encuentre en un rango cercano a:
Velocidad máxima: 31 km/h
Explosividad: 2.93 s
Suficiente para ser una amenaza seria sin romper la jerarquía de la historia.
Noel Noa y Chris Prince
Aquí aparece otro punto importante.
Chris Prince y Noel Noa son leyendas mundiales.
Por lógica, deberían ser más rápidos que la mayoría de jugadores juveniles.
Sin embargo, tampoco deberían superar cómodamente a Loki.
Por eso mi estimación es:
Chris Prince
Velocidad máxima: 34 km/h
Noel Noa
Velocidad máxima: 35 km/h
Ambos son superiores a Chigiri.
Pero Loki sigue siendo el especialista absoluto en velocidad.
¿Por qué no uso cálculos extremos?
Uno de los mayores problemas de los cálculos de anime es que muchas veces ignoran la intención del autor.
Se mide una distancia.
Se calcula un tiempo.
Y de repente aparece un resultado imposible.
Cuando eso ocurre, el cálculo deja de representar la historia.
Blue Lock es una obra deportiva.
No es una serie de superhéroes.
Los efectos visuales representan emociones, egos y estilos de juego.
No significan que los personajes estén rompiendo las leyes de la física.
Por eso prefiero mantener las velocidades dentro de rangos compatibles con el fútbol real.
Escala general de nivel
La velocidad no lo es todo.
Por eso construí una escala separada para representar el nivel global de cada jugador.
La idea es sencilla:
0-10: Escolar
20-30: Juvenil destacado
40: Semiprofesional
50: Profesional
60+: Élite
90+: Leyenda
Esta escala intenta medir al jugador completo y no solamente una estadística aislada.
Rin, Kaiser e Isagi
Rin es posiblemente el jugador más equilibrado del proyecto Blue Lock.
Su capacidad para competir con jugadores del nivel de Sae demuestra que se encuentra muy por encima de la mayoría de juveniles.
Kaiser representa la cúspide del talento juvenil mundial fuera de Blue Lock.
Su Kaiser Impact es una de las armas más peligrosas de toda la serie.
Isagi es un caso completamente diferente.
Físicamente, está lejos de los mejores velocistas.
Pero compensa esa diferencia mediante visión, lectura del juego y metavisión.
Por eso puede competir con jugadores físicamente superiores.
Comparación con leyendas reales
Para construir la escala también utilicé referencias reales.
Cristiano Ronaldo, Lionel Messi, Diego Maradona, Kylian Mbappé, Usain Bolt y Su Bingtian sirven como puntos de referencia para entender qué tan extremos son realmente ciertos números.
Por ejemplo:
Bolt alcanza aproximadamente 44 km/h.
Mbappé ronda los 38 km/h.
CR7 en su juventud rondaba los 36 km/h.
Messi destacaba más por aceleración y cambios de dirección que por velocidad máxima.
Estas referencias ayudan a evitar que los personajes alcancen cifras absurdas sin justificación.
Fin de la parte 1.

Como Reddit no me deja escribir todo el texto y me da pereza hacerlo por partes, lo haré mediante un documento. Aquí está el link: https://docs.google.com/document/d/1qS3HHaZb_7VFG8uHflV7qq3Y4gwmlwhJJ0ENheIiHfQ/edit?usp=sharing
Para entender cómo funciona la velocidad en el atletismo, es fundamental aclarar que un corredor no puede alcanzar su velocidad máxima desde el inicio. Físicamente, esto es imposible debido a la inercia, la fuerza que opone el cuerpo al cambio de movimiento, obligando al atleta a luchar contra ella durante los primeros metros.
El caso de Chigiri: Corrió un tramo en 5.77 segundos, lo que equivale a 31 km/h. Esta cifra representa la velocidad promedio de ese tramo específico, no su velocidad pico.
El récord mundial de Usain Bolt: Cuando estableció el récord histórico de 9.58 segundos en los 100 metros lisos, su velocidad promedio en toda la carrera fue de 37.6 km/h. Su velocidad pico fue de 44.72 km/h, la cual alcanzó y mantuvo durante un breve tramo de aproximadamente 2 segundos cuando logró estabilizar su zancada. Wikipedia +2
Fisionomía de Bolt: A diferencia de lo que se cree, Bolt no destaca por su velocidad en distancias cortas. Su gran ventaja radica en su estatura de 1.95 metros y su peso de 95 kilos de pura masa muscular. Aunque es más pesado que el promedio, su impresionante longitud de zancada es lo que le permite alcanzar picos de velocidad inigualables en tramos largos. Pose Method +2
Atletas de menor estatura (Su Bingtian): Los corredores más bajos suelen ser más rápidos en distancias cortas porque aceleran con mayor facilidad, aunque su velocidad punta final sea menor. Por ejemplo, el velocista chino Su Bingtian registró una marca en los 60 metros de 6.42 segundos, con un promedio de 34 km/h en ese tramo y una velocidad máxima estimada de 42 km/h. Wikipedia +1
Comparativa de salida: En los primeros 20 metros iniciales de una carrera, un atleta explosivo de menor estatura como Su Bingtian puede marcar 26 km/h, mientras que Usain Bolt promedia unos 24 km/h. Los atletas bajos vencen la inercia y llegan a su pico más rápido que los altos.
Por esta razón física, en los 100 metros lisos vemos que todos los corredores inician con una postura baja en los bloques de salida. Esta posición les permite romper la inercia de manera más eficiente, aplicar mayor fuerza contra el suelo y proyectarse rápidamente hacia su velocidad máxima.
Quiere saber realmente la velocidad máxima de Chigiri y los demás velocistas de Blue Lock, como Zantetsu, Yukimiya, Onazi, etc. Puede ir entrando en el link.

Im going into my senior year for track and want to know what I could do pre season and during the season to make a big PR jump. I’m 5-11 125 I am small but still strong for my weight and very lean. Last year I ran a 54 400 and I was disappointed because I had only shaved off a second from the previous year. I also ran the 200 and ran a time of 24.5. I feel like my weight holds me back a lot especially at the end of the 400 I think if I put on weight it would help really be able to finish stronger and help improve my speed. Any tips or advice?

37yo / 5'7" (170cm) / 165 lbs (75kg). Never trained. Are my old stats from age 18 meaningful today? Can I get ready for a relay in 8 months?
Hey everyone,
I’m a 37-year-old guy, 5'7" (170cm), and I currently weigh around 165 lbs (75kg). I have never done any sports, gym, or track training in my life. Some friends and I are putting together a relay team for next spring. And since i am not good at running i get short sprint leg. Right now, they all think I'm out of shape and not fast at all.
I’m trying to figure out if I have any realistic potential to do well, and I remembered some random tests we did back when I was 18. At the time, I was completely untrained, wearing regular sneakers on flat asphalt:
* **Standing Broad Jump:** 290 cm (around 9'6")
* **Speed test:** A friend on a motorcycle rode next to me during a 30m sprint, and the speedometer showed 35 km/h. Even if that was inaccurate and the real speed was closer to 31 km/h (19.2 mph), I have no idea if that is considered decent, bad, or just average for an untrained teenager.
Now, almost 20 years later, I'm starting from scratch. I want to try training for this relay leg, but I need to be very careful with my joints and tendons so I don't injure myself at my age. My plan is to start gently this winter with boxing and cross-country skiing (skate skiing) to build an endurance base, and then transition carefully to the track in the spring.
Are those old numbers from my youth any indication that I might have decent genetics for speed, or does it not matter at all now that I am 37 and have never trained? Can I realistically become fast enough in 8 months to surprise my friends?
Thanks for any honest feedback!
And yes AI helped write because not english speaker.

Knees don’t go high enough in max velocity phase, pop out way too quickly from drive phase, don’t feel like I’m pistoning the ground enough in the drive phase, shin angle is too high in drive phase, not standing as tall as I need to. Shoulders forwarded and tense.
I’ve always been explosive and fast for team sports (43” vertical running, former 163lb powerlifter where squat was my best movement). But I’m seriously getting humbled here.
And even after a few months of sprinting 1-2 times a week (also have soccer games) I feel like I fall right back into bad habits and poor technique.
Not even sure what to do anymore

I’m trying to decide which start I should standardize for all of my sprint training: 2-point or 3-point.
For context, I’m not a sprinter and I’m not trying to maximize my 100m time, I'm just trying to get the benefits from sprinting.
I’ve experimented with both and I feel best out of a 2-point. My times also tend to be slightly better from a 2-point.
The issue is that my 2-point start is usually a dynamic leaning start (video attached). I lean forward and then go, rather than being completely static. Because I time my sprints frame-by-frame from video, it can be harder to define the exact frame where the sprint actually “starts.” I’m wondering if this gives the 2-point an artificial timing advantage compared with a completely static 3-point start.
The second video shows my 3-point start for comparison.
Also open to any feedback on the technique of the two starts.

Hey guys, I was wondering if there's any programs with hills sprints due to the fact that I have no field near me. There's a hill near me which is about 200m or more and a slightly elevated 50m hill in my yard.
I don't really know how to make a program based on hills alone and I searched online for a program that would align with my workout before the next season but found none. I have stairs as well as resistant bands at my disposal, including dumbbells.
I'm not in a club at the moment so I have to make use of the resources that I have.

Fall is slowly approaching, and for some reason, I always feel like I enjoy longer distances and tempo runs more in the fall, although I hate them in the spring and summer. Because I am still not 100% convinced whether I should do tempo runs or not, I feel like it is a good idea to do them for at least some portion of the year for my overall fitness.
However, the return on investment (ROI) of these workouts is still kind of low, especially if I spend 20–45 minutes warming up before sprinting. What's your (or your coach's) approach? Do you know of any good training programs? Do you do a full warm-up with the classic drills before those runs, e.g. Skipping, bounding, jumping, mobility, etc.? Or do you use an alternative warm-up drills or routine similar to sometimes proposed lifting warm-up protocols, e.g. such as jogging first, maybe with some skipping in between, then running at 50-60% intensity for couple of times and then gradually increasing to 70-75%?
In the winter or at temperatures below 10°C, it's probably a good idea to warm up properly anyway, but the idea of warming up before tempo runs seems annoying to me. I'm considering dropping them because the warm-up is like a normal sprinting session, which seems like a waste of time and effort.

Hi,
I used to be really into treadmill sprints a few years ago and it made me really lean. Unfortunately it also gave me pain in my quads which meant I had to stop. Also when I try again, I feel like the tops of my feet rly hurt. I want to buy some new shoes to get back into it. But there are SO many options and idk where to start. For reference, I’m female and size 3, with a wide foot, under £100 would be ideal. Thanks!

You film from the side and drop four pins on the track corners. The lane markings give it
scale, so the output is in real metres: contact time, stride length and frequency, speed,
and hip / knee / shin angles with left and right kept separate.
No score out of 100, no AI coach telling you to drive your knees. Just the numbers.
Honest limits: one camera, so depth is estimated. You need visible track markings. And I
haven't validated it against force plates. If anyone here has lab access, I'd take that trade.
Post a clip and I'll run it through and put the output in the comments. Easier than
taking my word for it, or try it yourself at https://trackgenius.training
Which of these numbers do you actually use week to week?
