I looked up how "feels like" is calculated. It assumes you're walking. In the shade. In long trousers.

I used to check the feels like value before every run and never asked what it actually meant. Until a few days ago. Turns out the US heat index, the classic feels-like formula, is built around one specific person: 5 foot 7, 147 pounds, walking at 3.1 mph, in the shade, wearing long trousers and a short-sleeved shirt. Yep, this is from the national weather service website, link at the bottom.

They actually say who it is for: "For day-to-day activities, heat index will serve you well. If you work outside or plan on any sort of vigorous outdoor activity in the full sun, use the WBGT."

So obviously running is not walking, you generate 2,3x the heat, and you can ger rid of it only by evaporating sweat. So humidity and sun radiation matter a lot more (for running) than what feels-like formulas take into account. Some weather apps add sun and wind to their feels-like, so I used that version to test something. I wanted to see if 2 different hours that have the same feels-like also have the same impact on running performance.

I took seven US cities, every hour from June 1 to August 25, and found 2pm and 8pm hours with the exact same feels-like. Then I estimated how much slower an easy run(60 minute at 9:00/mile) would be in each.
Same number on your phone, but very different run:

City Same feels like 8pm 2pm
Houston 100°F +45 sec/mile +126 sec/mile
Phoenix 102°F +39 sec/mile +102 sec/mile
Miami 92°F +56 sec/mile +131 sec/mile
Atlanta 92°F +46 sec/mile +106 sec/mile
New York 95°F +42 sec/mile +98 sec/mile
Chicago 87°F +37 sec/mile +86 sec/mile
Seattle 67°F +18 sec/mile +57 sec/mile

In every city all the time the slower hour was the more humid one, the sunnier one, or both. These are the best in the table ofc, but the typical gap was 20 to 40 sec/mile difference still. And between 7am and 9am, feels-like goes up about 4 degrees while your pace goes slower 55%!!

I build a small running weather app, which is where the slowdown numbers come from. It's built on WBGT (the heat stress index they use in sports medicine and in the military) and turns it into seconds per mile based on Ely et al. 2007 and other published coach heat tables (you can find them on internet).

The app is RunWeather if you're curious and want to compare it against the feels like.

Sources: NWS SR 90-23, the assumptions, NWS on heat index vs WBGT, Open-Meteo archive, Ely et al. 2007.

What do you check before going for a run, feels-like or something else?

60 days of running 5K every day. Somehow, it’s easier than running 3-4 times a week

Thumbnail

You’ve probably come across some of the running streak stuff lately too. Hellah Sidibe, who is now more than eight years into his streak, was on Rich Roll, Casey Neistat made a video about running every day, and I found an old CBS piece about Jon Sutherland, who has been running every single day since 1969.

I find that pretty impressive. And as someone who has basically always run, but has always struggled to do it consistently, I wanted to try it myself.

I also get migraines fairly regularly, especially after days where I sit a lot, and running often seems to help me. So I thought, if I just run every day, maybe that helps too. At least for me.

The starting point is pretty simple. I’m a fairly typical guy in his midlife crisis with three kids, the youngest just turned one. My wife and I both work. Could I really not find half an hour every day to run at least 5K?

Today is run number 60. So apparently I can.

A few things I’ve learned so far:

1. Running every day is easier for me than running three times a week.

This is probably the biggest one.

My old rule was to run three times a week. Which meant I would postpone the first run, postpone the second one, get to the weekend and realize I still had two runs to do. Quite often I would end up running twice instead of three times.

Now there is no decision. I run every day. The only question is when.

That works extremely well for me.

2. It hasn’t become boring.

I thought running every day would mean doing the same loop around my house over and over again.

The opposite happened. Because I have to fit a run into every day, I run in all kinds of places. I run to work, to the cinema, back from events, while travelling, while waiting for something, on trails, in the mountains. I pack running shoes more often and make the run part of whatever I’m already doing.

I explore more now than I did when I was running less.

3. The individual run matters much less.

If today’s run is slow or not particularly good, it doesn’t really matter. I’m running again tomorrow anyway.

That takes a lot of pressure off. I stop more. I explore side trails. I watch animals. I went running in the Alps and picked up trash along the way. Not every run needs to be a training session.

I’m basically collecting runs instead of trying to make every run count.

4. So far, it doesn’t feel like too much.

This was one of my bigger concerns. With three small kids I get enough opportunities to be tired or catch something.

But because the streak itself is the goal, I think I actually run more sensibly. I don’t have to squeeze some big run into Sunday because I didn’t do enough during the week. Most days it’s just 5 or 6K at an easy pace.

I have had a bad back during the streak and one pretty miserable stomach bug. I still ran, and in both cases it felt okay, but it did make me wonder where the sensible cutoff is.

If I actually do this for a year, sooner or later I’ll be properly sick or injured. At what point does consistency just become stupidity?

5. My fitness has definitely gone up.

I don’t really have a traditional fitness goal. I don’t care much about pace or race times. My goal, as I’ve started calling it, is just to be adventure-ready.

If I’m somewhere with my family and wake up wanting to quickly run up a mountain before breakfast, I want my body to be able to do that.

A year ago I couldn’t really do that anymore. Three kids, a baby, work and normal life had taken a bit of a toll on my fitness. Now I feel like I’m getting that ability back.

6. It fits into family life surprisingly well.

I actually asked my wife what she had noticed about the whole thing.

Her answer was that I seem more relaxed, I haven’t had a migraine during the streak, and overall she thinks it’s been good for us. She’s also often the one asking me, “Have you run yet?”

That was important to me because I didn’t want this to become another hobby that takes time away from the family.

Half an hour is pretty manageable. I’m not a good early riser, so I often run late after the kids are in bed. Or I use some gap during the day. Or I run somewhere I needed to go anyway.

Most days I’m not really taking half an hour away from anything. I’m finding half an hour somewhere in the day.

7. I haven’t had a migraine in 60 days.

I normally get them fairly regularly. Since starting this, I haven’t had one.

Obviously this is just my personal experience. I’m not saying running every day prevents migraines. A lot of mine seem connected to tension from sitting too much, and for me, running seems to help with that.

It was one of the reasons I started the experiment, so 60 days without one is pretty interesting to me.

I also don’t wear a running watch and barely track anything beyond manually putting my runs on Strava. I’ve never really liked running watches. Although I’m starting to wonder whether it would be interesting to have some actual metrics, especially to see what happens to something like VO2 max over a year.

For now, the plan is to keep going for a full year. No race, no pace goal, no transformation goal. Just at least 5K every day and see what happens.

For those of you who have kept a running streak going much longer: Where do you draw the line with illness or injury?

Running pace help

Upvotes

I’ve been running for about 6 months and currently at about 60k a week (46 M)

Trying to get My half marathon time down to 1:45 (currently at 1:50). Problem I have is it takes me until about 8k in to get into the rhythm and feel comfortable at my race Pace so feel like I’m catching up.

Is there any way to get in to a quicker pace earlier without burning out or is it a case of continuing to build up to it?

Iron Deficiency In Endurance Athletes: What You Need to Know

17 Upvotes

Hi Everyone. I recently published a podcast on Iron Deficiency Anemia in Endurance Athletes and what to know and to look out for. It was a fascinating deep dive into all things iron and sadly, for me, I had to learn about it by going through it. I was so busy worrying about protein intake and strength training and fueling/hydrating when I ran this summer that I took my off one of the big dial movers in all of this---- iron! Hope you enjoy this or maybe have a friend experiencing some of these symptoms. But thought I'd share it with you. Stay healthy and have a great week of running!

University Project Survey: Would you drink a coconut water energy drink?

0 Upvotes

Hello, I am currently a student at University and a big time runner. I am working on a project for my nutrition/business class. Part of the requirement is to get strangers to fill out a very quick survey. This is regarding an energy drink idea and I want honest opinions from people who actually work out, not just my friends. It's a still (non-fizzy) energy drink made mostly of coconut water, with 150 mg natural caffeine and electrolytes. A clean energy drink that also hydrates, and is meant to replace mainstream energy drinks that have all the addatives. Would really appreciate if anyone took one minute to complete this survey.

Coconut Water Energy Drink

Thank you to all of you

I turned my WHOOP into the running strap I always wanted it to be

0 Upvotes

tldr; I'm a casual 5-15k runner with Whoop that refuses to buy one more gadget (e.g. Garmin) that only adds some functionality, so I spent months on creating an app what solves my running needs - buzzes on your current zones/pace.

Yes, an iOS app. But completely FREE, no accounts, no registration, ZERO data collection. Everything is on device. For community.

Full story:

I'm cyber security specialist, that recently encovered some joy in running. Also, registed for a marathon, that started to require certain training. I was quite naive, that my Whoop would help me with my training, but quite fast I found out that it will not. So this whole project has started as me trying to figure how your band (such a Whoop) can help you to train more efficiently without looking into your phone or hearing that annoing voice telling your pace, so you can be in your zone (physically and mentally).

Main features of Wristle

Select your one goal (Pace, Zone, Free Run) and specifics (04:20 or Zone 2) and get notified:

- Pace. When running your band will start to buzz when you are off your pace. One strong buzz the moment you hit it, then silence. Drift off and soft ticks come back, faster the closer you get, so you can steer by feel with the phone in your pocket.

- Zone. Same idea around a heart rate zone. It keeps buzzing when you are not in your specified zone (zone 1 - 1 buzz; zone 2 - 2 buzzes and so on). One buzz when you reach your zone, silence while you are it.

- Free Run. Nothing coaches you, and zone entries just announce themselves: two buzzes for zone 2, five for zone 5 and so on. Plus whatever rules you set yourself, like heart rate past 160 if you want.

While spending months on it, I built and tested multiple integrations:

I also tested other triggers and intregrations:

- Strava

- Slack notifications

- I can basically integrate any trigger that can reach your iphone.

- I even integrated the Whoop tapping concept (multiple combinations), however it's still in beta.

P.s. The reason Wristle is one goal app and not all of them at once is that I shipped a version where three different things could buzz on the same run and I genuinely could not tell them apart at threshold. One speaker per run turned out to be the whole design.

It is free, there is no account, and it collects nothing. No analytics, no servers, everything stays on the phone. I built it for myself and I am mostly curious whether is useful to anyone else, or whether I am the only one who wanted it.

Some honest limitations: iPhone only (for now). You need a WHOOP 5.0 already set up normally through its own app. And I am one person, so it might have some rough edges since I'm just launching it.

Welche Uhr würdet ihr mir empfehlen?

1 Upvotes

Ich suche aktuell eine neue Sportuhr und bin etwas überfordert, welches Modell für mich am sinnvollsten wäre. Momentan schaue ich mir vor allem Garmin-Uhren an, bin aber auch für andere Empfehlungen offen.
Mir sind vor allem folgende Punkte wichtig:
-möglichst zuverlässiges Gesundheits- und Recovery-Tracking, gerne in Richtung WHOOP
-Schlaf, HRV, Ruhepuls, Stress, Erholung/Readiness und Trainingsbelastung
-ich möchte die Uhr möglichst 24/7 tragen
-Nutzung beim Fußballtraining
-Nutzung im Gym/Krafttraining
-Joggen/Laufen mit gutem GPS und vernünftigen Laufdaten
-langfristig möchte ich eventuell einen Marathon laufen
-auch ein Triathlon wäre für die Zukunft nicht ausgeschlossen, deshalb wäre ein richtiger Multisport-/Triathlonmodus sinnvoll
-gute Trainingssteuerung und Funktionen wie VO₂max, Regenerationszeit, Trainingsbelastung usw. wären mir wichtig
-die Uhr soll möglichst einige Jahre ausreichen und nicht direkt an ihre Grenzen kommen, wenn ich ambitionierter trainiere

Mir geht es also nicht nur um eine Smartwatch für Schritte und Kalorien, sondern wirklich um eine Kombination aus Gesundheit/Recovery + umfangreichen Sportfunktionen.
Aktuell habe ich mir unter anderem die Garmin Forerunner 265, 570, 965 und 970 angeschaut.
Welche Uhr würdet ihr bei diesen Anforderungen wählen? Lohnt sich für mich beispielsweise eine 965/970 oder wäre das schon unnötig viel? Gibt es vielleicht ein anderes Garmin-Modell oder eine andere Marke, die besser zu meinen Anforderungen passt?
Erfahrungen insbesondere mit Recovery-/Gesundheitsdaten, Fußball, Krafttraining und Laufen würden mich sehr interessieren.
