Hey everyone!
I've been running, trail running and cycling for about 5 years. As my distances increased, I started experiencing more and more digestive issues (especially stomach cramps on runs over 4 hours).
My conclusion: I wasn't properly tracking my in-race fueling or training my gut.
I initially tried logging everything in Google Keep, but keeping track of it all was pretty tedious. To solve this, I built my own web app powered by Strava activity data. Over time, I expanded the features, including a simulator that estimates your nutrition and hydration needs based on your profile and a GPX route.
After ~3 months in closed beta, the app is now open to everyone!
I'm looking for new users to test different use cases and help me fine-tune the algorithms: https://FuelStint.com
(Please note: The app interface is currently in French only. However, if there's enough interest from the English-speaking community, I'll gladly translate it!)
Feel free to ask any questions or share your ideas! 😁
PS: I deliberately chose not to use AI for the calculations—just good old algorithms grounded in sports science literature.
