What is Roast My Strava?
Roast My Strava connects to your Strava account and uses AI to write a roast of your training. Your bio, your stats, your pace, your route choices, and yes, your profile picture — it reads the photo too, which is where most of the direct hits come from. Every roast comes out as an image sized for a screenshot.
It was built by Jason Kuperberg over a weekend in September 2024, as an experiment in pointing a language model at the Strava API. It reached 10,000 athletes in two months on shared screenshots alone. In October 2025 Strava gave it an App of the Year award for "Community Motivation" at the Strava Developer Summit, and that December the story of building it ran in Developer Voices on the Strava blog. It has now been used by over 100,000 athletes and has generated more than 350,000 roasts.
Key Features
Profile roasts
The whole account: bio, profile picture, stats and activity patterns, read together through multimodal analysis. Reading the photo is the part people notice.
Activity roasts
Pick a single activity and get it taken apart on the specifics: pace, route, effort, and whatever you called it.
Year in Sport, roasted
The signature one, and an alternative to Strava's official recap. It reads your total distance, elevation, activity variation and training trends for the year and writes the mean version. An Instagram trend of athletes posting theirs in December 2025 is what carried the app past 100,000 users.
Title generator
Separate from the roasting: it reads an activity and writes three titles that aren't "Morning Run", in a tone you pick (Roast, Clever, Hype or Random), and sets one on Strava with a tap. If you think of it as a caption, same thing: on Strava the caption is the activity title. Compared with the other title tools on the blog.
Shareable images
Every roast renders as an image built for screenshotting, which is how essentially all of this app's growth happened.
Who It's For
- Athletes who can take it — the roasts are written to land, and they read your photo
- Group chats and clubs, where the sharing actually happens
- Anyone bored of a year-end recap that congratulates them
- Not people who want their own data back. You can only roast your own account, and there's nothing analytical here
