Fueling that reads the plan: hard days eat like hard days.
Three pillars
The whole athlete, in one system.
Fuel
Targets that move with your training.
Calories and macros that shift with today's load, your block, and the race you're chasing. Not a static number you set once and forget.
Train
Plans you can see the logic of.
A deterministic engine that builds your whole season backward from race day: VDOT, periodization, real methodology named out loud. Never a black box.
Recover
Know when to push.
Your wearable's recovery signals, read in real time and turned into one clear call: attack the hard parts today, or back off and bank it.
How it works
One engine. Your whole season.
Add your races.
Set your intent: A, B, or C; interested through registered. Your race calendar becomes the plan's source of truth.
Sync, or log it yourself.
Connect a wearable for real-time recovery and training data, or log it by hand. Your call, either way.
Train the plan.
The engine periodizes everything (fuel, sessions, recovery) into one block. An AI coach explains the why, and reads your data without ever inventing it.
Iron sharpens iron
Built to race together.
Training alone builds fitness. Training with people chasing the same start line builds something harder to quit.
Race calendar
A / B / C intentEvery race carries an intent, from interested to registered. The engine builds your season backward from the ones that matter.
Head-to-head
Coming soon5K head-to-head · PRs on the line
Challenge a friend: race your PRs, your projections, or the same start line. A running record of who owns what.
Communities of shared knowledge
Find the people training for your race, your distance, your city. Share what your block looks like, see what theirs did, and show up on race day already knowing half the field.
Most apps show you what you did.
Athletos tells you what to do next, and why.
Built on methodology, not vibes. It works alongside Strava, Garmin, Apple Health, and WHOOP, and no wearable is required to start. Log it yourself, and the engine still builds your plan.
Ready
