Features built for real runners

A coach-built plan that adapts to your life, workouts you actually understand, and a community that shows up. Here's what you get. Start training free or log in.

Everything you need to reach your goal

• Build a personalized plan — tell us your goal and we generate a coach-built plan calibrated to your real fitness, not a one-size template.
• Adapt as you go — our coaching system monitors every run, missed day, and PR, then adjusts your plan to keep you on track.
• Connect your device — link Apple Health, Apple Watch, Garmin, COROS, WHOOP, Oura, Suunto, Polar, or Wahoo in a tap. Every run flows in automatically.
• Achieve your goals — see your fitness climb and your predicted race time drop, workout by workout.

Syncs with your gear

Endorphins syncs with Garmin, Apple Health, Apple Watch, COROS, WHOOP, Oura, Suunto, Polar, and Wahoo, so every run flows in automatically. See all integrations.

A plan that knows your week

Open the app to exactly what to run today, and a plan that already adjusted for the run you missed, the race you're chasing, and the days you can train. Re-optimized automatically every week, with a Flash Score that shows how sharp you are today. Explore adaptive plans.

Know your finish time

See the exact time you're on track to run, and the pace to hit it, calculated from your real, recent training. Live predictions and goal-pace targets, updated every week as you get fitter. See race predictions.

A coach in your pocket

Ask anything, anytime: how to pace the long run, a tweak to today's workout, what to do on race week. Unlimited coach chat 24/7, personalized to your plan and data, and you can adjust your whole week in a single message.

Tracked, mile by mile

Live GPS, splits, and audio cues as you run, then every mile syncs straight back to your plan and Flash Score. Works with Garmin, COROS, WHOOP and Apple Watch — no manual logging, ever. See run tracking.

Watch your plan take shape

The same engine that powers your in-app plan lays down a periodized build with foundation, build blocks, recovery weeks, and a race-week taper, for the 5K, 10K, half, or marathon. Preview a plan free with the training plan generator.

More than a coach. A running community.

Plan routes, find your people, and bring your city together. The community side of Endorphins is free forever, with no plan required.

• Build routes — draw a custom route, see distance and elevation as you go, save favorites, and share them with your crew.
• Race chats — one auto-created chat per race for pace groups, shakeout meetups, and race-day logistics.
• Host runs — create a group run in seconds; we handle RSVPs, reminders, and the map.
• Challenges — run miles and earn prizes from partner brands just for logging your miles.
• Spotify — connect Spotify and the playlist you ran to rides along with your activity.
• Reactions — drop an emoji on a friend's breakthrough and hype the long run nobody wanted to do.
