Endorphins is a coach and a crew. Thousands of free group runs a year in cities around the world, plus the coaching that gets you to the finish. That is the part a plan on its own can never give you. See the community.
A plan tells you what to run. A coach tells you what to run today, given the run you missed, the weather outside, and the race on the calendar. Here is what you get with Endorphins that Runna leaves out.
Both apps hand you a personalized plan. The difference is what happens after day one: Endorphins builds yours from your actual recent training, not a template, then rebuilds it every week around the runs you logged, the days you missed, and the race you are chasing. Preview one free with the training plan generator.
Run a hard session in 85-degree heat and a flat pace target sets you up to blow up. Endorphins adjusts your workout paces for the real conditions, so an interval effort stays an interval effort. Runna hands you the same numbers no matter the weather. See weather-adjusted pacing.
Link WHOOP, Oura, Garmin, or Apple Health and Endorphins reads your sleep, HRV, and readiness every morning. A bad night eases tomorrow to a recovery run so you absorb the training instead of digging a hole. Runna plans the same week no matter how recovered you are.
Ask a question over text and get a coach-grade answer grounded in your real plan and data. Move a run, flag a niggle, or check today's workout from your messages. Runna keeps everything locked inside the app.
Every week Endorphins reviews how your training went, tells you what it is adjusting and why, and sets up the week ahead. It is the rhythm of a real coaching relationship, not a plan you download once and never hear from again. Runna leaves you to interpret the week on your own.
Finish a run and Endorphins reads it, then follows up: it noticed you ran 15 seconds hot, or nailed the negative split, and adjusts tomorrow accordingly. Real feedback on the run you just did, not silence until your next scheduled workout. Runna logs the run and moves on.
Endorphins is an MCP server. Connect it to Claude or ChatGPT and your assistant can reason over your real plan, workouts, paces, and race predictions, then help you adjust. Runna has no way to plug your data into the AI tools you already use.
Ask how to pace the long run, tweak today's workout, or plan race week, and change your whole week in a single message. It is grounded in your training, not generic advice. Runna offers no true conversational coach that can read and edit your plan.
Add the shoes you run in and Endorphins tracks the miles on each pair, so you know when a favorite is worn down before it turns into an injury. Runna leaves you to track your rotation somewhere else.
When race day comes, Endorphins turns your fitness into a concrete race strategy: the pace to hold, how to negotiate the hills, and where to push. Runna gets you to the start line without a plan for the miles that follow.
Endorphins is not just an app on your phone. It is 2,000+ free group runs a year, race-weekend shakeouts, and a crew in every city that turns strangers into friends. Runna is training software. It has no runs to show up to. See the community.
Endorphins is a US company with group runs in cities across the country and support that runs on your schedule. Runna is based in the UK. When your community, your races, and your coach are all stateside, that closeness shows.
Every device you own feeds Endorphins in real time. It reads your runs and your sleep, adapts your plan, and sends the coaching straight to wherever you already chat: iMessage, WhatsApp, Telegram, Claude, or ChatGPT. See all integrations.
Link your devices in two minutes. From then on it reads every run and every night of sleep, rewrites your plan the moment your data shifts, and sends the next session straight to your texts.
OAuth to Garmin, WHOOP, Oura, Apple Health, COROS and more in under two minutes. Every run and every night of sleep syncs on its own.
It catches a readiness dip before you feel it, reworks tomorrow so you absorb the training, and texts you exactly why.
The adapted session lands in iMessage, WhatsApp, or Telegram, and on your Apple Watch, Garmin or COROS. Nothing to open, ready to run.
Yes. Endorphins does everything Runna does and adds a plan that re-optimizes every week, weather-adjusted pacing, adaptation to your recovery data, a coach you can text, weekly and post-run check-ins, an AI chat assistant that can edit your plan, MCP access to Claude and ChatGPT, shoe tracking, a race-day strategy planner, and a free in-person running community with 2,000+ events a year. Endorphins is US based; Runna is based in the UK. You can build a plan and preview it free.
The Endorphins community layer is free forever. Premium coaching is $19.99/mo, or $9.99/mo billed annually, with a 7-day free trial. See pricing for the full breakdown.
Yes. Endorphins recalibrates your workout paces for the heat and humidity you are actually running in, so a hard effort stays a hard effort instead of setting you up to blow up. Learn more.
