Most plans are a template sorted by race distance. Same weeks, same paces, whether you run 15 miles a week or 50.
Your watch records the pace, heart rate, and effort of every run. Your plan never looks at any of it, and no coach has time to review every run.
Miss a run, get sick, or have a breakthrough week and the plan stays exactly the same until race day.
Your plan is built from your recent runs, your race goal, and the days you can actually train. No two plans are the same.
Connect your watch and every run is read for pace, heart rate, and training load, so your coaching reflects what you actually did.
Miss a run or crush a workout and your upcoming weeks adjust. Your predicted race time updates after every run.
After every run and every night of sleep, your coach reads your data and texts you what changed and why. Reply like you would to a friend and your plan updates. Your coach texts you in iMessage, WhatsApp, and Telegram.
An Olympic Trials qualifier, a physical therapist, and a strength coach built the training principles your plan runs on.
Huge PR From This!
The tech even noticed that I wasn’t keeping up with the original plan (oops!) and scaled back to something more manageable! Hugely helpful! Got a 21 minute PR!!

Great for training
After a few weeks it started nudging my tempo pace up on its own based on how my runs were actually going… It genuinely feels like it’s paying attention to my training instead of just spitting out a static PDF.

A Game-Changer for Training
If you have to miss a run or need to shift your days around, it immediately adjusts without making you feel like you’ve fallen behind.

App & Community for everyone
I used the endorphins training program to train for the Brooklyn half this year and shaved 5 minutes off my time for a new PR.

Excellent Training App
I don’t feel overworked, and I like that the app adjusts suggestions as we go. I also like that the app will adjust due to local weather conditions.

Great training & community!
I originally found Endorphins for the Philly Marathon shakeout run and knew I needed to find the group when I went back to Pittsburgh!
