About this app

Become the fastest marathoner you've ever been.

Accomplice is the complete marathon training system built with Olympian Clayton Young for serious runners pursuing meaningful PRs.

Most marathoners train alone.

They piece together advice from YouTube, podcasts, and friends. They wonder if they're doing the right workouts, struggle to stay motivated through the build, and don't have access to expert guidance when questions come up.

Accomplice solves that.

Train With a Proven System
Get a personalized marathon training plan built around your pace, goals, experience, and race date. Every workout is designed using the same principles Clayton Young used to become one of the fastest marathoners in the world.

Learn What Actually Works
The Run Faster Marathons course teaches the principles behind effective marathon training so you understand not just what to do, but why you're doing it.

Train With Others
Join seasonal marathon training groups filled with runners pursuing similar goals. Stay accountable, learn from others, and build alongside people who understand the process.

Get Guidance From Clayton Young
Attend coaching calls, ask questions, and learn directly from Olympian Clayton Young without paying for private coaching.
