About this app

Accomplice is a unified marathon training system for runners who are done wasting time built with Olympic Marathoner Clayton Young.

Most runners:
• Run hard but don’t get faster
• Piece together training from everywhere
• Guess at pacing, workouts, and race prep
• Make avoidable mistakes that show up on race day

Accomplice replaces guesswork with a clear, repeatable loop designed to help you improve every day: learn, train and reflect.
