Marathon discovery + coaching, in one place
Find your marathon. Train for the runner you are today.
Every US marathon and half, ranked by a multi-axis Green Score — then a Strava-powered plan that adapts to your real fitness, the weather, and the qualifying time you're chasing.
Free to explore — no account needed to browse.
Discover the right race
Don't just pick a marathon — pick the one that fits you. The Green Score rates every race on terrain, climate, logistics, travel, and field size, so you can reason about difficulty at a glance.
A plan that knows you
Connect Strava and we learn your fitness — observed max HR, VDOT, weekly volume — then build a real 18-week plan with paces tuned to you. No manual zone math, no static PDF.
Honest qualifying odds
Chasing Boston or NYC? See your projected finish at race day and your real qualifying odds — and watch them move from red to green as you train.
The Green Score, like a course rating for marathons
One number from 1–10 (10 = easiest), built from five axes — so a first-timer can weigh a race the way a golfer reads a course.
