The marathon is what we're built for: the right work, put where it counts, and a coach who tells you why.
42.195 km has its own physiology, its own pacing, its own ways of coming undone. Most marathon plans are any-distance plans trimmed to fit. Ours begins and ends with the one event, and with the runner training for it.
The Marathon Library brings the practical answers into one place. Start with the question in front of you, then follow it into the training, recovery or race-week decisions around it.
The library makes three different lenses explicit: published research, established coaching convention and the Clinic’s practical judgement.
Turn one recent run into the numbers that matter: what you can race, how to pace it, and how to fuel it. Free, and no account needed.
Free, course-aware pacing for the world’s great marathons: the real elevation, grade-adjusted splits for your goal time, an adjustment for the weather you’re likely to race in, and a coach’s read on where the race is won or lost.

To me, coaching is teaching. I help you understand your own training and learn to read your own running, so the day comes when you barely need me.

Bring on a coach who stays with you, every week to the line. Or build a free plan and get going today.
