From 3:37 to 2:40. Some of it was talent — all of it was learnable.
In 2019, Parker ran his first marathon in 3:37 — in a soccer jersey. In 2024 he ran Boston in 2:47:29. In 2026 he came back and ran the 130th Boston Marathon in 2:40.
That 57-minute drop didn't come from genetics. It came from figuring out — sometimes the hard way — how training volume, fueling, recovery, shoes and racing strategy actually fit together. That playbook is what you're hiring.
Parker coaches a small roster of athletes across the US from his base in Atlanta: first-timers, PR chasers, and runners hunting a Boston qualifier. Every plan is written from scratch. Every week, a human looks at your data.
