David Sinclair

David is one of the best ultrarunners in the world and in 2024 was named the 3rd ranked ultrarunner in North America after breaking the course records on both the Speedgoat 50k and JFK 50 mile races. He has set numerous FKTs and is the only person known to have made it up to the summit of Mt. Washington from Pinkham Notch in under an hour. David was a highly ranked nordic athlete in college, then transitioned to marathons where he ran a PR of 2:16. He has transitioned to ultras recently and is spending the winters competing on the World Cup circuit for Skimo, with an eye on making the 2026 Winter Olympics.

As a native of Vermont who went to college in New Hampshire, David knows the rugged terrain of northern New England and has coached Nordic skiers and runners for many years. He is excited to help athletes of all levels achieve their best. Read Ultra Running Magazine’s write up on David and why he was ranked Number 3 for US Men’s Ultra Runner of the Year.
