Description

May 30, 2026 – The Full Marathon Returns!
We’re excited to announce that the Full Marathon is coming back on May 30, 2026, and will also be part of our September event. Start planning now for your next Boston Qualifier on this beautiful, fully paved downhill course, no tunnel, no dirt, no BQ penalty. 

There’s no excuse not to do the dam thing!

The race finishes in front of the historic McMillin Bridge (elevation 200′), with a total net elevation loss of approximately 1,200′.

Half Marathon
The Half Marathon begins in the scenic town of South Prairie (elevation 467′) and follows a gradual downhill route along the paved Foothills Rail Trail. Runners will enjoy a picturesque journey through farmland and forest, winding alongside the Carbon River and finishing in front of the historic McMillin Bridge (elevation 128′). The course features a net elevation loss of 339 feet.
