About

Aspen Valley Marathon takes place on July 17, 2027, in Aspen, Colorado. The marathon (26.2 mi) starts at 6:00 a.m., the half marathon (13.1 mi) at 7:30 a.m. and a 5K (3.1 mi) at 10:30 a.m. The course is USATF-certified, a Boston qualifier, and designed for speed with more than 420 metres of net descent.

A fast, descending, certified course is exactly what a qualifying attempt wants — but Aspen sits near 8,000 feet, and no amount of downhill compensates for that if you arrive from sea level the day before. Either give yourself two weeks at altitude or accept that the descent is buying back what the air is taking away, and race on effort rather than on a target split.
