The Experience

Set against the backdrop of Northern Colorado's stunning Poudre River Canyon, the Fall Equinox Half Marathon is a celebrated event. This point-to-point course, first run in 2012 and now in its 13th edition, offers a net downhill profile, making it a popular choice for those seeking a personal best.

Runners travel from approximately 32 states to experience the picturesque scenery along the Cache la Poudre River, Colorado's only designated Wild & Scenic River. With a median field size of around 1,761 finishers and a growing trend, the race has cultivated a loyal following, with about 20% of participants returning in subsequent years. The event is known for its great swag, including a tech tee, and a festive post-race atmosphere with music and beer.

While the course is largely downhill, reviews mention a gradual descent that is quad-friendly, though some note a sloped road surface and a challenging uphill stretch in the final miles. Logistical considerations include shuttle transportation from parking areas to the start line, as supporters may have limited viewing opportunities along the course.
