Spring Forward Half Marathon & 10k

Welcome to Ascent Endurance Group's Spring Forward Half Marathon! We are excited to expand our annual early spring half marathon (and new 10k option), thanks in large part to the support of our friends at Badger State Timing. While we're going more formal, we still expect a low-key community event, with a few added pieces to this year's run. 

Whether you're looking to tune up for the Boston or another spring marathon, testing your fitness after a Wisconsin winter, get in a workout with others, or just want to knock out your long run before the time change, we're glad to have you joining us! Please let us know your estimated pace so we can help group athletes with similar goals together. 

The half marathon course is 2 laps of Madison Arboretum (roughly 10k per lap), followed by a ~1.1k add on in Vilas Park. The 10k course is one lap of the Arboretum.
