Course and race logistics
The half marathon route is one lap around the Madison Arboretum, followed by an approximately 1.1 km add-on through Vilas Park, finishing with a second lap around the Arboretum (each lap is roughly 10 km). The 10k is one full lap of the Arboretum. On-course support and volunteers will be present for three hours after the race start; participants who continue beyond that period will be without course support.
Indoorance Athletic Club is offering 8- or 12-week training programs for either distance. Registrants are asked to share an estimated pace to help group runners by similar goals; race organizers hope to provide pacers for a range of goal times. Donations are welcomed to help cover event costs. Sponsors listed for the event include Ascent Endurance Group, Badger State Timing, Indoorance Athletic Club, Wisconsin Runner, and Skratch Labs.
