Course and logistics
The course uses the Fox River Trail and Glacial Drumlin Trail. The organizer describes the route as a little long and flat. All runners start at the E.B. Shurts Building in Waukesha. The half marathon route is one loop repeated three times; 5K and 10K routes use turnarounds at Sunset Drive and the trail intersection as described by the organizer. The course includes two aid stations stocked with water, sports drinks, and energy gels. Parking is limited at the building; street parking is available nearby and participants are asked not to use business parking lots. Early half-marathon starters receive a chip time but are not eligible for age-group or series awards; the early-start course may not have full markings, marshals, police, or aid stations in place.
