Crew and Pacing:
Ultra running is a community sport and we encourage crew and pacers! All distances are allowed crew and are able to access their runners at the Livery (start/finish) and Hart-Lee Homestead aid stations. Each runner will be given one crew pass. This pass must be on display when parked in the Grouse Mt. parking lot for the Hart-Lee Homestead aid station.

Pacing is only allowed for the 100 mile and 100k. 100k runners are allowed a pacer on the last lap or after sunset (8:15PM). 100 mile runners are allowed a pacer at mile 44.4 (Livery aid station). Runners are allowed as many pacers as they like, but only one at a time.

Parking will be located in the Livery/Equestrian and nearby parking lots. All runners will be directed to the appropriate lot. To allow the longer distance runners (100m, 100k) to have access to their vehicles during the race, these runners will be given priority to park in the Livery/Equestrian parking lot. The parking is limited and we ask that runners carpool when possible.
