The Sycamore Canyon 100k is a multiple loop course run as a solo ultra or with as part of a relay team. Solo runners must complete all 9 laps themselves.
Relay works as follow:
Each runner completes two laps (22.2km/13.7 miles) & one runner completes 3 laps (33.3km/20.6 miles). Each runner can run their laps consecutively or they can reset between laps. It's all part of the strategy!
The Sycamore 100k course is a figure 8 lap course. The top half of the 8 is ALWAYS run clockwise. The bottom half is run counterclockwise on even laps and clockwise on odd laps
