Aid stations and water points are placed on the courses and are named in the course plan, including Rancho Canada del Oro, Lisa Killough/Cottle Trail, Rancho San Vicente, and Calero Start/Finish aid stations. Drop bags may be checked at bib pick-up and accessed at the Calero aid station and select intermediate aid stations; all drop bags are returned to the Calero aid station after station closure.
Race management uses bib color coding by distance and enforces time limits and intermediate cutoffs; examples include a 4.5 hour limit for the half marathon, a 6 hour limit for the 16 mile, and a 9.5 hour limit for the longest distances.
Parking is at the Calero parking lot on McKean Road; carpooling is encouraged. Volunteers are requested to support aid stations and receive a future race entry in return. Visit the organization's website for the most recent information.
