About this race

Mount Diablo provides spectacular views of the San Francisco Bay Area and surrounding valleys.  The 4 mile course is relatively flat and fast within Mitchell Canyon.  The longer events are mountainous and very scenic. (Distances are accurately measured using a Rolatape® surveyor's measuring wheel.)
