Filthy Fifty Mountain Bike Race 2023
The Annual Filthy 50+ mountain bike race takes place in San Diego and travels through various sections of San Dieguito River Park and Black Mountain Park. The race takes place on Saturday, October 28 and offers two different lengths, 30 miles, and 50 miles.
Organized by Quick n’ Dirty Mountain Bike Racing, this is the event’s 9th year. The ride is suitable for all skill levels and is fully marked with pink flags and red arrows. There are two courses: a 30-mile ride and a 50+ mile ride that continues on to the Black Mountain Park area where riders will encounter a lollipop and new trails. Fully stocked feed stations will be placed throughout the course to keep riders fueled up.
