The 11th Annual Filthy 50+ will take you through various areas of San Dieguito River Park and Black Mountain Park. Fast and flowy for all skill levels. The 30 mile riders will head out and turn around at the 15 mile mark and the 50+ mile riders will continue on to the Black Mountain Park area where you will encounter a lollipop and new trails to go with it! The course will be fully marked with Pink Flags and Red Arrows. Fully stocked feed stations will be placed throughout the ride to keep you fueled up.

The primary goal of the Filthy 50+ Fun Ride with Benefits is to bring the mountain biking community together and to celebrate what we all love to do, RIDE OUR BIKES! Additionally, we want to bring awareness concerning the trails we ride on, as well as give back to the organizations that keep us riding on those trails. As part of the Filthy 50+ we urge you to help us give back by donating to the SDRP Bike Patrol.
