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.
