Escape the summer city heat and head for the mountains! Join us at Rocky Gap State Park in Flintstone, MD for the 22nd annual Rocky Gap Off-Road Triathlon, Duathlon, and Relay.
The triathlon race course starts with a two lap swim in warm clear waters of a mountain lake and the duathlon starts with a 2.7 mile semi-technical trail run. After the first segment, all racers head out to complete two laps of a mountain bike course that includes twisty lakeside singletrack, wide fire roads, smooth grassy sections, and a few rock gardens. Once completing the mountain bike course, racers transition to a 5.5 mile run that has rooty trails, smooth open flats, and a few ups and downs (of course!). All in all, this course is super fun and has challenged thousands of newbies and seasoned vets over the years!
