Rocky Gap Off-Road Triathlon, Duathlon, Aqua Bike, and Relay

About the Event

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!
