Head to the beautiful mountains of Rocky Gap State Park in Flintstone, MD for this year's summer classic—now in its 22nd year—where you'll find multiple race formats to choose from, including triathlon, duathlon, aqua bike, and relay options. For 2026, the event features brand-new bike and run courses plus an exciting new sprint race and aquabike format. While you can tackle the sprint distance on a gravel bike, mountain bikes are the way to go for the full triathlon and duathlon distances.
