This is an open water swim at Lake Habeeb. The organizer's wetsuit note: wetsuit legal up to 78 F (USAT rule).
From the organizer's own race information (source). Venues and rules can change from year to year; the race's current athlete guide decides.
Around July 12, Lake Habeeb typically runs about 82°F at the surface (81 to 83°F across 2011 to 2020). The water usually runs above 78°F at this date: wetsuits are allowed but make you ineligible for age-group awards.
A model estimate from the USGS lake temperature model (daily surface temperatures for US lakes), not a measurement. Wetsuit cutoffs are USA Triathlon age-group rules. The race's own water temperature reading on race morning decides.

Faster than most Maryland sprint triathlons
The fastest quarter of the 2026 sprint triathlon field finished under 1:06:55, against 1:24:58 in a typical Maryland sprint triathlon, so times here run 21 percent faster.
Compares the fastest quarter of each field, so walkers and first-timers do not skew it. It reflects the course and the field together: a flat course, cool weather, or a competitive crowd all make times faster.

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, Aqua Bike, and Relay (formerly XTERRA EX2). For 2026, we’ve re-imagined our summer classic and created new bike and run courses and added a sprint race and aquabike. While the sprint course could be done on a gravel bike, we recommend mountain bikes for the full triathlon and duathlon.
