Murrell Park, Flower Mound, Texas
Race Start: 8:00 a.m.
This is an off-road triathlon that includes a 1200-meter swim, 13.4 miles of mountain biking, and a 5.6 mile run. This adventure gives racers the opportunity to rock it on one of the most popular trails in the DFW Metroplex, Northshore Trail (Lake Grapevine). The start takes place at Murrell Park, where swimmers will head out and complete a loop around a cove on Lake Grapevine. After exiting the water, racers will transition to the bike and enter the single-track trail. Traveling in a counter-clockwise direction, riders will head east to do loops 2, 3, and 4, followed by the west section of the trail to complete loops 1 and 5. The mountain bike portion of the race is fast, with a few technical sections to challenge you. Finally racers will transition into their sneakers to rock the final leg of this adventure. Heading east, racers will run counter-clockwise through fast, flowy single-track before raising their hands high through the finish line.
If you sign up as a “trio” then you each do a different leg of the race. You exchange (tag) in the transition area. The first teammate will swim, the second will bike, and the third will run.
We do not have age groups for the relay teams. It is just one division. You can combine any combination of ages or gender you like.
The “duo” teams mean that one teammate does two of the legs and the other does the third leg. You pick the order and the legs that each does. (ie. Teammate #1 could do the swim, teammate 2 the bike, then teammate 1 the
