Rocky Gap Challenges Racers at XTERRA EX2!

Beautiful Rocky Gap State Park in Flintstone, MD once again played host this past Sunday to the 13th annual XTERRA EX2 Off-Road Triathlon and Duathlon.  Over 300 athletes were treated to relatively cool summertime temps, brilliant sunny skies, and great trail conditions as they tested themselves on a fun and challenging course which included a .75 mile swim in a clear mountain lake, a 13 mile semi-technical mountain biking segment, and a quad burning 5 mile trail run.  Duathletes followed the same course except they began the race with a 3 mile trail run instead of the swim.    

Congratulations to all athletes for taking on the challenge of Rocky Gap and thanks to all the volunteers, sponsors, and park managers for making this event a huge success.  It was a great day of XTERRA action! 

Results are now posted.  Photos are coming soon.

Blue Crab Bolt Kicks Off at Seneca Creek!

Excellent Experiences were had this morning as we kicked off the seventh edition of the Blue Crab Bolt Trail Running Series at Seneca Creek State Park in Gaithersburg, MD.  Close to 300 racers were treated to beautiful sunny skies and perfect temperatures as they negotiated fun and challenging 5K and 10K courses littered with rocks, roots, and demanding hill climbs.  Thanks to all the racers, volunteers, sponsors, and the park authority for making it all happen.  It was a great day of trail running action!

Results are now posted.  Photos are coming soon.

Our next Blue Crab Bolt race is on Saturday, July 30th at Schaeffer Farms Trail System in Germantown, MD.  The trails at Schaeffer are super fun and include twisty single-track, open field running, stream crossings, and several steep hills. Mostly known as a mountain biking destination, Schaeffer has tons of semi-technical terrain that trail runners love.  Register today to join in the fun!
