Good Times at SBYB Kick-Off!

Brilliantly sunny skies and cold air greeted close to 400 athletes yesterday at the Spring Backyard Burn kick-off at Wakefield Park in Annandale, VA.  Good times were abundant as racers negotiated a twisty, fast, and ‘mostly flat’ course.  Thanks to all the racers, volunteers, sponsors, and the park authority for helping to make it all happen.  It was a wonderful day of trail running action! 

Results are now posted.  Photos are now available.

Our next SBYB race is on March 19th at Hemlock Overlook in Clifton, VA.  This technical and hilly course is super challenging and a crowd favorite.  This race only has a few spots remaining.  Register today to guarantee your spot on the starting line.

Team Up or Go Solo at EX2’s Reservoir Relay Trail Running Race!

Calling all Trail Runners!

Grab some friends, start training, and get excited for the second annual Reservoir Relay Trail Running Race.  Held on Sunday, May 21st, this unique format, point-to-point trail race includes the entire 18 miles of the famed Bull Run-Occoquan Trail in Western Fairfax County, VA – some of the most amazing single-track in the DC area!  

The course is divided into three linear segments measuring 5-7 miles each.  Race solo or leap frog the different segments on a two or three-person relay team where the 'active' runner and the ‘on deck’ runner swap car keys for timing chip.  For two person teams, one team member will complete any two segments of the race.

Mark your calendar and get registered for one epic day on the trails!  Hope to see you out there.
