Tons of Fun at Prince William Forest Park!

Tons of fun was had yesterday at the tenth annual EX2 Off-Road Half Marathon and 10K held at Prince William Forest Park in Triangle, VA.   Despite the unseasonable and uncomfortable heat and humidity, close to 400 were treated to prime trail conditions as they negotiated demanding twisty streamside single-track, forested fire roads, and several quad burning hills. 

Congratulations to all racers who took on these challenging trails and a huge thank you to all volunteers and sponsors for helping to make this event such a wonderful success.  It was a great day of trail running action! 

Results are now posted.   

Photos are coming soon.

More good times are right around the corner when we kick off the five race Fall Backyard Burn Trail Running Series on October 19th at Lake Fairfax in Reston, VA.  Choose to race either 5 or 10 miles while enjoying cool temps and changing Fall colors.  Come join the fun!  These races have sold out for the past several years so register today to claim your spot on the starting line.

The Monkey Was Cranky Saturday!

After a very fun and successful beginner/junior 8am race at Fountainhead on Saturday,, the skies opened up and the rain fell, hard.  After a short delay, it was clear that we would not be able to hold the sport/clyd/SS/expert race at 10:30am.  So, we postponed and planned to give it another try today.  But, the forecasted scattered and isolated showers turned 8 hours of steady rain.  There was no chance the course would be ready or safe for a race.  So, the sport/clyd/SS/expert Cranky Monkey race at Fountainhead was cancelled. 

We had three potential race dates blocked off our calendar and none of them worked out.  Perhaps this is a sign that this race was not meant to be and the Cranky Monkey is truly living up to its name.

With the above said, a big thank you goes out to all the racers, volunteers, sponsors, and the park authority for helping to make it all happen.

Results and Series Points are now posted.

Quantico Challenges Cranky Monkey Racers!

Athletes were treated to unseasonably cool temps at second race of the Cranky Monkey Mountain Bike Series held yesterday at the Quantico Marine Corps Base in Quantico, VA.  Over 150 mountain bikers hammered it out on a fun and challenging course which included twisty single-track, log ramps, long fire roads, and quad burning hills.  It was an excellent day of mountain bike racing!

Thanks to all the racers, volunteers, and sponsors for making it a great day and a special thanks to Jim Long, John Paul Cooley, and Brandon Farley from the Quantico Mountain Bike Club for getting the course in top shape and to Gary Gutshall and Bobby Brown from Marine Corps Community Services (MCCS) for all of their logistical support. 

Results and Series Points are now posted. 

Photos are coming soon.

The final Cranky Monkey race will be held on Saturday, August 23rd at Fountainhead Regional Park in Fairfax Station, VA.  The trails at Fountainhead are awesome so you don’t want to miss this one.  Register today!
