Urban Assault Mountain Bike Race

Get ready to race your mountain bike on some of the best and toughest urban single track the East Coast has to offer.

The James River Park trails will give local mountain bikers and visiting riders alike a chance to test their skills. The rock gardens, short steep climbs, creek crossings, fast downhills, and twisty single track are both technically challenging and physically demanding. The hard work and mostly volunteer effort that has gone into maintaining and developing these trails make the Urban Assault an unforgettable MTB experience. Even though we have a Beginner division, we wouldn’t recommend this race for newbies.

PLEASE NOTE: The Urban Assault course will be marked in the customary BLUE arrows.

The 2020 course will follow the James River Park System trails in a clockwise fashion, which is the opposite direction of what we have done the past two years.

The course will start and finish in the Belle Isle parking lot adjacent to Tredegar Street. Racers then will ride up the gravel road and take a hard right up to the Lee Bridge. Cross the bridge, veer right and follow the course parallel to Riverside Drive and onto the Buttermilk Trail. Continue west on Buttermilk to Reedy Creek.

Head down through the far left “chunnel” or culvert, up the rocks and then make a clockwise lap of Forest Hill Park. Cross the concrete bridge before heading back through the culvert. Continue west on Buttermilk and descend carefully down the rocks below the Boulevard Bridge. Cross the Boulevard Bridge and turn left to access the North Bank Trail. Follow North Bank up the wooden ramp and the Stairway to Heaven climb. Turn right to continue on the North Bank Trail back to the finish at the Belle Isle parking lot. (If you are doing the 20-mile course, you will head left and back up to the Lee Bridge and do another lap.)

To get an idea of what the trails are like, check out this course preview video.
