Xterra weekend approaches. There are still spots available for Saturday’s 10K and 21K trail races. On Sunday, pros and amateurs will toe the line to swim, bike and run all over the James River Park System and Brown’s Island in the Xterra East Championship. Spectators will get to experience the race in a whole new way this year thanks to Luck Stone. And speaking of Luck Stone, if you go by their tent during the race you can enter to win a mountain bike — a Specialized RockHopper Comp 29er. Raffle tix are $5 each or 5 for $20. The bike, donated by 3Sports, retails for $1,100. The money raised will go to the Friends of the James River Park System.
