The 13th annual XTERRA Oak Mountain off-road triathlons and trail runs return to Oak Mountain State Park in Shelby County, Alabama on the weekend of May 19-20.

The main event combines a 1.5km swim, 30km mountain bike and 10km trail run. For amateurs, there will be 51 spots into the XTERRA World Championship to be held October 28 in Maui up-for-grabs, and for elites, $15,000 USD in prize money and points in the XTERRA Pan Am Pro Series.

XTERRA will also offer a shorter distance Sprint race – 750-meter for the swim, 15km mountain bike and a 5km trail run, and an even shorter distance Xticer race which mixes a fun 200-meter swim with a 10km mountain bike and 2km trail run.

You can also create a two or three-person relay team to conquer the Sprint or Full distance races.

And, runners will revel in our 5, 10, and 21-kilometer trail runs.

Plus, Paul Mitchell stylists will be on-site giving professional hair cuts in exchange for a $15 (or more) donation to the Challenged Athletes Foundation with 100% of the proceeds benefit CAF.
