Alpine Shop Off-Road Racing League - Spring Trail Run Series 2015 presented by Marmot

Turn a typical Thursday night in May into an adventure!

Starting Thursday, May 7th, 2015, Alpine Shop and Columbia Sportswear will offer a Spring Series of four trail runs at Castlewood State Park.

Each run starts at 6:15 pm in the evening, and we'll follow a brand new course for each week, along with a few new challenges just for the adventure of it. Kids are welcome, too!

Runners at Alpine Shop Trail Run Series Race HQRun First, Party After!

We will have after-race food and a variety of beverages (for both the over-21 and under-21 crowds) after each week's run. We’ve also partnered with our vendors for some great weekly give-a-ways and series prizes. Did you know that Alpine Shop's YETI Coolers can keep cans cold for hours? Come see for yourself!

Race Distances:

Distances will vary each week depending on the trails used, but will remain between a 5k and 4 miles. We will reveal the actual running course each Monday before Thursday's race at the Off-Road Racing League website.
