Brief Description: The Alien Half Marathon will start at the Douglas County Fairgrounds.  The route begins at Seller’s Gulch Trail and goes west to connect with East Plum Creek Trail shortly after.  The route will stay on East Plum Creek north all the way to The Meadows before returning along the same path.

More Info: Headlamps or some kind of personal lighting is required as there are spots along the course that are not lighted.  Shirts are men and women’s cut.  Women’s sizes run small. MYLAPS BibTag timing technology provided by Zulu Racing will be used to trace finish times.

The timing is planned so the average runner will start in daylight and finish in the dark!
