XTERRA Trail Run Hagg Lake Half Marathon, 10k, & 5k

Trail Run

In 2013 the 10k sold out!  Thanks to you telling all of your friends we have so many people wanting to try trail running – so we added a 5k.  

The half marathon and 10k races start at the same time heading out in opposite directions.  The half marathon takes you clockwise around the entire lake on a well marked course through the picturesque Scoggins Valley. The scenic one-loop course around beautiful Hagg Lake will be sure to challenge even the most seasoned runners, but still be kind enough on the rookies.  Our 10k course is a challenging course that will leave your legs burning.  The new 5k course leaves boat ramp C heading North to follow the half marathon runners and loops around to bring you back to the after party just in time to enjoy all of the festivities.

One clockwise loop around the Hagg Lake Trail. You will make your way through open meadow trails, closed canopy, and some of the most scenic old growth forests in Oregon. It is a moderately hilly trail, with some short steep climbs and descents, roots, rocks and bridges.


This course is guaranteed to get your heart pumping through the scenic trail system at Scoggins Valley. We will send you counterclockwise, onto an epic out and back (kinda like a lollipop shape) course.  View map HERE.


Route will be posted on our Facebook page as soon as it is finalized.  If you want to know as soon as the route is finalized and don’t LIVE on Facebook then sign up to receive our updates (right upper column of this page)
