About the Event

Voted OCR Buddy People's Choice Award winner for the World's Best Small Obstacle Race Series, Highlander Assault Obstacle Race, our Classic obstacle course race features an open 5k and 15k option, as well as, an 5k competitive (elite) and 15k endurance heat. From beginner to pro, we have you covered. Our Scottish Highlander themed race comes complete with your classic obstacle race staples, from technical monkey bar style rigs to atlas stone carries. Highlander also, adds a twist of the old world including challenges, such as archery, to caber carries. Come join us, you won't regret it!

You can also join us for our night version, Dark Ages Night Obstacle Race. Traverse our 5k torch lit night OCR with illuminated obstacles, bonfires and more, and yes there is a competitive heat!

For those who enjoy a fright, Highlander Assault LLC also offers an immersive 5k Haunted Highlander Trail Run, which is packed full of live haunted actors, animatronics, and Halloween themed scenes. This run does not have a competitive option, but trust us you wont want to miss this one!

All three race events, those who finish will receive a courtesy race medal and t-shirt.
