Frontline OCR is a 6.2mi 30 obstacle course race that was my first OCR last year and was even more fun this second year. The course and obstacles were different than last year and very fun and challenging! I can't wait to do it again next year!

Great local OCR

Great local OCR. Supports first responders and the military. Great obstacles and course layout. Tough obstacles mixed in with regular, easier obstacles. Awesome experience.

Hands down my favorite OCR race of the year. Special Forces adds an extra challenge and makes it a true obstacle race. This was well organized and has an amazing crew!

This was my 5th time running Frontline OCR, and I was very impressed with the way the race continues to improve. As a local OCR they really deliver a top quality race with very challenging obstacles. I think this course might be a bit tough for a beginner, but despite the challenging obstacles, everyone is sure to have a great time.
