The 2021 Run With The Deer Flies 25K & 15K will be held on Sunday, July 25, 2021.  We are looking forward to returning to Camp Seph Mack near Penn Run, PA. 

The Deer Fly is a fun and challenging trail race with a mix of single-track trails, pipeline roads, swamps, hills, and creek crossings.  Aid stations approximately every four miles, but carrying water is strongly recommended.  Post-race doughnuts, chocolate milk and more.

Races are each capped at 100 runners.  Please register early to avoid disappointment. 

Race shirts are guaranteed to those who register by July 16th.  Shirts are available after that date and on race day only as supplies last.

Wearing of masks before and after the race is required.  CDC guidelines on masks and social distancing are to be followed as applicable at the time of the event.

Refunds available only if the race has to be cancelled.  No refunds or deferrals if the race is conducted.
