Run With The Deer Flies 25K, 15K & 8K

About the Event

The 2026 Run With The Deer Flies 25K, 15K, and 8K will be held on Sunday, July 26, 2026. Three distances to choose from, including the 8K that was added last year. This proved to be a popular addition for new trail runners as well as those who would like a shorter distance.

We are looking forward to returning to Camp Seph Mack near Penn Run, PA and hope to see you there. The Deer Fly is directed by trail runners for trail runners.

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 burgers and hot dogs grilled up by ultra runner Ryan Knecht.

The Deer Fly benefits Indiana County Parks & Trails and Citizens' Ambulance Service.

Finishers' medals courtesy of Bethany Serafin Awalt of Valley Village Oral Surgery of Pikesville, Maryland, Plus random drawings for eight $25.00 Luigi's Ristrarnte gift cards, four for the 8K, four for the 15K and four for the 25K, compliments of Luigi's and Bernadette Drew, Bel Air, Maryland.

Deer Fly Swatters, a Deer Fly tradition, are being supplied by Chris Sharbaugh, Indiana Chiropractic Clinic, Indiana, PA.

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

Race shirts are provided courtesy of Allied Milk and are guaranteed to those who register by July 14, 2026. Shirts are available after that date and on race day only as supplies last.

No rain date. No refunds or deferrals if the race is conducted.
