Water Gap 50k and Half

Water Gap 50k and Half is held in Milford Township, Pennsylvania, on September 26, 2026. Organized by Red Newt Racing, the event offers two trail distances: a 50K (31 miles) starting at 8:00 a.m. and a 25K (about 15.5 miles) starting at 10:30 a.m. Both are run on trails in the Delaware Water Gap area of northeastern Pennsylvania, and the late 25K start lets those runners travel in the same morning.

Consider the 25K if you run half marathons and want a longer, hillier trail effort, and the 50K if you are ready for a first ultra or want a fall race at a familiar ultra distance. For the 25K, 10 to 12 weeks with a weekly long run on trails and some climbing will do; for the 50K, plan 16 weeks, extend your long run to four hours or more at least once, and practice eating solid food while moving. Trail shoes with grip and a plan for carrying water between aid stations will make race day easier on either course.
