Half Marathon races near Chambersburg

Chambersburg Base Miles

Chambersburg hosts 24 Half Marathon races in 2026 within 80 km of the city centre — upcoming dates, recurring series, and other races nearby, all in one place.

Locals run the borough from the creeks outward, with Conococheague Creek and Falling Spring Creek giving easy town miles before the roads roll toward Caledonia State Park. Chambersburg Road Runners Club keeps the simple line: We run because we can! The first route is 46 km with 91 m of gain, so it works for steady Z2. The second route is 32 km and gains 363 m when you want bite. The Great Appalachian Valley Race, Solstice 5k/10k, Race Against Poverty, Firecracker 5K, and ArtShip 10k give the calendar real anchor events.

Franklin County Cyclists make Chambersburg feel like a proper riding town, especially when the route points east and up into Michaux State Forest. The typical route covers 2 km with 484 m of gain through countryside, a small valley, and a mountain side. Biesecker Gap Rd, White Rock Rd, Broad Mountain Rd, Gilbert Rd, and Behind Mont Alto cover the gravel menu. Shearer Rd runs 3 mi, so it is the long pull. Michaux Grvl 2026, Camp Michaux Gravel Grinder, Michaux MTB Marathon, and the Mid-Atlantic Regional Road Race Championships are the big anchors.

Spring and fall are the best months here, because the Cumberland Valley gives you cool starts, clear tempo days, and enough Appalachian edge for honest base miles. Summer brings an average July high around 86°F and a low around 67°F, so locals move intervals early and save longer Z2 for shaded roads near Caledonia State Park or Michaux State Forest. Winter changes the rhythm when January sits around 23°F to 41°F. Runners keep town loops and track work alive, while riders lean into gravel windows, careful road miles, and whatever singletrack or cyclocross legs the freeze allows.
