Christmas in July Half Marathon and 5K (Dayton)

Embrace the festive spirit this summer at the Christmas in July Half Marathon and 5K in Dayton, Ohio! On Sunday, July 12, 2026, join Santa and friends for a unique running experience that combines holiday cheer with summer fun. Kicking off from Hollywood Gaming at Dayton Raceway, this event offers both a challenging Half Marathon (13.1M) and an accessible 5K distance, promising a jolly good time for runners of all levels. Participants will earn "chillin' Hawaiian Summer Xmas swag," including a very cool sublimated Christmas In July style shirt or ladies tank top, a cinch sack, custom bibs with unique Christmas names, and a real blinking light-up ornament finisher's medal (with the Half Marathon medal allowing you to dial in your finisher's time!).

The course sleighs its way along the beautiful Great Miami River Recreational Trail, offering a road-type surface with some gentle hills and a mix of sun and shade to keep things interesting. Aid stations are strategically placed every 1-2 miles, providing water and even full water bottles at some stops to help you stay hydrated. Expect typical race day conditions in Dayton with highs around 86°F and lows around 66°F, and about a 19% chance of precipitation, so come prepared for warm summer running. The course is stroller-friendly for those looking to bring the whole family, though dogs are not permitted.

Cross the finish line and dive straight into the post-race Christmas party, starting at 8:30 AM, where your achievements are celebrated with festive treats like frozen snacks, package snacks, root beer, and even one complimentary beer ticket for those 21 and over. Whether you're chasing a personal best or simply looking for a fun, themed run with fantastic swag, the Christmas in July Half Marathon and 5K provides an unforgettable experience in Dayton!
