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!
