About

The Run Happy 50K takes place at the Potato Creek State Park Nature Center in North Liberty, Indiana, in early May, on well-marked trails. Several competitive distances are available, all designed for athletes looking for a challenge: a 50K (31.1 miles) made up of five loops, which starts at 8:00 AM; a marathon (26.2 miles) at 7:55 AM; a half marathon (13.1 miles) at 7:50 AM; and a 10K (6.2 miles) at 7:45 AM. The trails offer technical variety and natural scenery. Whether you are an ultrarunner aiming for the 50K or chasing a personal record at the half or full marathon, the event gives you a platform to push your limits and meet other athletes.
