About the Run Happy 50K
The 50K is the headline race of Run Happy, a laid-back trail day at St. Patrick's County Park that also offers a marathon, half and 10K. The first official edition was held in 2022.
The cutoff is generous: holding a 15-minute-mile pace is enough to start the last lap in time.
