The Ox Frolic is a race for solos, pairs and three and teams of fours over a tough course. Each lap is 10.5 Km so four laps = a marathon. Ox 50 is back as well with the usual stuff, do enough laps to reach 50 miles and boom! You are done. Thing is there is a generous cut off but if you won’t make 50 miles in that time you will get a 12 hour medal and time so no one goes home empty handed.
