About this race

A great second year indoor ultra marathon. Three different ways to challenge yourself with a 3,6,and 12 hour events. Your total distance ran will be based on how many laps you complete. We are using a new idea of tracking laps. Every lap you complete you put a marble into your tin. At the end of your event your total marbles are counted and that will determine your total distance.
