Chicago Double Racing Festival pits runners against each other in a test of endurance, both physical and mental. The day begins with a 5- or 10K run, with first place finishers earning a bright yellow jersey. Then, runners take a break for an hour, recouping and preparing for the next leg of their journey. Heats meet back at the starting line to compete once again, this time in a 3- or 5K dash. Every participant earns a medal and t-shirt, with top finishers taking home special accolades and cash prizes.
