The Challenge isn’t just a list of race distances: it’s a pathway to total transformation. Whether you're chasing your first 5K or eyeing the brutal beauty of a 100-miler, each milestone is a step deeper into who you can be. Doesn't matter if you walk, run or roll through each race. You can do this.
