100. runners have 33 hours to complete the grueling 100-mile course. most run all night, and many don't finish. for amy, the steep and narrow trails made it difficult to run on her prosthetic, and she missed the timed cut you've at mile 26. >> i feel great. i just missed the time cutoff. this is just as much of a success rather than a failure. if you can learn from it, you walk away a smarter person. i will absolutely be back. still ahead, what could be more motivating than a four-legged teammate?
