The Life of an Ultra-Marathoner It's a combination of fear, determination, and insanity that drives ultra runners. You will endure months of training in extreme conditions at ridiculously early hours of the morning. No sickness, workload or state-issued weather alert is going to stop you now because you are a battle hardened ultra-marathoner and you're tough as nails. About Ultra-Marathon Planet Ultra-Marathon Planet was a project we began after our first ultra-marathon. Over time it has slowly morphed into a full out how-to web site featuring videos, training programs, resources and more. Feel free to use any of our plans and advice at your own risk. Be safe and run happy!
