An ultramarathon is the name given to any race longer than a marathon (26.2 miles). Ultramarathon length varies between 30 miles, 50 miles, 100 miles, or 100 kilometers. These races can last from anywhere between six hours and six days. They are run in loops with occasional breaks between groups of mileages. The breaks allow the runners to eat and use the bathroom. Typically, when someone mentions running, the body type that comes to mind is lean, thin and toned. Mirna Valerio does not fit into these categories. She also is not just starting her running career. She is not a “before” body type. Mirna is an ultra-runner.
