width=175Ultra-running (as defined by any running race longer than the marathon of 26.2 miles) requires a whole different nutritional viewpoint when compared to the gels and quick shots of Gatorade normally encountered during a road race up to the marathon. Ultra-marathons most often take place on the trails of national and state parks with the 50K (31.2 miles) being the most popular race distance, then followed by the 50-milerand 100-miler. All these distances are covered with no rest or stopping, except for the occasional aid stations where runners refuel.
