Marshall Ulrich has run more than one hundred races averaging over 100 miles each; completed twelve expedition length adventure races and climbed the Seven Summits, including Mount Everest. However it was his run from California to New York, over 3000 miles, the equivalent of running two marathons and a 10k run every day for two months straight, that proved to be his most challenging effort yet. Marshall Ulrich shares the gritty backstory of those 52 days running from West Coast to East: across 12 states, in temperatures soaring to over 30ºC to freezing.
