Mark Nassi

Mark’s endurance adventures began with road marathons in high school and have included triathlons, team adventure races, and trail ultramarathons. He has ridden his bike across Patagonia to the Straits of Magellan, looked out from the top of Mt Blanc (and hopefully Kilimanjaro just prior to the WMC), and ran up to 100 miles across the Alps and Dolomites in Europe, the Sierra and Rockies in the USA. Mark, who is originally from Istanbul, Turkey, is very excited to take part in the World Marathon Challenge.
