Mark Dowdle - American ultramarathon runner and endurance athlete from the Minnesota area. He played football and lacrosse at the University of St. Thomas before taking up running after college. Mark has become particularly known for backyard ultras, in which runners complete a 4.167-mile loop every hour until only one runner remains. In 2026, he won the Arrowhead 135, the Wausaultra Backyard Ultra, and the Last Soul Ultra in Germany, where he completed 94 loops - about 395 miles over 94 hours. He also won the 306-mile BPN Go One More (G1M) Ultramarathon earlier in 2026. His Last Soul performance has put him on the 2027 Big Dog's Backyard Ultra Individual World Championship roster, where he currently holds a 94-loop qualifying performance.
