Ultra runner Jim Walmsley delivered another resounding victory at the Mesquite Canyon 50k, shaving more than 20 minutes off the previous record in gruelling desert terrain.
Walmsley, who's expected to run in the Western States in a few month's time, crossed the finish line at the Arizona race in just three hours, 40 minutes and 18 seconds on Saturday. That's an average pace of more than 14 kilometers, or roughly 8.7 miles, per hour.
