Completing a traditional marathon means running a staggering 26.2 mi (42 km), but each year, more than 70,000 runners worldwide tackle an even greater challenge—the ultramarathon.

Events can last mere hours or span several days. What extreme location hosts “The Last Desert,” a 155.3 mi (250 km) race? Discuss
