Leaders in Bev Stevens' 8-dog sprint team round a corner while competing in the Norma Rasmussen Memorial race on Sunday, Feb. 15, 2015, which is the only race to be held this season at the Tozier Track in Anchorage.

Running on snow made soft by 35-degree temperatures, Michael Tetzner mushed to victory in two races Sunday in the Norma Rasmussen Memorial Challenge, the season's first sprint race at Tozier Track.

Tetzner and his team of 10 sled dogs forged a three-minute victory in the 12-mile race, and his team of eight dogs took a 47-second win in the eight-mile race.

In the 12-miler, for teams of 12 or fewer dogs, Tetzner finished in 35 minutes, 4 seconds to beat James Wheeler's 12-dog team, which placed second in 38:12.
