It’s day three of Iditarod 45, and guess what? It’s looking like a game of leapfrog.

Defending champion Dallas Seavey led a pack of mushers down the Yukon River toward the checkpoint of Ruby overnight but was trailed closely by last year’s fourth-place finisher, Wade Marrs. They appear to be running neck and neck, with trackers showing them flip-flopping the lead, depending on when the trackers update.

They were followed by a contingent of top contenders Wednesday morning, including two-time champion Mitch Seavey, Kuskokwim 300 champ Pete Kaiser and 2013 Iditarod Rookie of the Year Joar Leifseth Ulsom.
