The Iditarod has crowned a new Norwegian champion: Joar Leifseth Ulsom. The 31-year-old pulled under Nome’s Burled Arch at 3 a.m. Wednesday with eight dogs in harness to claim his first championship, taking the win in Iditarod 46. Ulsom is the first Norwegian musher to win the thousand-mile sled dog race since Robert Sørlie in 2005. Girdwood's Nicolas Petit arrived a little over two hours later, and he spoke to reporters about how his race went and where it went wrong.

There was a major shakeup at the front of the 2018 Iditarod on Monday, when Joar Leifseth Ulsom slipped past previous leader Nicolas Petit while Petit lost the trail on the Bering Sea coast between Shaktoolik and Koyuk. The table is now set for Ulsom, first to White Mountain and only 77 miles from the finish in Nome, to win his first Iditarod championship and the first for a Norwegian -- or anybody else not originally from the U.S. -- since 2005. But, as we hear in this episode, a lead and a long rest at White Mountain hasn't always translated to a win. Meantime, many of mushing's old guard are happy to pass the mantle to the next generation of elite mushers (not including defending champ Mitch Seavey, still mushing near the front in third place).

It's Monday and the frontrunners in the 2018 Iditarod are on the Bering Sea coast, venturing out on a trail over sea ice from Shaktoolik to Koyuk. Alaska Public Media's Zachariah Hughes caught up with the top three -- Nicolas Petit, Mitch Seavey, Joar Leifseth Ulsom -- in Unalakleet on Sunday, as well as the legendary musher DeeDee Jonrowe, who scratched earlier in what she says was her last Iditarod after 36 total starts. We also hear from a Norwegian mushing reporter on four-time Iditarod champ Dallas Seavey's foray into the Finnmarksløpet, Europe's longest sled dog race.

As Girdwood's Nicolas Petit, Norwegian Joar Leifseth Ulsom and defending champ Mitch Seavey lead a chase pack to Unalakleet and the Bering Sea coast, we talk to Alaska Public Media's Zachariah Hughes about how the 2018 Iditarod shaped up like this and how that chase pack got so bunched up. Also on today's Iditapod, we have a report from KCAW's Katherine Rose about a way for Iditarod fans around the world to get connected to the race: fantasy mushing.
