It doesn't really translate well because an important aspect of cross-country skiing is the technique, and without proper technique you dispel too much energy to be competitive.
In 1996, Nike decided on a sports experiment / PR stunt - it would pay for two Kenyan long distance runners, Philip Kimely Boit and Henry Bitok, to train in cross-country skiing for the 1998 Winter Olympics in Nagano, Japan. The two Kenyans have never skiied before in their lives - heck, they've never even seen snow until they arrived in Finland to train.
Bitok never qualified for the race, but Boit did. He cross-country skiied in the 10-kilometer classic in Nagano ... and came in dead last. The awards ceremony for the race had to be delayed because the winner, Norwegian cross-country skier and legend in the sport Bjørn Dæhlie, insisted on waiting 20 minutes for Boit to cross the finish line so he could cheer Boit on!
It will be interesting to see what he will come up with as all of the current podcast apps IMO leave a lot to be desired. Also interesting considering Apple resently released a podcasting app.
