ST. CROIX FALLS, Wis. (AP) -- Madison endurance runner Jason Dorgan is planning to run through Wisconsin on the Ice Age National Scenic Trail.
Starting tomorrow in St. Croix Falls, the 41-year-old will attempt to cover 1079 miles in 23 days.
That's roughly the equivalent of two marathons, every day, for about three weeks.
In 2005, he covered 135 miles at Death Valley in just under 38 hours to finish 15th in the notorious Badwater Ultramarathon.
He says the Ice Age Trail run is his next challenge.
He says he was looking for something new.
He's also raising money for and drawing attention to the trail.
It is a snaking combination of narrow footpaths and paved roads marking the last encroachment of glaciers on the Badger State.
Two of his longtime friends and fellow ultramarathoners, Tom Bunk and Robert Wehner, will take turns as his crew.
One of them will drive to meet him at road crossings and help get Dorgan the 5000 to 6000 calories he needs to consume every day.
