Ultra trail runner and professional athlete Coree Woltering, of Ottawa, Ill., unofficially broke the record for the Fastest Known Time logged on the Ice Age Trail when he completed the 1,147-mile trail in 21 days, 13 hours and 35 minutes. His time bested the standing record set in 2018 by trail runner and Milwaukee native Annie Weiss. She broke the Ice Age Trail record and clocked her time at 21 days, 18 hours and seven minutes.

Woltering, 30, began the record attempt in the western portion of St. Croix Falls on June 1 and ended in Sturgeon Bay at the Eastern Terminus Ice Age National Scenic Trail marker. He passed through the Weyerhaeuser and New Auburn area back on June 4 and June 5, running down Hwy. 40 by King’s Inn and Salisbury Campground.

“Times are not confirmed yet and Coree will submit tracking data from his Garmin watch for verification,” stated Woltering’s husband and crew chief, Tom Aussem. “Coree made the record attempt successfully by pulling off 165 miles in the final 38 hours on just 20 minutes of sleep.”

Because the Ice Age Trail is segmented across several different trails and terrains, Aussem mapped out cross streets and other checkpoints throughout the three-week adventure to offer assistance where the van he drove would provide food, liquids, bananas, berries, yogurt and Gatorade to replenish Woltering.  

Since the late ‘90s, trail runners have been documenting their fastest trail runs under the moniker “FKT,” which stands for “Fastest Known Time.” The title implies that a person has run or hiked the trail faster than everyone before them. The tradition of FKT was started on the major hiking trails out west. However, in the past decade, a few runners have brought it home to the Ice Age Trail. In 2007, trail runner Jason Dorgan set the first FKT on the trail by running it in 22 days and six hours.

Woltering, who is sponsored by The North Face, and several other big-name companies, and his crew members—Aussem, running pacers, Abe Fisher, Egor Korneev, Joey Miller and photographer Kevin Youngblood—were determined to break the Ice Age Trail record. However, they paired the incredible feat with a fundraiser for Feeding America, a national food bank.

The name of the record-breaking attempt fundraiser is known as “Big Run for Grub,” and Woltering and Aussem have aspirations to raise $50,000 to help feed those in need. As of Tuesday, June 23, they had reached 49 percent of their goal, with $24,695 raised so far.

Woltering unofficially broke the record in a time of 21 days, 13 hours and 35 minutes, which was 4.5 hours ahead of the previous record set in 2018. The ultra trail runner successfully finished the record attempt by running 165 miles in the final 38 hours on just 20 minutes of sleep.
