Coree Woltering

Coree Woltering, who’s known by some as one of the #cornfieldcowboys, was born and raised in Ottawa, Illinois. He began his running career in the 400m and 800m distances and had his sights on becoming a professional triathlete, qualifying for the Ironman 70.3 World Championships twice. But before long, he discovered ultrarunning and became mesmerized by the idea of running 100 miles in the mountains.

Coree took his frontier to the next level in 2015, where he won every trail 50k he signed up for that year. In 2016, he averaged a 6:36 per mile to win the Tunnel Hill 50 Mile. At 30 years old, he set the fastest known time (FKT) in 1,200-mile Ice Age Trail in Wisconsin. And then followed that up with the 349 Mile Pinhoti Trail FKT in 2021. He ended up loving the trail so much that he moved to the south, but eventually relocated to Maine! Coree has finished Western States 100 2 times, HURT 100 Mile, and many other ultra.

When Coree is not running, he is probably sitting on his balcony drinking a cup of coffee, or out on the mountain bike.
