Pro Ultrarunner Coree Woltering on Training, Mindset, and Showing Up

Coree Woltering has been running for 29 years. At 36, he's a professional ultrarunner based in Maine, where he trains year-round without a treadmill, currently building toward Western States 100 and the Mammoth 200 after coming back from injury. 

We sat down with Coree to talk about his perfect run, the mindset that gets him through hard days, how his approach to the sport has evolved, and the Smartwool® socks and apparel that travel with him from Maine to mountain races around the world. 

What Does Coree Woltering's Perfect Run Look Like? 

Q: Describe your perfect run, including terrain, weather, mindset, and location. 

"First week of October in Northern Maine or Quebec, on a dirt road lined with trees as the leaves are changing. The red, orange, and yellow leaves make it look like something out of a photo or painting. If you're lucky, you just need a light long sleeve and shorts. Tyler Childers and Slipknot on the headphones, and hopefully a nice cup of coffee waiting at the end." 

For Coree, the perfect run is shaped by the New England fall: dirt roads, peak foliage, mild temperatures, and a soundtrack that can keep up the pace. It's the kind of weather where a light Smartwool® Merino base layer does its best work. 

What Keeps a Pro Ultrarunner Going on Hard Days? 

Q: What keeps you coming back on hard days? 

"The fact that I still believe good days are ahead. It would be easy to say, 'I've done enough,' but I still believe the best is yet to come. I've built the mental tools to work through almost any situation out on the trail, and in life, so a rough patch now doesn't mean it won't get better in five minutes. It doesn't have to be perfect. It doesn't have to be great. You just have to show up." 

Coree's philosophy, just show up, is the kind of mantra that defines ultra-distance success. He credits decades of trail time with giving him the tools to ride out low moments, knowing they're temporary and all a part of the process.  

How Has Coree Woltering's Approach to Running Evolved? 

Q: How has your approach to running changed over the years? 

"36-year-old Coree is a much different athlete than 7-year-old Coree. There have been periods of competing at the highest level and times of using running as my social outlet. Right now I'm coming back from injury, so my mindset is simple: do what you can, when you can, no stress. Running has taken me around the world multiple times. Currently I'm enjoying the social aspect, and all the coffee shops along the way, as I train for Western States 100 and Mammoth 200."

After 29 years in the sport,Coree’s identity as a runner has gone through a lot of changes,from competing at the highest level to using running as a social outlet. His current chapter, coming back from injury while building toward two of the toughest ultras in North America, reflects a more sustainable, joy-first approach.

The Gear That Travels With Him 

Q: Why do you train in Smartwool®? 

"Honestly, easy question: Smartwool works. From socks to base layers to the new run gear, it works. I live in Maine and don't own a treadmill. It's cold. Between proven performance, comfort, and fun colors, it's gear I can count on." 

Training year-round in Maine without a treadmill means dealing with conditions most runners would call extreme. Merino wool is naturally thermoregulating, helps resist odor for long wear, and offers moisture management for dry-feeling comfort, which is part of why it's become a fabric of choice for endurance athletes. 

Built for Variable Conditions 

Q: How are you liking the new Intraknit™ Active gear? 

"Game changer. I tend to play in conditions that change quickly. It keeps me warm on cool, windy days and still functions on warmer, sunny ones. If I'm starting warm and sunny at the base of a mountain but expecting cool fog near the summit, I'm happy I can keep the same layer on the whole way." 

The Intraknit™ Active collection uses body-mapped knit construction that places lighter, naturally breathable zones where you produce the most heat and warmer. For mountain runners like Coree, that means fewer layer changes mid-run.
