About Jeff Miller & Northwoods Running

I am a life-long runner that started by running cross country in junior high school. I have been training and competing consistently since then. I am passionate about running and helping others stay active and healthy — not just for a race, but for their entire lives.​

I started my business, I M Fitness Training, Inc., in 2018 as a certified one-on-one personal trainer part-time and slowly began working exclusively with runners as a certified ultrarunning coach. I LOVE coaching runners, and in 2020, I began coaching as my full-time job.

I now work with athletes of all types and abilities across the country with a particular focus on ultra marathon runners.​ I have run hundreds of races of varying distances, and I apply what I’ve learned from my successes and failures to my coaching clients, my personal performances, and my public appearances. If you are struggling with injuries, want to up your game, or just want to live healthier, let’s talk and find out if Northwoods Running can help you achieve your goals.​

I am married with two grown kids and two grandchildren. My wife and I love to spend time running, hiking and clearing trail on the Superior Hiking Trail in northern Minnesota. We also enjoy volunteering at races in Minnesota and Wisconsin. Welcome to our running family!
