Ultra Series

The UMTR Ultra Series is a series of ultra trail races throughout the upper Midwest.

Series Coordinator: Carl Bliss

Sponsored by: Ultimate Health Chiropractic

Dr. Chad Koterba is not only a chiropractor, but also a certified athletic trainer. His background in sports medicine and chiropractic gives him a unique ability to treat sports injuries, as well as other nerve, muscle, and joint injuries.  He specializes in runners and active individuals by using a comprehensive approach of treating through adjustments, specific stretching and strengthening exercises as well as soft tissue techniques such as myofascial release, Gua Sha tools, and trigger point therapy to relieve muscle tension which can lead to pain and dysfunction.

At Ultimate Health Chiropractic, we are runners, we treat and care for runners, and we get runners! You can see this from our wall of greatness filled with race bibs and medals from numerous patients who have trusted us to get them to the starting line and / or helped them with their recovery post-race. 

As you can imagine, 2021 may look a little different. We are still waiting on dates for a number of races, and it's likely that many events will be postponed or cancelled. But we'd still like to run!
