There is no doubt, Minnesota is blessed to have many great independently owned running stores – TC Running Company is one of them but the difference at TC Running Company is their unparraled interest and support of local trail and ultra-running. Thank you TC Running Company for your ongoing support! TC Running Company endeavors to meet the needs of a variety of runners including local middle and high school athletes competing in cross country and track & field, parents of student athletes, college runners, post-collegiate, and competitive runners. We’re also the choice of several local running groups such as Lifetime Fitness, ALARC, MDRA, and The Marsh (which include beginners and walkers). Over the years, TC Running has kept its focus honed and effective. And even though we’ve grown a little since we first opened shop, we still have the same product focus, the same great employees, and the great discounts we’ve been known for in the past. Our efforts have always been locally based, and we will stay true to those roots as part of our commitment to quality service and helpful customer relationships. We invite you to stop in today and experience the kind of personal attention and sound running advice that only TC Running can provide. We look forward to meeting you!

Steve has been known to say that he is just a “so-so” runner but a pretty good realtor, we think both of these comments are extremely understated! Steve has been running some pretty good times on the trails over the last couple of years and at the same time has tons of happy customers, many of whom are runners! We like doing business with runners – they are the type of people who follow through. Having sold over 450 homes in last 13 years throughout the Twin Cities and Western Wisconsin – if you are in the market or looking to sell, get to know Steve on the trails and we are sure he will be your guy.

Dr. Ryan Lystad, is a sports medicine chiropractor.  What does this mean to you?  It means if you’re doing an activity involving movement of your body, then he has studied how to help correct dysfunctional movement patterns. It is not only about about pain and how to get you out of pain, but how your movements can be more efficient.

“I am much different than most chiropractors that you have ever met, due to my approach to finding the source of your dysfunction and ultimately your pain. I also have been in the trenches with you. I played professional rugby for 4 years, run ultra races, thrown things, swim, bike, and pick things up and put them down. I am here to help you perform at your best, no matter what the goal.”-Dr. Ryan

More About the Area:
The Zumbro Endurance Run 100MI, 50MI and 17MI trail races take place within the Zumbro River Bottoms Management Unit in Southeastern Minnesota’s Bluff Country – just outside of the tiny village of Theilman, MN approximately 1:45 from Minneapolis – St.Paul, MN.  The races start and finish at the West Assembly / Horse Campground Area.  Generally speaking the Zumbro River Bottoms Management Unit lies within a portion of the Richard J. Dorer Memorial Hardwood Forest – an expansive 1.7 million acre tract of Minnesota hardwood forest on the Northern edge of the Driftless Region which is mainly characterized by its tall bluffs and deeply carved river valleys. This “bluff country” is rugged, hauntingly beautiful and provides the perfect venue for 100, 50 or 17 miles of trail running – while this is certainly not an “easy” trail race it can still be a great choice for your first 100, 50 or 17, that is if you are ready for a good amount of climbing / elevation gain.  This is a laid back, old school, low-key trail race hosted by ultrarunners for ultrarunners.
