Banner final


Want to join the madness, but not quite crazy enough to do full or half marathons? We’ve been asked if there was a way shorter distance runners could participate in our fantastic series. Ask and you shall receive! Mainly Marathons is proud to announce a new distance to all of our great events starting in 2015, the 5K!
A 5K is 3.1 miles, or about 1.5 loops on our typical course. This is a great distance to start at if you are interested in endurance running, and these 5Ks will feature everything Mainly Marathons is already famous for! Starting with next year’s Dust Bowl Series, every event will now have a 5K, as well as a Full and a Half marathon. So sign up today and come out and join us!

See you on the course!

You’ve seen them out on the course. They rarely win, but you always see them out there running, and running and running. And sometimes walking.
These events were inspired by and designed for them, and for those who just want to run long and run often.

Whether you want to participate in one marathon, half-marathon, or 5K, pick up a couple of new states in your quest to finish all 50, or you want to take the ultimate challenge and run every race in a series, we encourage you to join us. Walkers are just as welcome as runners: none of our races have a time limit, and you never need to worry about whether you’ll make it before the course support has packed up and gone home. (In fact, we have become famous for celebrating last place in every race with the now-coveted caboose!)

Mainly Marathons puts on a race series like no other, from the unique course setup to the unparalleled spread of food and drinks to fuel you on your journey, all mixed with a sense of fun and family you just won’t find anywhere else.

Check out our schedule to see where we’ll be, then sign up on our simple registration page.
Feel free to send us an email if you have any questions.
