Still on the fence? Our amazing and LOONY running community is comprised of the kindest, most supportive, and toughest runners in the world. They make Mainly Marathons events so much fun. Check out these testimonials to hear why so many runners return to Mainly Marathons over and over again!
Thousands of happy runners agree, Mainly Marathons is simply the best marathon series on the planet!
If running with us isn’t Loony enough, we have a “Double Down” option to run two races in one day and to earn even more medals!
After the completion of your race, you may run another. BUT the second race will be limited to a 5K or 10K.
AND you may purchase your second race at HALF-PRICE. You may purchase this second race in advance or on race day.
BUT you must be able to complete both races within the 50K time limit and the longer race must be run first.
For those of you thinking “This is MADNESS, why would anyone want to do two?” The answer is, “Yes, this is a tad beyond normal, but our runners are asking for this option, often in an attempt at the Herculean Challenge of finishing the five main races in a state, 5K-50K. For example, they are doing a 5K after their marathon, 10K after a half.”
Contact Daniel@MainlyMarathons.com with any questions.
You’ve seen them 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.
Peace and Toudaloo!
