The Chaski Marathon & Relay

Did your fall marathon get cancelled? Running a virtual race and looking for another medal? Welcome to the Chaski Marathon and Relay!​

You can run/jog/walk on the road, on a track, on a treadmill, or even around your living room if that's what you have available.


Mass Start: 9am ET on Saturday, September 12, 2020


Choose your start: Run at your convenience during the week of ​September 6 - 12

We miss the pre-race hype as much as you do and that's why we want to try to recreate that feeling with a mass start time across time-zones featuring a pre-race (virtual) pump up zone. We'll have some speakers, warmup exercises, and words of encouragement to get you ready to go!

Of course, we also recognize the value of being able to run on your own schedule. So, we're also giving you the option of racing any time during the week leading up to the race!


First, make sure you register! (If you're registering for the relay, make sure you include your team name when you register)

Next, go out and train your butt off - and don't forget to post and use #ChaskiChallengeMarathon so we can highlight your hard work!

Then comes race week. As mentioned above, you have two options. You can either participate in our mass start at 9am on Saturday September 12 OR you can run your marathon any time in the week leading up to the race.

How does the running actually work?

Full Marathon

Simply go out and run your 26.2 miles (42.2km) on a measured course, treadmill, or using a GPS watch to track distance. Make sure you obey local recommendations and restrictions regarding exercise and group gatherings.

Marathon Relay

Relay teams will be composed of 3 runners of the same gender. Each runner will chose a relay leg of either 12 miles, 8 miles, or 6.2 miles. You do NOT have to run in the same physical space as your teammates, nor do you have to run at the same exact time (or in exact succession). Simply submit your individual times and the team with the lowest total times will be the winner.


Once you've finished, give yourself a pat on the back, and then submit your result via our registration system. 

Finally, submit your time to our results database (and give yourself a pat on the back!) Note - in order to qualify for prizes, you must submit GPS data along with your time.

The best part? You can tune in and follow our live webcast of the professional marathon relay the same evening. Get ready for a great show!

What do I get? 

We want to make these events as accessible to the running world as possible and we know that many people want to have a goal race on the calendar but can't afford to pay to enter.

Thus, our races are and always will be free to register, participate, be part of the community, receive a print-at-home race number, have your results posted on our website, and even win awesome prizes!

If you'd like any of the "extras" you might be used to at a normal race, like a t-shirt, awesome medal, high quality race number, or other swag, we're selling those for folks who want them.

Note - for the marathon and relay, all profits will go to the Brave Like Gabe Foundation.

Awards and Prizes

Marathon and Relay will feature prizes from our sponsors for top times as well as prizes for best team name

Prizes will be announced in early August
