The Athletic Brewing 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: At your convenience, anytime during the week of ​September 6 - 13

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. ​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, 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.

The Athletic Brewing Chaski Marathon Relay

The Biggest, Most Badass Thing Happening in September


By Athletes, For Athletes

The Details: Elite runners in teams of 3 from around the world will compete simultaneously for prize money on measured short-loop courses, with live commentary, race visualizations, and video updates. Live splits will be updated manually by a team assistant to allow for world-wide live tracking for competitors and fans.


Prize Money: We've committed US$2,000 has been committed in individual team prizes (split equally between men and women), with more expected as sponsorship commitments grow.

Altitude Bonus: We'll have a bonus award of US$500 for the team that registers the best altitude-adjusted time. We want to encourage participation from some of the high-level groups training in the mountains without forcing them to travel!


When: Simultaneous run across time zones Saturday, Sept. 12 / Sunday, Sept. 13


Start times in major cities - Note, women will be given a head start of 12 min 25 sec.

Saturday, Sept 12

15:00 - Los Angeles

18:00 - New York

Sunday, Sept 13

01:00 - London

03:00 - Nairobi

04:00 - Dubai

08:00 - Singapore

09:00 - Tokyo

10:00 - Sydney

Where: You can run ANYWHERE. The above list of cities are simply for timezone help. The competition will be run on 2km, 1km, or 400m loops in the athletes' local area.


Logistics: Each single-gender team will run have three runners complete (in order) a leg of 12 miles (19.3km), 8 miles (12.9km), and 6.2 miles (10km) for 26.2 miles (42.2km) total. Teams do NOT need to run in the same place. The team with the lowest cumulative time will be the winner. Courses must be proven accurate by wheel (verification details to follow) or runners may compete on a standard 400m track. Live splits must be uploaded by a team manager/assistant from each course “lap”. 


Live Coverage and Storytelling: Our goal is to not only create an awesome competition between athletes, but also give fans an exciting, engaging, free broadcast. The broadcast will feature a continuous live-stream with professional commentary, a live visualization app so that both competitors and fans can know exactly what’s happening in the races in real time, and video highlights sent in from around the globe.  Based on the success of the Chaski Challenge in June, we expect an organic media reach of approx. 5-10 million people.


Participation: Anyone will be allowed to enter the elite race; however, only approved teams will be eligible for prize money due to certification of running routes. We reserve the right to deny entry to athletes who have been found guilty of doping violations or have been associated with guilty parties.
