4th Annual Tour de Gravelly

Ennis, MT 59729, USA



Thanks for your interest in the Greater Yellowstone Adventure Series (GYAS) races.  We have not cancelled the GYAS events for 2020.  However, we have temporarily closed our registration for all the races until the situation becomes more clear.  Montana is under Phase One of its opening which limits group sizes to no more than 10 people.  If the Governor decides to go to Phase Two, groups of up to 50 people will be allowed.  At that time, we will try to obtain race permits to allow some or all of our races to be held in a limited format as originally scheduled from July 16 to July 26.  There is no guarantee that we can obtain permits under Phase Two, but it’s our intent to try and do so.


Please sign up for our newsletter to keep in the loop on this situation.  Go to our race website – www.themadisonmarathon.com – and click on the newsletter ‘Stay in the Loop’ link to get on the mailing list.  Thank you.


Stay Happy, Healthy, and Always Keep Running Forward.

Greater Yellowstone Adventure Series

 Montana's newest and coolest gravel road cycling race

Okay, we got our first three done.  We're growing, getting good at this, and we are definitely onto something big. The net gain on this route is over 6,000 feet. That's one hell of an uphill. The net drop is over 4,800 feet so after a huge uphill you get a white-knuckle downhill.

Get ready for a cycling adventure of a lifetime.

Beginning in 2020, there will be a choice of two routes for the Tour de Gravelly. These are ‘The Beast’ which is the original route of the first three years, and ‘The Animal’ which is about 20 miles shorter than the original but also goes up and over the Gravelly Range Road. Both races start at the same time and at the same place (6:30 AM at Lion’s Club Park in Ennis). Both races have the same finish line (Vigilante Station in the Ruby Valley). The routes are the same for the first 28 or so miles. The net elevation gain for The Beast is just over 6,000 feet. The net gain for The Animal is probably closer to 5,000 feet net gain though this has not yet been adequately measured nor has the total mileage – 35 miles is an estimate at this time.

These Ain’t No Pansy Ass City Races

The Greater Yellowstone Adventure Series (GYAS) slogan lives up to its reputation with this race. It’s basically all uphill, and then there's one hell of a downhill. There will be water jugs at roughly five mile increments along the route. There will likely be huge gaps between yourself and other cyclists. There will be roving aid stations – volunteers in trucks – covering as much ground as possible, but we can’t be everywhere at the same time.

If you’re the type of cyclists that needs a very defined and detailed agenda as well as support crews, this might not yet be the race for you. We’re just in year four and are still working things out. But if you want to join the fun and break some new ground with us, please do. The more, the merrier. Someone has to go first and you will be more than welcome to be part of the group. 

The race packets have the details as well as a route map. 

Suffice to say, this is a Bucket List kind of gravel road cycling race.  Our vision is that it will be a national destination race. The route is just too damn beautiful and challenging for it not to be.

Come see for yourself!
