Routes » Great Divide Mountain Bike Route


The Great Divide Mountain Bike Route was put together by Adventure Cycling in the late nineties. It has since become the definitive route for dirt road bikepacking.

Hi Guys,

Do they have shuttle services to nearby airports from Antelope Wells, NM? My research has told me the nearest airport from the finish is 134 miles away? Any insight would be great.

Hey Eric,
I would suggest you make a contact in Tucson. It’s a 3.5 hour drive away but more flight options at the airport and I would assume after riding the divide, you wouldn’t mind some time in Tucson for a massage and some beers.
I am riding from South to North, starting in late May. Can’t wait. Guess i will see all the Southbound racers somewhere along the route, probably Wyoming.

Good luck

Hey George

I just read you were going to ride the GDMBR northbound. How did it go? My wife and I are planning on starting in Antelope Wells in late May, 2019 and heading to Banff. Would you recommend riding northbound?
