Routes » Grand Loop



The “Grand Loop” covers 360 miles of remote desert terrain between Moab and Grand Junction. The loop was officially finished in 1995 with the mapping of the Paradox Trail, the final link to the loop. The two other links are Kokopelli’s Trail (finished in 1989) and the Tabeguache Trail.

All three of these trails can be ridden themselves, or you can challenge them all. Some like to challenge themselves to ride the loop as quickly as possible. This page chronicles those efforts (see: Racing the Grand Loop).

Route Info

Not much singletrack was constructed for the Grand Loop. A few key pieces were needed to link existing dirt roads, and those were built by COPMOBA. But don’t let the lack of singletrack fool you — this is a rough and challenging ride.

Many of the 4×4 roads are technical enough to force dismounts and hiking. You will hike your bike, period. But the solitude, scenery and adventure afforded are unmatched, especially being so nearby to frequently ridden (Moab) trails and roads.


There are few services on the route. If you follow the new (2005+) version of the Paradox Trail, there are actually no services. The Bedrock alternate on the Paradox takes you to the tiny town of Bedrock, where a small store with limited hours offers limited resupply. Nucla is also ~10 miles off route, and has cafes and a more substantial grocery store.


Picking a good time to ride the Grand Loop is difficult. Snow typically lingers until late May or early June on the upper reaches of the Tabeguache Trail. Yet Kokopelli’s trail covers many a mile of low desert terrain that would be preferrable to ride in April, not June! Fall might be a tempting option, but key water sources may be dry, and lack of daylight is an issue.

Historically, most successful Grand Loop traverses have been in early June, but they have also involved a fair bit of night riding through the lower sections. It’s best to watch the conditions, particularly the snow levels. Some years it is possible to snipe a GL ride in May. Check the Columbine Pass snotel site for the latest conditions on the Uncompahgre Plateau.

Racing the Grand Loop

There is no set time or organized race on the Grand Loop. However, this page will serve to record all successful Grand Loop rides, and will rank them by time. In the true spirit of self-supported mountain biking, you are encouraged to ride the route whenever you see fit and report your time (and your experiences on the trail!). If you want to be on the course with other riders, see the Ultra Racing forum to coordinate with others. There is one such thread already.

Hey Scott,
Just a little surfing and found this page. Great job setting this up. Just to let you know, my time for 2008 was 4:18:30.(I had to stay out there to savor the adventure;). I really need to write it up.

Thanks Dave. I added your time. Congrats on pushing through all that snow up there. Please post up when (not if) you finish the writeup.

Added Jim L’s 2011 finish time. Thanks for keeping the Grand Loop fire alive, Jim!

A Grand Loop primer
Back in 1994 I was joined by 6 other mountain bikers on the first known mountain bike ride of the
Grand Loop – an abbreviated version of the classic 360 mile race course. Our group covered 243 miles in 6 days. Our goal was to explore and soak it all in. We used little known shortcuts and variations to tie the
route together. We saw more bears than other mt. bikers. The ride was detailed in “Colorado Paradox” written by Fred Matheny in the July.1995 issue of “Bicycling” magazine. It is truly a one-of-a- kind tour.
I’m glad to see the spirit of long-distance riding is alive and well.

Wow, Bill, I can only imagine the adventure you must have had out there! Thanks for the post. The spirit still loves on, no doubt. Just last week a couple of ladies scorched the full route in under 4 days (I just added them to the completions list)!

Very good post. I definitely appreciate this website.
Keeep it up!

Hey, thanks for setting up a page with all this info! I just wanted to mention that the external links at the bottom of the page are all broken/outdated in case you were unaware.

As a heads up to all. The Paradox Trail Reroute has been completed adding another six miles to an already difficult course. The reroute did provide two big pluses. There is now about five miles of really nice riding single track included in the reroute AND the course brings riders to the edge of Nucla. The full PT course and downloads can be found at :

Thanks for all your hard work Paul, the new re-route was a hoot! Here’s my when (not if) 2018 ride report for the course taking the new Paradox Route: My time was 4:21:57.
