Go Fat Biking in Boulder
Crunching down a snow-packed trail through a hushed and stunning wintry landscape on a fat-tire bike (while your fair-weather buddies are stuck inside) will have you feeling like a superhero. The giant, cushy, nubby tires on fat bikes make it all possible — even in heavy snow and icy conditions (but all year-round, really). If you haven't tried it, it's a must. And if you have tried it, you'll love Boulder's trails.
Anything that helps Boulderites get outside regardless of weather gets a big thumbs-up from this outdoorsy town, so there are a growing number of ways to fat bike here.
Where to Rent
Are you a mountain biker ready to try fat biking, or maybe an experienced fat biker ready to see if Boulder's trails live up to the hype? Here's where to rent your own fat bikes.
Located downtown, U Bikes is staffed with longtime bike experts and enthusiasts. Rent on their website (just scroll down to "type of bike" and click on "Fat Bike").
Where to Ride
These in-town paths and mountain biking trails are great for fat bikes in winter, or any time of year, really.
The 3-mile Sage Trail from North Boulder's Boulder Valley Ranch is relatively flat but is a sight to see in winter, with sweeping vistas.
A sidelong view of the dramatically slanting Flatirons is one of the highlights of this large network of trails south of Boulder. Doudy Draw Trail itself is 2.2 miles, but 18 miles of mostly singletrack connect to it.
This 5.2-mile out and back is atop dirt road and is good if you don't have a lot of time since it starts at the base of Boulder Canyon near downtown.
Near the town of Lyons, about 30 minutes from Boulder, is this beloved network of singletrack that's a delight to ride in winter on a fat bike. Keep an eye out for wildlife, particularly wild turkeys.
