Old Man Winter Rally & Ride
An awesome combination of fast pavement and rolling gravel roads. You’ll roll through Crane Hollow and other classic Boulder County mixed terrain. A road bike (with wide tires) or a cyclocross/gravel bike will be the best choice for this course. Sign up for the Run/Bike Combo and take on the 5.4 mile run before you ride the 50km course!
We’re switching up the 100km course this year adding beautiful views of the Twin Peaks and Carter Lake. You will ride north for a new gravel section and then a roll through a loop by Carter Lake. This means less overall elevation gain and no off-the-bike section. A cyclocross bike or road bike will be your best bet for this course.
Our event benefits Can’d Aid and funds will go towards rebuilding your favorite flood-damaged hiking and biking trails
