Distances: 63, 127 miles
Difficulty: Difficult terrain with longer, steeper hills

Come and enjoy miles on miles of gravel roads around beautiful Wellsboro Pennsylvania, home of the PA Grand Canyon! We have another fresh course for 2025, a few roads overlap from previous years courses and we are changing the direction of travel on some favorite roads from years prior. This route, like every year, is a BEAST!

The Full MAMMOTH course is 137 miles and roughly 13,000 ft.+ of elevation gain to challenge even the most advanced riders. Those of you that choose to attempt the Full MAMMOTH will ride two separate non overlapping loops. Both loops begin and end at the same place in downtown Wellsboro. The morning loop is 67 miles in length and afternoon is 70 miles. 

Half MAMMOTH riders will just ride the 67 mile morning loop along with the Full MAMMOTH riders but will be done riding after the morning loop.

Free parking is available within a few hundred feet of the event center. If you stay at the Hotels located in downtown Wellsboro you will only be about a 2 minute bicycle ride from the Start/Mid/Finish.

Roughly halfway through each loop there will be an absolute banger of an aid station. We work with local businesses to provide hearty food at aid stations, as well as the essentials. The morning aid stop is included with all registrations. The afternoon stop is included with only Full MAMMOTH Registrations.

(Please keep in mind that there will be a support vehicle patrolling the course as well as sweep riders bringing up the rear but we highly recommend that you carry what you need for approx. 35 mile stretches)

We try our best to mark this monster route but the weather the previous days to the event really can dictate how well it is marked, but the safest option is to use a bicycle computer with navigation or a phone app like Komoot or RWGPS for navigation. GPX file will be sen
