MAMMOTH Endurance Gravel

*Please note that if you register after 3/1/24 we cannot guarantee promotional items of any kind (Shirt, mini junk sack, etc…), all event day food will still be available to you though if you register after this date.

Come and enjoy miles on miles of gravel roads around beautiful Wellsboro Pennsylvania, home of the PA Grand Canyon! We have a fresh new course for 2024, 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 135 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 71 miles in length and afternoon is 64 miles. 

Half MAMMOTH riders will just ride the 71 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. 40 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 sent to the email you use to register a few weeks prior to the event.

Breakfast, Lunch and Dinner will be provided for the Full MAMMOTH riders. (Options are selected in the registration process.) 

Breakfast and Lunch is included for the Half MAMMOTH riders. (Options are selected in the registration process) 

There will be Vegan options available at all meals and aid stations.

All event day check in, meals, and after ride hang out will all be centralized around the tent constructed on the grass lot on the corner of Main St. and Central Ave. next to Beck's Bistro.

*THIS EVENT WILL HAPPEN RAIN OR SHINE.  We DO NOT offer refunds as all the event food and promotional items are paid for and ordered ahead of time. PLEASE CONSIDER ADDING REG INSURANCE OFFERED THROUGH BIKEREG IF YOU ARE WORRIED ABOUT WEATHER ETC. AND GETTING REFUNDED.

Grav-Cas button down cycling tops from Dilly Dally Cycling Apparel, a Mini Junk Sack hand crafted by Tubular Gear are included with all Regs. (*Please note that if you register after 3/1/24 we cannot guarantee promotional items of any kind (Shirt, mini junk sack, etc…), all event day food will still be available to you though if you register after this date.)
