The Cadillac Challenge Century Ride:
The Cadillac Challenge is a superb day of bicycling on beautiful Mt. Desert Island. Riders will cycle through some of the most spectacular fall foliage scenery that Maine has to offer including mountains, the Atlantic Ocean, Somes Sound, lakes, forests, wetlands, harbor towns, abundant wildlife, and much more. Two ride options of 68 and 100 miles are available to suit varying degrees of fortitude and both include the spectacular roads and scenery of Acadia National Park.
In its thirtieth year, "The Cadillac Challenge Century" features 6,950' of climbing and travels just about every road on Mt. Desert Island. After a 87 mile warm-up, you’ll begin the final 3.5 mile, 1,000' climb up Cadillac Mountain. The summit at 1,530’ is the highest point on the eastern coast offering an eagle’s eye view of the Atlantic Ocean, Frenchman’s Bay, Mount Desert Island, and the mainland beyond. After all the day’s efforts you’ll enjoy the great downhill run to the finish with only one short uphill in the last eight miles. For those that prefer a shorter ride the metric (plus) century route features 5,551’ of climbing over 72 miles and includes the Cadillac Mountain climb.
You also won't have to strong arm friends and coworkers for ride pledges or pay an exorbitant entry fee just to go on a bike ride. The Cadillac Challenge is free of charge to all who wish to ride! (However, only if you wish, donations to help out with ride expenses will be cheerfully accepted.)
Please note that Acadia National Park policy dictates that bicyclists pay an Entrance Fee to Acadia National Park for their use of the Park.
Details for Riders and support vehicles:
- The route is marked in orange on the pavement, except that in ANP, there are wooden directional signs. (No painter signs in ANP.)
- The Bar Harbor/Mount Desert Police will be at a few critical intersections going through Bar Harbor at the start. Don't forget to say Thanks.
- There may be cruise ships in 2021. If there are, we will be in contact with them so that we can be aware of each other, especially on Cadillac.
- The automobile registration will probably be in effect in 2021 and beyond. Again, that doesn’t affect cyclists except that we may have to wait in line with the cars at the Sand Beach and Cadillac entrances.
