Cadillac Challenge Century

October 06 2019
Mount Desert Island, Maine, USA

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 twenty-seventh 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 68 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, Acadia National Park does charge an entrance fee.

We do cheerfully accept donations to help pay for the food, gasoline for the sag wagon and support staff, and other expenses, but you don't need to donate to ride.k
