BRIDGTON — Registration is now open for Maine’s toughest century bike ride, the Loon Echo Trek, set for Saturday, Sept. 19.

Loon Echo Trek will also offer 25 to 100 mile rides, hike-bike combo, plus gentler, family-friendly.

New this year, a $15 early bird discount is available to all who register before midnight Sunday, July 19.

The annual tradition attracts nature-lovers and athletes from all over New England to the Western Lakes region each fall, often during peek foliage time. The event features Maine’s toughest century bicycle ride, with 100 miles of terrain over roadways and through national forests. Other gentler 75-, 50-, and 25-mile biking options are popular, as well as the hike-bike combo and family-friendly hikes up Pleasant Mountain in Bridgton. All routes promise breath-taking scenery and rest stops with refreshments and support.

New this year, the post-Trek afternoon celebration at the base of Shawnee Peak will feature Crooked River Rought Cut, a local acoustic band, and yummy food inspired by the vista.

The event supports the Loon Echo Land Trust’s mission of conserving and caring for land, including southern Maine’s highest mountain. To that end, participants are encouraged to get pledges of support, with top fundraisers earning an overnight yurt stay or a 2015 season passes at Maine’s top skiing destinations, among other prizes.
