There’s still time to get training support with the mobile app Unleesh (, an experiential learning app that allows O2X to deliver daily workouts designed to maximize performance on the mountain. Unleesh provides easy-to-follow instructions with images accompanying each exercise in a given workout. To receive the training plan, download Unleesh on iOS or Android by searching “O2X.” Those who prefer the good old map-and-compass style to mobile apps can sign up for the O2X email list and receive a PDF copy of a 33-week workout.

“The Unleesh app will help users establish a fitness baseline and structure their workouts with the perfect blend of duration, intensity and recovery right up to race day,” said O2X co-founder Adam La Reau. “It’s like having a personal coach training you to peak for O2X events – you don’t have to worry about going too hard or too easy, too long or too short – with the Unleesh training app, you’re in good hands.”

Boston band Element 78 will headline the post-race celebration, as cash and prizes for category winners are given away throughout the night – including the “O2X Rise Higher Award” which will be awarded for the most inspiring racer, as nominated by racers and spectators prior to the event. Climbing pioneer and featured speaker Arno Ilgner will address methods of overcoming obstacles in both life and athletics “The Warrior’s Way.”

Sunday River’s South Ridge Lodge will be home to a vibrant weekend-long “BaseCamp,” offering a variety of local foods and beverages. There will also be limited on-site camping, training-and-performance exhibits, slack lines and bouldering walls and a farmer’s market-inspired gathering of local fare. Come Friday for dinner around a blazing bonfire and pitch a tent. Breakfast will be served the morning of the race and food and drinks during the rest of the day.

The dynamic range of sponsors, partners and local supporters represented at BaseCamp include Juti Organics, Defense Mobile, Delta Dental, CamelBak and Maine Adaptive Sports and Recreation. There will also be activities with local non-profits supporting the environment and a creative and fun kids race.
