Shawn Decareaux, Owner / Tour Leader / Caterer

A friend encouraged me to begin riding many years ago. Though I was reluctant, I soon found cycling gives me the freedom to see the beauty of nature. Traveling down backcountry roads, I experience new adventures that are thrilling to me. I wake up and think where my bike will take me today? I love encouraging people to come along for the ride. Raised in a large family, cooking with large pots and portions are natural for me. Sharing good food feeds my passion for connecting with new friends and advances the excitement and adventure of cycling, which brings out the best in people. I started BIKEternity because sharing good food and good friends are the elements of a successful ride.

Sandra Corso
Sandra Corso, Tour Leader
I am Sandra Corso. I was born and raised in Rio de Janeiro, Brazil. Like most “Cariocas” (natives of Rio), I fell in love with nature at a very young age. Because Rio is surrounded by beautiful tropical beaches, islands, rainforest and mountains, it inspires many people with a deep desire to enjoy nature. As an adult, I  lived in the U.S. for more than 35 years, working as a Seismic Analyst at the University of Washington, and leading 2 to 30-day mountaineering, climbing and backpacking trips for a number of outdoor organizations. I have been guiding Wilderness trips, bike touring as well as Bikepacking tours in the Sierras, Alaska, North Cascades, Canadian and Colorado Rockies, South America and all of the National Parks of the West, for over 25 years. When not guiding and instructing, I enjoy Bikepacking as well as exploring and researching about adventure destinations all over the world.

Kalyana Algrabeli, Tour Leader

While currently living in Portland, Oregon, Kalyana spent all her youth’s summers visiting her grandparents in Bar Harbor, and the carriage trails and tide pools of Acadia National Park are very dear to her heart. Some of her first experiences of the freedom of the bicycle were had on those hard packed dirt roads. She returned in 2015 to visit her family and become a Sea Kayak Guide— becoming acquainted with Mount Desert Island’s granite coastline from the water side as well.
Bike touring has been a formative and large part of her life.  Beginning with a first daring solo trip from Canada to Mexico on the Pacific Coast, she’s gone on to lead people on tours in Death Valley, the Cascades, Cuba, Hawaii, Alaska, and  across the US on the TransAmerican Trail. She delights in curating the very best, most fun experiences on tour and sharing the freedom of the open road with other adventurers. Meeting people from all walks of life and sharing the experience of a bike-powered journey together is her most joyful life’s work.
She is in so much gratitude for all the amazing places she gets to visit leading tours, and this homecoming to Acadia is feeling especially sweet. Additionally she has been studying yoga for many years and has been teaching for the last few. She believes that yoga and cycling go together in incredibly complimentary ways to optimize mind, body and spirit health on tour. This Acadia Sea-Breezes Yoga Bike Tour combines her two greatest passions in one of her favorite places and she cannot wait to share this special journey with you!


Charlie Livermore, Cycling Coach

My passion for cycling began in 1984 after watching Team USA in the LA Olympic Games. My coaching career evolved from racing and Team management. Racing in the amateur ranks for 20 years gave me a solid understanding of the demands of the sport, but it’s the access I’ve had to Pro Cycling that has taught how to be a coach. My first opportunity to work in Pro Cycling was in 1989 with the Wheaties Schwinn Cycling Team. Then I had three great years working with Chris Carmichael at USA cycling, three years with the Coors Lite Cycling Team, and finally seven years at the helm of the Volvo/Cannondale Pro MTB Team.


In 2004, I founded and operated a cycling performance center in Northern California. In 2006 I co-founded Continuum Sports, the management company of the BMC Pro Cycling Team, which I am still involved with today. I started coaching with CTS in 2011. I’ve had and continued to have access to the best coaches and cyclists in the world, and now I have the privilege of using 30 years of knowledge and experience to coach cyclists here at Carmichael Training Systems. Of all of the positions I’ve held in cycling, none gives me more pleasure than coaching. The ability to change people’s lives gives me great satisfaction.


Beth Ann Hinnant, Tour Leader

I am Beth Ann Hinnant. I am blessed to live in Staunton Virginia in the beautiful Shenandoah Valley. I am a retired computer programmer analyst and got into touring quite by accident. I was an endurance cyclist and signed up for a tour just to slow down for a week. The touring bug bit me hard, and I hung up my "a century every weekend" lifestyle. My knees definitely thank me for that transition.

I have done dozens of bikepacking tours all over the USA & parts of Europe and Canada. I have lead tours across New York State, and in Louisiana, Texas, Georgia, South Carolina, Michigan, and Virginia. My very favorite was the Southern Tier. I started out solo but met 2 beautiful people along the way, and we became cycling buddies. It was nice not to cross the Chihuahuan Desert alone! Touring allows me to meet incredible people and explore small-town America at a slow, casual pace. Biking is my life, and I love to tour and will ride just about anywhere. I love to laugh, with sarcasm and deadpan humor being a specialty. Beth Ann-isms are created regularly. When I'm not leading tours, I work for USA Cycling as a race official. I also work for UPS as a driver helper during the holiday peak season.
