SEGUIN ISLAND – A group of servicemen, including Navy SEALs, will participate in a 69.2-mile triathlon as part of Camp Sunshine’s 2018 Stone Coast Challenge.

The challenge, along with the Landing Party and Meet the SEALs Gala, is part of a continuing effort to raise money to send military families with children with life-threatening illnesses to attend Camp Sunshine in Casco.

The Stone Coast Challenge is designed to resemble the ups and downs that families with children with life-threatening illnesses face every day. The challenge will begin with a three-mile, open-ocean swim from Seguin Island to Popham Beach, a 60-mile bike ride from Popham Beach to Crescent Beach in Cape Elizabeth, and will finish with a 10K run in Cape Elizabeth.

The subsequent Landing Party will be an opportunity for the general public to gather at Fort Williams Park in Cape Elizabeth to see the participants finish the triathlon.

That evening’s Meet the SEALs Gala is a formal reception with the participating SEALs and special dignitaries at Ocean Gateway in Portland.

Since 2014, Navy SEALs and other servicemen have been competing in physically daunting tasks for Camp Sunshine. The SEALs have participated in a 13-mile swim across Sebago Lake (2014), a reverse triathlon that begin at the top of Mt. Washington (2015), a combination triathlon around Sebago Lake (2016), a 10-mile open ocean swim around California’s Coronado Island (2017), and most recently a 26.2 mile paddle around Coronado Island (2018).
