In the four-year history of the Durham Warriors Survival Challenge, at least one former competitor on the CBS reality show, “Survivor,” always made it to the final three.

That all changed a few weeks ago as Ryan Kaiser of Bloomington, Ill., Rachel Presby of Hollis and Maria Bruno of New Brunswick, N.J., made it out of the tribal councils as the top three. Then, with little drama, Kaiser won all eight votes to become the 2016 Durham Warriors Survival Challenge winner.

The June 23-26 event, hosted by former “Survivor” champion Bob Crowley and his wife, Peggy, former South Portland residents, is held in the woods around the Crowleys’ Maine Forest Yurts in Durham. Proceeds from the event benefit military and service groups, who get to spend nights in the Cowleys’ yurts. While this year’s total amount of money raised wasn’t available, Peggy Crowley said the  event generated $14,000 last year. Approximately 70 volunteers donated their time.

Mike Allbright, an event volunteer, said that Kaiser was a clear winner.

“He was just extremely social and he did very well physically,” Allbright said. “He won three of the individual immunity challenges.”

The final 11 competitors had merged from the original four tribes into a tribe called Chloa, and then individual challenges began.

The Crowleys set up each of the three eight-person teams with two former “Survivor” contestants. Team Opa (purple) had two-time contestant Spencer Bledsoe of Chicago (Cagayan, Cambodia) and Twiler Tanner of Bonnell, Fla. (Vanuata). Team Sawa (green) featured Kyle Jason of Detroit (Kaôh R?ng) and Kelly Shinn of Phoenix (Nicaragua), while Team Ahaso (red) had Matt Bischoff of Cincinnati (Caramoan) and Nina Acosta of Clovia, Calif. (One World). Blesdoe was the last former “Survivor” competitor voted out of the individual competition.

Team Opa started fast in the first full day of competition, winning the first two challenges. Big Derek Meredith of West Virginia, who missed the cut for this year’s “Survivor: Kaôh R?ng,” and the much smaller Bledsoe combined their talents to pull Team Opa through in the barrel challenge. Samantha Belanger of Lisbon also competed for Team Opa.

In the barrel game, contestants try to move four barrels 50 feet along two planks – without touching the ground, Bob Crowley said. The first team to get its eight people across without touching the ground wins.

“We try to do as much new stuff that we can every year,” he said. “A lot of it comes from ‘Survivor,’ but we try to add a new twist.”

Belanger, 21, is a production technician for FHC of Bowdoin, which makes medical and surgical devices used in brain surgery. Like Meredith, Belanger also applied without success to “Survivor: Kaôh R?ng.” Soon afterward, she reached out to the Crowleys and was chosen to compete in the Durham Warriors Survival Challenge.

“This is wonderful,” Belanger said during a break between the barrel and dominoes challenges. “It’s fun, I’m getting to meet a whole bunch of new people and I get to be out in the wilderness.”

Belanger was in the middle of Team Opa during the barrel challenge.

“I helped move the barrels, and I helped weigh down the board for the guy who was in the back,” she said.

Following an initital get-together at the Crowley farm, across Auburn/Pownal Road from Maine Forest Yurts, the tribes all moved to the competition area and tented out on Thursday, Friday and Saturday nights. The final Tribal Council is always on Sunday, and the winner is announced, followed by a banquet.

Other Maine contestants included John Hamer of Winterport for Team Ahaso and Alex MacDonald of Saco for Team Sawa.
