From Decider:

Though it seems Sam has the edge — after he triumphantly lifts a big bolder from the ground and onto a stone plinth — Graham slowly sneaks into the lead. By the end of the episode, Sam is the one who has to strip down and take the plunge. Graham McTavish is still thrilled about it.
“All I can say is that it was such a sweet moment when I was able to witness him running in the freezing rain and wind into the North Atlantic Ocean,” McTavish told Decider. “So I literally fell to my knees with joy. I know this might seem a little petty, but…”
“Very petty,” Sam Heughan said, interrupting. “Childish. I mean, the amount of jubilation and then and then also, like, as we were driving to the skinny dipping, I mean, he just couldn’t contain himself.”
McTavish said, “What was so great, we had such great weather and on the day he had to do that, it was terrible. It’s not that I delight in watching him suffer like that, but by this point, I had been put through quite a lot.”
