Team GB athletes Andrew Young and Callum Smith have conceded that they struggled with the warm Sochi conditions while competing in the men's cross-country skiing.
Young was the fastest Briton in the 15km classic as he came 37th in a time of 41:29.6.
Smith completed his Olympic campaign with a 67th-place finish, and has revealed that the unfamiliar hot skiing conditions in Russia even forced him to change his race attire.
"It is hard quite hard, I am wearing a T-shirt rather than a race suit," he told reporters. "It is not often you race in 13 degrees or whatever it is. It does make it a little bit harder.
"The tracks are soft. You just feel really warm. We took on drinks every lap, which we wouldn't normally do in a 15km."
Young added: "You are just dying the whole way around. I had four drink stations today and normally in a 15km I don't drink at all. It was hard. I don't how I managed to ski so fast. The wax technicians did a phenomenal job – that helped a lot. I just felt really good."
Briton's Andrew Musgrave also competed in the event, finishing 44th.
