Andrew Musgrave became the first British cross-country skier to reach the quarter-finals of an Olympic men's sprint in Rosa Khutor on Tuesday.
The 23-year-old Scot finished 27th in the opening time-trial, enough to earn a place in the knock-out stages which were due to continue later in the day.
Musgrave's position also represented the highest place achieved by a British cross-country skier at any Games, eclipsing Tom Cairney (28th) in Cortina d'Ampezzo in 1956.
Great Britain head coach Roy Young said: "This is an unprecedented achievement and it's amazing for Andrew to be in the quarter-finals.
"In very tricky conditions it's a mighty step forward and his finishing position is within our target looking towards 2018."
Musgrave squeezed in 9.40 seconds behind qualification winner Ola Hattestad but the timings are wiped clean for the quarter-finals, which consist of five heats of six, from which the top two in each advance to the semi-finals.
Despite his achievement Musgrave expressed disappointment with his performance, saying: "It wasn't amazing. I think I'm in very good shape but I didn't ski as well as I should have.
"It's easy on this course to go too fast at the start of the course and I didn't have enough to push with over the top. I lost time over the end of the course which was bad tactics from me.
"Once you get to the quarter-finals it's a different game - 30th or first is the same thing as long as you qualify."
