[it's solved: Mirror of Ice by Gary Wright] Years ago, I read a short story in an anthology, (a collection of SF-shorts), which was about ice-racing. A dozen pilots went down a glacier/gletscher mountain, in, I assume, bobsled-like vehicles. They were dare devils, committed to racing, but since this was fairly dangerous, also all kind of crazy. It was probably the authors idea to do a Formula 1-on-ice, but even more spectacular.
I can remember two lines: "They only found the body of XXXX the following Spring, when the ice had melted" and a fictional interview with the winner of the race: Q: "When did you feel you started to lose control?" A: "At the starting line"
The anthology maker could be Gardner Dozois, or Geoffrey/Geoff something or someone else entirely.
Era: definitely before the 80s (1940-1980), but most likely before the seventies, so 1950-1970
Question: what was its name and author?
