KRASNAYA POLYANA, Russia -- Quickly turning into an unexpected medal contender, Matthias Mayer of Austria led the second downhill training session Friday on the Olympic course.

The 23-year-old Mayer clocked 2 minutes, 6.51 seconds, slightly quicker than Bode Miller's leading time from a day earlier, as the course was harder and a bit faster. Mayer has never finished better than fifth in a World Cup downhill, but was third in Thursday's training in perfect conditions.

Former overall World Cup winner Carlo Janka of Switzerland was second, 0.27 seconds behind, but he missed a gate. Aksel Lund Svindal of Norway was third, 0.55 behind, with Miller sixth, 0.64 behind.

Erik Guay of Mont-Tremblant, Que., was the top Canadian in 15th place, 1.75 seconds behind in 2:08.26.

Manual Osborne-Paradis of Invermere, B.C., was 20th, finishing 2.24 seconds behind Mayer's pace while Calgary's Jan Hudec was 4.22 seconds behind in 38th spot. Morgan Priddy of Whistler, B.C. did not start.

A third and final training session is scheduled for Saturday, with the race Sunday opening the medal events for Alpine skiing.
