Four from four……Lina Frener has topped every session she has started across two rounds

Two rounds, four sessions on the clock, four fastest. At Leogang she led timed training by 13.5 s, qualifying by 7.0 and the final by 3.4. At Lenzerheide she has opened timed training 7.5 s clear. The margin shrinks as the runs start to count, but it has not run out.

Only three winners have ever come up from Q2……and two of them came from Lenzerheide last year

Every final is fed by two qualifying runs. Make the cut in Q1 and you go straight through. Miss it and you drop to Q2, the last-chance run, and almost nobody wins from there. Across 26 elite finals in 2025 and 2026, it has happened just three times. Lenzerheide, where two of them came on the same afternoon, returns this week.

The race where Hemstreet beat Bruni 15 times

Leogang, last year. The men's final was settled by 0.059 s, Goldstone over Loïc Bruni, the closest margin of the weekend. Take that gap as the unit: one Bruni. Hemstreet won the women's final by 0.865 s over Newkirk, which is 14.7 Brunis laid end to end. Same finish line, the distance between first and second measured in the smallest gap the weekend produced.

For Once, the Fastest Rider Didn't Win

6 min read

For the first time this season, the order on paper and the order on the day came apart. The winner was fifth-fastest across the weekend, the two quickest men finished third and twenty-third, and one rider has now delivered her perfect run at both rounds.

Nothing Left: Flipping the Podium

Shaw won by a tenth. But take each man's fastest version of every sector across the weekend and the podium turns over. Williams, third on the day, had a 3:27.039 in him, six tenths under the winning time, scattered across four separate descents and never ridden in one piece. Shaw stays first on this measure too, only because he has nowhere to improve: his perfect lap was the one he raced. He won with nothing left.

Comeback Canadians

Hemstreet was 3 seconds down at split one and won by 3. Goldstone was 1.5 down and won by 1.5. Same race shape, different scale. Each panel uses its own rider's seconds — slide them together to see the mirror.

Fast vs Fastest

Two World Cup finishes from 2025. Loudenvielle's top three crossed in 2.971 s. Leogang's top fifteen, in 3.040 s. Same finish line, same three seconds — five times the field.

The Traction Budget

7 min read

Every input on a downhill bike draws from the same finite pot of grip. Amaury Pierron had the World Cup opener won with a corner to go. This is where it went. The physics of traction, told through the 3.2 s swing at Mona Yongpyong.

Changing of the guard? Advantage Ostgaard

Höll set the pace for nine splits and led by as much as 1.45 s at sector 8. Ostgaard, racing as a junior, took the lead at sector 12 and held it to the line. The line below is Höll's running gap to Ostgaard.
