The NENSA has a Standardized Ski Fitness Test.

I wonder what the records are for US skiers (and other athletes) and
if top skiers from different countries have taken the test.

Offhand, I'd think these numbers might be good precitors and that top
competitors might not want their stats to be broadcast. But ya never
know!
