Lap one: find an effort you can repeat
The single biggest mistake on a two-loop course this steep is treating the first lap like the only lap. Whiteface climbs sustained and technical terrain on the actual Olympic alpine venue, and it is tempting to go out on legs that feel fresh. Do not. Whatever pace you hold on lap one, you owe your legs an identical effort on lap two, and a hard first climb shows up as a much slower second one.
There is a real intermediate cutoff here: you need to finish lap one within 2 hours 45 minutes or you do not go back out. Know your split target before you start, not after you are already behind it.
