Get a map, Whistler & Blackcomb are fuckin' huge.
Figure out where you want to go based on skill & terrain, use the map to get there.
I've been there maybe 20 times, so I know the mtns a little bit, but even now when I go I grab a map.
If you don't know where you want to go, you'll get funneled into boring runs that everyone else who has no idea where they are going are on. These runs are super boring, crowded & icy as fuck.
A sweet run for your last run of the day is the Dave Murry Downhill, it's a Giant slalom race course where you can go as fast as you can. There are no hairpins or other obstacles so you can tuck & bomb the whole thing start to finish.
I can pretty much guarantee it will be the fastest you've been to date on a board.
If whatever doesn't kill you, only makes you stronger.
Then I am so close to immortality
