I have not climbed this one for a while. It involves 2000m of total ascent, so an early start and fast pace is required, as we need to do this in daylight. I will check Whistler Peak webcams to see how much snow came since the weekend.
Headlamp is essential. Possibly microspikes. Poles for me for sure. Speed!
I have done it twice before, both times over 10 hours. 
I will be coming from Whislter and we can agree meeting place. If coming from Vancouver, the meeting time should be 5.30am (good luck)
