Ironman Lake Placid race wheels revisited, plus tires

I have Zipp 303s and HED3 wheels and a disk. I’m strongly leaning to the Zipps for that course.

This will be my first time at LP so I’d be interested in hearing other’s views of the proper wheel choice. I’m not good on hills…

I’m going to use Vittoria CX tubulars I think. Any comments?
