Would really recommend going and riding in the Alice lake area of Squamish for D3, check out Rupert, and you can break up the ride by swimming in Alice or Edith lake.
can you suggest a good lap for alice lake so we can program into our garmin?? stay around 30km and 1200 meters climbing( i think i did that math right, 20miles and 4k ft), or were going to be shit kicked if we try to push more than that.
SORRY This isnt whistler trails in whistler :P
