sprinting up Ruxton,,, or even on Manitou ave,,,, is a huge mistake you will pay for later,,, go out easy, your energy will be needed later. I have Matt's book,,, says the smart runners know the race doesn't begin till Barr Camp,,, and really smart runners, know it doesn't begin till after tree-line... or something like that. this is a cracy race and what you do int he beginning will kill your finish (finish could be your last 3-6 miles) race starts flat,,, so folks like to run,,, don't, it get real steep quick and you WILL walk!
