Dog Sledding and Biking in Madison?

This video is from the Wisconsin Bike Fed Blog.  A guy named dude was biking to work after a recent snowfall and passed up a woman getting pulled in the streets of Madison with two sled dogs.  I can't believe the dogs couldn't beat the biker.  If you like dogs and biking, check out the cycledog repurposed bike tube collar modeled by my dog below.  She doesn't let anyone pass her in the snow.
