Thanks, @OzKnitter, for passing on this story from Cyclingnews: Dodging Cows And Pacing Yourself. The full story is at the link, but below is the vache-news. It looks as though one of the cows did a bit of a Hoogerland.
As the gun went off at 9:00 am, we stood there for another 30 seconds, waiting before we could start rolling on our bikes. From here, it was go time, Kris [Sneddon], Spencer [Paxson] and I made like a bunch of angry hornets and started hammering up the sidewalks, weaving around hundreds of cyclists and eventually up to the head of the race in 10 minutes time.
Lucky for us, the start was on a wide road and was relatively slow. I looked at Kris and gave him the thumbs up as it looked like we had dodged a bullet. Nope, we got content again and drifted back into about 40th position and then the road turned into a gravel path which was still ok, until three cows got spooked and hopped in the middle of the road, blocking everyone out of the top 30. Spencer made a bold move and rode up the ditch. At the same time, one of the fat cows also moved to the ditch, pushing my teammate into a barb wired fence. With one hand on the cow’s ass, and the other one on his handlebar, Spencer pushed the cow out of his way and snuck by. I was cracking up, but also getting pissed at the cows as they weren’t getting out of the way.
I remember hearing about Steve Gaffney from Calgary getting kicked in the face one year by a cow he tried to pass on the Bow 80 course and wanted to avoid the same fate. Eventually the cows cooperated and we rode by them, only to have a panicked cow 100ft up the road try to jump out of his pasture. Being a fat cow, he instead went through the fence and hauled all kinds of wire into the middle of the road. All the Euros started yelling “Ashtung”.
