... but there aren't usually crowds of people to help me off my bike at the top.
You say help but I see many of them as clueless idiots, interested only in getting their fat arses and faces on TV, regardless of whether that may necessitate blocking the progress of a rider.
I apologise for my outburst but, if you find yourself running sideways up a climb, shouting in the ear of a top pro, bumping into other spectators as you run, then you are a clueless idiot. I doubt that applies to anyone on this forum as we are all cyclists.
If I were a top pro I would, at the expense of the added weight and time, carry my big Zefal HPX
riot baton pump and beat some of those morons into a mushy pulp with it. (Why don't the official vehicles have Bodicea wheel spikes?)
