Anthony Hall’s race prep included replacing work jockey wheels. It turned out that one of them hadn’t been bolted on well. The ensuing story is a must-read

After throwing my bike down in rage I stood for a while cursing, then frantically searching walking up and down the track, staring at the puddling mud underneath the onslaught of hundreds of riders furiously speeding past, wild staring eyes, the jarring buzz of over 300 wheels repeatedly hitting the cattle grid nearby – into which potentially my jockey wheel had gone. I couldn’t find it.

Great blog Anthony.
