Looks like I am going to have to miss this one.
Most of the bruising on my hand from last weeks fall has gone but it is still there on the part that contacts the bar. Also I tried to take it round the block today (crappy weather for it) and the vibration through the bar into my hand stopped me after a couple of hundred metres. It didn't seem that bad at the time.
I've loosened the clip on the pedal, so hopefully it will disengage easier now and I wont have such a stupid fall next time.
