I am listening and obeying the advice. A bit fed up as the running mojo has come back and the body is not up to it yet. Great that I can cycle and also keeping up the swimming, the turbo is set up and the old 2 in 1 cross trainer is sold and out of the way, so no excuses now for not practising the pedalling malarkey.
Mr steady gave his commuting bike a service and put a new chain on, I was in the garage at the time watching and he asked me to pass him the chain link tool 
no help at all, I didnot have a clue what it looked like so he had to get it himself, I can recognise different allen keys, spanners, screwdrivers, pliers but not a chain link tool. Need a few more lessons in bike maintenance at some point.
Anyway I have a HM race to go to on Sunday, but I am helping out only, think it will be a long morning as got to be there before 8am and finish about 1pm.
Good luck Mathschick for yor trail run and any others rushing around at the weekend.
