Bike maintenance

On Saturday I am competing in the Ballbuster. This is a pretty tough duathlon which involves a 16 mile run and 24 mile cycle, up and down Boxhill in Surrey.

I've done it a couple of times before and it has become a good marker for me, for if I'm fit enough to complete it in a decent time I consider myself 'marathon fit' for the season.

As I've not been on the bike since September, I think Saturday might be tougher than previous years.
