Nick,
Further info on the Hillingdon intro to racing can be found at http://www.londoncyclesport.com/news_2005/sl_05_ld.html
Expect to pay £10 for most Surrey League races entered in advance via Paul Tunnell. Entry on the line (EOL) can be £15 provided spaces still remain.
Rob, see you at the Jaunts, IOW and Box Hill
