The evening time trials are open to anyone who is a member of a CTT affiliated club. They are probably the easiest way to start racing or can just be used as a good training session.
They encompass a very varied range of abilities so week to week you'll always have someone of a similar level to compete against, plus two Trophies are awarded for them at the end of the season.
If you want to have a go you just need to turn up at the clubroom to sign on. The entry fee is £2.50.
For details of how the trophies are awarded and of when the events are on see the Club Evening TTs page. If you are not a member of a club you can join the DMRC by filling in the membership form and bringing it along on the night.
