If you're interested in the competitive side of cycling and want to know how to get involved then read on.
Firstly, there are two sorts of time trial events: Club events and Open events. Club events are open to anyone, even if you're not a member of a cycling club - because you can become a temporary member of Charlotteville for that evening. Generally, there is no need to enter in advance for club events, you can just turn up on the day to sign on and ride. Entry fees are currently £2 for Charlotteville CC members (first or second claim) and £3 for non-members. Courses and events are described in the 'Events' section of this website.
Then if you want to step up from there you need to look at Open events (which as they suggest are open to, and organised by, all clubs). When I say they are open to all, they are open to riders from all CTT affiliated clubs (except where there are restrictions such as needing to be a Veteran/Lady/Tandem/Trike etc.) Being a member of Charlotteville CC means that you can tick that particular box. Entry details for each race can be found in the CTT handbook which contains all open event listings. The races take place up and down the country on all weekends (and many weekdays) during the year. You have to enter the event about 2 weeks in advance using an official CTT form (which can be found here). Races are usually about £6-£8. Entries are based on previous times and for most races the field is selected on the fastest riders. On the day of the event you need to go to the race HQ and sign on (where you also get your number). You must either wear club kit or plain coloured kit. You are not allowed to wear either trade team kit (unless you happen to ride for that team) or kit with any advertising that is not an official sponsor of your club. Make sure you get to the start about 5mins before your start time and then its pretty much as you would expect for the rest of the race. Results are usually posted on a board in the HQ and in return for bringing back your number you usually get a free cup of tea. There is now also a section on the CTT website covering a 'Beginners Guide to Time Trialling' so go look at that too. Enjoy your ride!
There are two articles that are part of the Race Team section of this website that you should look at. Firstly a general Beginners Guide to Road Racing and then an article on Veterans Road Racing. The key thing is that, in general, you need to have British Cycling membership (and you can get discounted membership for the first year either through the club, contact the membership secretary, or just by doing a bit of 'Googling') and even a racing license to take part although there are exceptions these days (Go Ride events) where you can try out road racing without having either British Cycling membership or a license. Read the above articles for more details.
Not competitive events but they are very popular these days. You don't have to be a member of a cycling club to enter these events but its nice to ride with other club mates. To find lists of these rides go to either the British Cycling/Everyday Cycling website or the Cyclosport.org website. There is also the Guildford Cycle Challenge which is our very own sportive.
