Before entering an event, ensure that your bike is mechanically sound (brakes work, no loose spokes, bearing sound and most importantly, a working engine stop switch) and you have all the proper riding gear.
Turn up at the venue in good time to allow plenty of time for signing on, checking your bike and getting into your riding gear. While most club events don't operate a time limit, if you arrive and start late you might find that sections have been closed by the time you get to them towards the end of the trial. Nobody wants to hang around (perhaps in foul weather) waiting for riders who didn't allow sufficient time to complete all their necessary pre-start tasks.
The start of the event is usually indicated by a long blast on a car horn or an announcement from an official with a bullhorn. When you hear this, proceed to the start area on the road by the site office and wait to be told to proceed onto the course by the starting official. While waiting, you may be asked to sign a starting sheet.
The first section is usually close to the starting area (consult the course map displayed outside the office before starting) and you can just follow other bikes. If not, follow the course markers as described on the rules page.
