Hi,
Went to my first trial 3 weeks ago and had the time of my life. I only bought the bike 2 weeks before the trial and had never been on a bike before so was absolutly shi**ing bricks about the trial. Everyone was really helpful though and gave me loads of advice. I gave up counting the number of times people said "youre new to this arnt you!!!!"
There was nothing that i couldnt have a go at and suprised myself on a few sections at what i could do, so dont worry about anything out of your depth. If there is something that you feel you cant do just tell the observer youll take a five and move on to the next section.
I went to the next trial i could as i enjoyed it so much but managed to break my front break lever off on the 3rd section of the day and was out for the competition. Really annoyed me as if i had a spare with me i could have changed it in 2 minutes and carryed on. I have just bought a set of spare levers for the bike so it wont happen again...i hope!!!!!! Might me good for you to do the same just incase!!!!!
Good luck anyway and i hope it all goes well.
