Bike set up

I was wondering if anybody had any advice or ideas about setting up my bike for triathlon.

I have been slowly getting back into my riding and have purchased a set of tri bars to get used to using. However I am sure that my riding position isnt really correct. Ive tampered and played around with it for ages but cant seem to get it 'right'.

Does the club do any bike fitting evenings/get togethers? If so I would love to come along and get mine properly set up before I start serious training.

Many thanks for any help and advice.
