Paul certainly knows how to succeed in the sports arena and is currently a member of the Guernsey FC Squad and has played football to a high level in the UK.

I am loving the triathlon training, In less than 3 months my 400m Swim time has really quickened up. Russ has helped my confidence massively and I continue to improve all the time.
