I have finally managed to allocate all but one of the prizes. It has taken a lot longer than i anticipated due to holiday, illness & injury etc. Might have to think the details of this through better if i do it again!
Sadly on looking back at the form i have no way of contacting 'sarah' who sponsored me at the farmers market.
So after a redraw with random.org i have the final prize to offer to Gywn, a friend at the gym.
