My hubby got a 'GB' place via Help the Aged (he figured it was an investment for the future!!) seriously, he felt it was a good cause having a dad of 92 he realised there were some elderly people who have no-one to look after them...ANYWAY they wanted £1400 minimum (and you had to say why you wanted to support them - applied on-line via their web-site) and to be honest, apart from people who knew my husband and his father it was quite hard to "convince" people that Help the Aged was a good charity, they seem to prefer to donate to 'my' charity (a hospice where my mother was cared for) all be it I had a ballot place and didn't need the 'support' so much. Consequently he had to 'donate' the remainder himself which was rather a large amount. (I had to withdraw just six weeks before and only 2 people still gave me the sponsorship!!) Also as another note, if you are weighing up about the 'conscience' thing and doing it for a charity you belive in, bear in mind this: the hospice I was 'running' for rang me at 9.00am the day after the marathon to "see how I'd done, as they couldn't see my finish time on the FLM results", after I told them I had to withdraw they just asked me if I was to run 2007 would I raise money for them then...it felt very much like a total business transaction and nothing like the feeling I thought it would be had I run and collected some money for them... just a thought thats all...
