I've raised £100 to raise funds for St Matthews Scout group

Hi all, I have decided to run the Brighton Marathon.
Bad idea, I know! but I can't pull out now. For the past 4 months I have been training in awful conditions, snow, ice and rain or incredibly bored staring at a wall on a treadmill for hours on end. I also add this is my first and probably my last marathon. Injury and illness and life in general has tested me to the limit. But I guess I am as ready as I will ever be.
For those of you who don't know I have been a cub leader for the last couple of years helping out at my local group RTW 19th St Matthews Scouts Group. I would love to be able to raise some money from this epic day of pain and suffering I am about to embark on to help towards activities for the children.
If you could spare anything to sponsor me it would be very much appreciated and all the proceeds would go to the group. It is kind of like walking o my front door in Tunbridge Wells and taking a jog up to Dartford. I am dreading it.
Thanks Ant
