Hi Star Shaped
Welcome to RF and good for you for entering a race it definitely gives you motivation to get out there.
Most 1/2 marathons you can enter without having to go via a charity however, I am not sure about Leicester. I would try for a place first and if you get in on that basis you are not then bound to that charity on how much you have to raise for them as that can be quite a pressure on its own without the training you will need to do to prepare for the 1/2.
Good luck and keep us posted on your progress.
