I've raised £150 to help raise money for epilepsy action

I have been thinking about raising money for a good cause for months and not sure which one so I've picked to run the BIG HALF marathon in London in march for epilepsy action as a challenge for my self and for a good cause.
the reason why done this is because my best mate little boy has a condition called ohtahara syndrome which is bad epilepsy that get diagnosed to babys before they turn to 3 months old and as there is no charty that run for it in marathons epilepsy is the closes thing to it
if would love to sponsor me I would be really grateful for it and its my first ever marathon (which I'm going to be shitting it lol) and for a challenge for my self,for my best mate and a special little bot that means the world to me who has been in and out of hospital through the year and has to change medication is worth every penny I will be raising and I might get better medication for him and other babys and around the UK.
thank you
