IT IS DONE! Thank you everyone so very, very much for you support. I'll post more photos (or a link) here in a few days. Also note that I can still accept donations for another couple of weeks, so by all means, if you'd like to donate to this fine charity, please do. The support the team organizers lent was well appreciated.
Thank you indeed for your support so far! April 17th is just days away! Once I raise £1500 I'll submit your donations for Google charitable matching. My generous employer matches 1:1 which means that the overall goal is well in sight! And, if your're curious, my runner number is 38027 and here is my running/London blog.
