I'm running the London Marathon (fiddly) on 26th April. So I have to do training and probably wear a headband. So you should give some money to Shelter so they can divert people into houses so it all feels more worthwhile.
My training is going well. Today I ran about a hundred miles which is tons more than a marathon so I can't see it being a problem. I've got swish trainers and shorts too so I'm feeling confident.
If you give money on this page it's secure (peace of mind) and if you're a UK taxpayer (I know some of you are) then Justgiving adds 28% to your donation.
I suggest you just donate all you have (or can give).
Thanks.
Tim.
