Ratzer, the atmosphere is fantastic and you will find what you need to cross that finish line. Promise!
Cheers, KK. I should mention that run was 21+ miles, so only 5 to find. It's just going to be trying to fit them into the same time that might be more difficult!!
D'ya know what, I've never even spectated the LM in any incarnation. I think while I was studenting in London, once upon a time, it always fell in the Easter break, otherwise known as the revise-bloody-hard-there-are-exams-in-May break. I am looking forward to a great day out, punctuated by gritting teeth and aching feet - but that's what a day out in London with the kids is usually like!
