I'm sorry to hear about the injuries: I hope they get better soon.
marrows - Thanks for the list of celebrities running Virgin Money London Marathon. Not may are familiar to me, though I'd imagine most would benefit from P&D 18 weeks up to 55 miles! Will they be wearing something distinctive by which we be able to recognise them whilst they are running?
I completely agree with the comments about charities. I ran for a small local charity the first time I ran a marathon (Brighton 2011), though I didn't get my place from them. I don't think you can reasonably ask friends and family to sponsor you too often. Once every few years seems as much as I'm prepared to do it.
Lit - Thanks. That's very comforting. In which I'll deem last week's 20-mile target marathon pace run to take its place. Obviously I'm doomed, we're all doomed, as they used to say on "Round the Horne".
Macca - I don't think you're experience is that unusual. I quite often get delayed onset muscle soreness, am not that often tired the next day.
Lit - Thanks, and good luck at Reading, I gather it's huge. Of course no-one mentions it round here. Anyone else doing the TW half, it's a great race? I suspect there may be entries on the day, but don't take my word for it. Those looking for 1H50 will find yours truly as one of the pacers.
15W - Thanks. I'm worried about you saying you think 3 weeks out is too close for a half. I'm doing Paddock Wood 2 weeks out, and aiming to go quite hard, as I think I can improve my PB at a half, but I'll struggle to improve my marathon PB at VMLM. As ever there's a balance to be drawn.
And I still haven't done the 7-mile Lactate Threshold run!
