Hello all. I've been lurking a bit (somehow can't stay away....). Yes, I'll be stalking on the day, up at 4:30am, wearing my hat . Sorry to hear about your hip Debra, that really sucks. Congratulations on the book prize though - well deserved!
A word about insurance policies - check with your insurance company whether you're covered for Comrades. Some will include marathons in their policy, (but it's still worth checking even that - I had a very protracted conversation once about what 'marathon running but not racing' meant). However, very few policies will cover races of over 'normal' marathon distance, like Comrades, as standard. You might either have to pay extra, or go to a specialist insurer, like Dogtag, which does extreme sports cover. Always worth checking, you don't want to find out the hard way that your policy isn't valid.
Smudgerncfc - no, the routes are different. The May one is what used to be the BUPA 10k which starts and finishes in St James's Park. The July one appears to be what used to be known as the British 10k, which I think also finishes in that area but starts somewhere in Picadilly. Not sure where they go in between. In previous years the BUPA one has been significantly better organised, especially if you're going for a time.
OnTheBeach - depends on where you're coming from, but definitely possible to get back to many places in the UK on Sunday night or even at a pinch Monday morning. I got the 7am Eurostar this year and was at work in London by 9:30am, and there are early flights too. Because of the time difference you get an extra hour of travelling time.
PatrickNSF - I can't remember when the entries closed last year, but I think you'd be OK to wait until you hear about Boston. I have a feeling it was maybe November? They do start to say on the website when the number of places is getting low. The longer you wait, though, the more expensive it gets.
