Ric, if someone looking like that was behind me, I would put a Bloody shift on!! You look like a mixture of a criminal and Arnie!!
Went out for a run at lunch, vaguely thinking i'd do the 5x1/2miles at 10k. Got a mile in, the Ipod died, i could feel the hip a bit, and i had load of work on, with the boss in. So made sense to postpone! One of the few times in 2 1/2 years I've ever changed session mid way.
Quite fancied the track anyway, so went up there, and switched to 800s instead of 1/2m, with a resolve that I was going to thrash some 10k pace however things felt.
Came out alright, 2.36, 2.45, 2.44, 2.48,2.49
For a light session, was comfortably hard.
Had to make sure I wasn't going to run into a posse of casuals, with the hooded tops, gloves, scarfs etc, running the wrong way round the track. And also there were 3 bits of ice on each lap!! Therefore, the lap was 95% runnning, and 5% little jumps 
Pleased with it, freezing cold, dodgy conditions, first time back on the track for ages, made me feel alive frankly, quite bliss!
I'll give sunday a go either way now. If race day magic fails me, and a DNF or DNS occurs so be it, but should be ok.
