This is definitely NOT a road race! There is about 1k on tarmac, but the rest of it is on (mostly good) tracks and fields. There are a couple of hills (including a long, steady climb at about 8.5k) and a short section that is likely to be pretty muddy. I would recommend trail shoes, although road shoes should be OK unless it really pours down between now and Sunday. Enjoy!
Don't get me wrong, I can be as obsessive as the next man (or 'far out hippy chick' for that matter): driving round the course the day before, poring over the route on Google Earth, checking out the predicted wind speed and direction, etc. etc.
However, when the race starts, I generally don't feel the need to wear something on my wrist that makes an irritating bleep every mile or km (yes I know that you can turn the sound off, but nobody else ever does, do they?) and tells me what pace I'm running the whole time. I know what pace I'm running: generally as fast as I can sustain for the race distance, thank you. If I can go faster, I will. If I have to slow down, so be it. My finish time will usually be the best that I can manage on that day, on that course and in those conditions. I'm certainly no 'elite athlete', but I've worked with a few who are (or were) and I've rarely seen any of them use a Garmin in a race (on some training runs, yes, but that's a different story altogether).
Sussex Runner: why not give it a try? no watch, no Garmin, no heart rate monitor - just you and the feeback that your mind and body are giving you all the time for free. Race this way and you might discover that your limits are not where you think they are...
Sorry Cheerful Dave, couldn't resist stirring up a bit more controversy!
But doesn't it make you laugh when you get people turning up to races carrying Garmins, iPods, mobile phones, etc.? A race should be you against the course and/ or the other competitors, not a display of technological one-upmanship.
And as for the tired rants along the lines of "this was supposed to be a 10k race: my Garmin measured 10.07k so the race director should be taken out and shot"... Not that this applies in this case, where the Race Organisers have clearly made a real mistake.
