F1 cars round Silverstone are being replaced for one weekend, by a few thousand bats people.

Among the throngs will be yours truly: yep, I’m entering the Silverstone Half Marathon.

Inconvenient, this, in so many ways – such as, for example, the fact I will probably fall apart by the end of it. Chief inconvenience, though, is the start time of the race. 12 noon.

Yes! Not only is it on the same day as the 1st F1 race of 2010, it is on at the same time. Groan. My only vain hope is that the good men of the BRDC pipe out the race through the race commentator speakers.

Here’s something, though: thanks to McLaren’s brilliant race dashboard, F1 has gone all ubertech for 2010. It’s now possible to track JB and Lewis in Real Time – see where they are, how fast they’re going, all sorts of stuff. This got me thinking…

… who fancies tracking my pained progress tomorrow? If you’ve got the computer up for the F1, maybe you could also pop open a window to check I don’t keel over en route?

Via the magic of Runkeeper, you’ll (hopefully) be able to do this.

I’ll be strapping the iPhone to my arm and, as the lights go out bloke with an air horn honks, I’ll press ‘go’. For, my lo-fi version of the McLaren F1 dashboard, on foot!

May work, may not… just in case, I’ll be posting updates on my blog while I’m not in action, checking on via Foursquare and Tweeting on the canny #f1silverstonerun.

About a billion people entered this last year, so I am in a small way looking forward to it. Mostly though, I’m dreading it. Share in my pain tomorrow, if you fancy a giggle…

I’m not the only one running – and so far, DealDrivers’ John has raised £750!
