Three days to go until the London Marathon, and all my preparation is done.  I'm now carbo-loading, which has to be the easiest part of the training.  Tomorrow, I'll go out and run about 4 miles to keep things ticking over.  It's funny that at the start of the year 4 miles was a run - now it's hardly worth getting my running gear on for!  I suppose that's a sign that the training has gone pretty well.

The one thing I have no control over is the weather.

Having trained in great conditions for running (nice and cool, maybe a drop of rain, little wind), the weather this week has made a turn for the worse/better.  It's pretty warm and humid at the moment, and not ideal conditions for long-distance running.  So I'm wondering what it's going to be like on Sunday.  I've consulted two different sites for their forecasts, and they are markedly different.

The Weather Channel v the BBC Weather (if you click on those links you'll see the forecast from whenever you click - so no point clicking on them sometime in May, unless you're interested in the weather forecast for London from then).

Anyway - this is what they say the weekend, and most importantly Sunday will be like:
