Yesterday's weather forecast has been updated. The BBC now think:
Any marathon runner would take rain over shine ... once they get going. The downsides of rain are threefold:
1) A miserable wait at the start getting wet and cold
2) Fewer people on the course cheering you on
3) Slippery man hole covers and rains
But give me a day like this any time over 20+C ... But as I write this the skies are clearing and I wonder whether the forecast is wrong yet again and it will warm up, making for a tough run for those finishing in more than 4 hours.
Good luck to all those running.
