For those who looked out of their windows this morning, ready for perhaps the last long run before next Sunday's London Marathon, you have my sympathy.
Last year's run was a challenge for almost everyone because of an unexpected heatwave - I was hot just sitting in the stands watching the finish; I can't imagine what it would have been like running for a few hours in weather like we had this morning, had the marathon been today.
It's not like you're expecting to sign up for the North Pole run when you sign up for London.
The forecast for the end of the week and into next weekend looks much better though - sunny and perhaps 11-13C. Let's see if the forecast holds.
