I set off from home at 7 am intending to do the short route. When I got to Kirkintilloch the heavens opened and I quickly found myself completely drenched. As I approached Lennoxtown I could see the Crow road completely covered in the low clouds. It was at this point I decided to DNS the sportive. These are roads I can do any day of the year - today they would have been utterly miserable.
I still had rule #9 to consider, though, so I could not just turn around and head home. I went west initially intending a short loop home. In the end, however, the weather slowly improved and I added a number of extra bits to my loop, ending with a respectable 95 km. Very good pace too, which was nice.
If the weather is nicer next weekend, I hope to be able to do the loop around Loch Katrine, to make up for the failure today.
