I did the Man of Kent 200km Audax yesterday as mentioned by Ian. It was touch and go, as when I woke up to the snow was settling on the ground. However, this was my last chance to do my 100 this month and I am also trying to do an Audax RRTY (200km a month). I drove out to the start anyway and the roads were slightly damp but not icy and like the other 31 starters I decided to give it a go.
Headwinds for the first 50 miles to Sandwich were brutal, particularly when you were directly exposed to them. Worst time was when I got a puncture and had to fix it with the full force of the wind on my back. Ian, you will be glad to know that I am completely converted to CO2 inflation now. I was shivering badly when I got back on the bike. The next 70 miles were much better with the wind mainly on the shoulder or to the size. It was so cold my water bottles froze, but I am really glad I made the effort, as I am sure this will be the toughest 200km I have to do this year (famous last words)
