Winter JOGLE attempts get so much negative coverage on this and other mesage boards I just wanted to add some balance to that view point. I'm 45yrs and reasonably fit although not a frequent cyclist (running and football being my thing) but I just completed JO'G to LE (950 miles), solo and unsupported, in 10.5 days starting 5th Jan 2013.
I had a great ride and finished a day earlier than I hap (very loosely) planned. Of course it was extremely cold but i only had 3 wet days and my desired weather system of a high over Scotland (bringing cold winds but from generally dry and from the north) sort of happened. Physically I coped well, the biggest problem being numb hands (from thw cold and gripping) and weeping eyes from the cold wind. I had no accomodation booked which really helped to optimise each days ride as I had no constraints when to stop (obviously I targetted places where there would be a choice as some places shut up for winter). I had to start early so as to keep the night riding to a maximum of an hour in the evening, this meant short stops only during the day but a massive dinner and breakfast meant i was rarely hungry.
Anyhow I just wanted to put the other side that you can a very safe, rewarding and enjoyable JOGLE ride in winter with a little planning and preparation
