Wow Longers that sound like a tough one.
Cat and fiddle is on my must do this year.
As for myself 74.6 miles on a 60 mile RT, afew weeks back.
We got horribly lost, I was absolutly shagged at the end of it.
92miles - freezing, intensly hilly, very greasy and ridiculour headwind. One of those rides where you get home and ask yourself why the hell you just put yourself through that Plus I made the error fatale of giving away my last go-gel to a lad who was bonking, who drank it then gave up and called his mrs to rescue him. I duly blew up and grovelled a good 20km, every tiny incline putting me in 30/23.
