Last year I finished in 9hrs 50, but took it easy and spent time taking pictures and phoning home with progress reports.
This year I'm a lot fitter and quicker, I have a coach and have been placing in local races. Last weekend I completed a 115 mile ride (with about 3000ft of climbing) in 7 hours.
This year I'll be riding to finish in hopefully around 8 hours. So no camera or phone calls. Of course that's assuming that it will be dry and warm.
I'm used to riding in temps of 90-95 degrees, so the afternoon riding was perfect last year, the morning I struggled as I found it too cold.
