Okay, I might be seriously nuts this time. Dublin was just a decoy 
So, I've emailed a swiss bike hire company but not got a response yet. They're probably too busy laughing.
It's 77km from Geneva to my spot in the Alps, the last 10km climbs 600m.
I've driven it many times, and the amount of traffic usually keeps the ice off the roads.
It would be about 2ºC leaving Geneva with scattered showers, later 3ºC with a bit of rain and snow, then down to 0ºC as I get up the last 600m into the mountains.
I'd need a road bike to cover that distance in reasonable time, but the climb at the end could be a nightmare. I'm sure I've seen cyclists on it before, but the drivers can be nutters.
Are there magic tires like winter tires for cars?
Am I mad and need to stop now, close the thread and think of my family?
