Campsite is underwater so no M5 for me!!! May be able to make this but am requiring some honest answers here.
'Local knowledge' suggests a geared ride and out of the all the bikes i ride, the only ones with gears are a Pashley tricycle and a Raleigh Lenton Clubman
So honesty please...i'll have a go on the Lenton but how fast are you intending to average? I reckon i could average about 16 / 17 mph or maybe a touch more with the adrenalin flowing (sorry for the imperial) but i don't want to hold people back.
Let me know what you guys think....
