Cyprus, bottom of Happy Valley , sea level, off road to the top of Mount Troodos at 1952metres. 5.5 hours up, kebab and chips at the top, then 2 hours down….
i have ridden from Le Chable (821m) to col des Gentianes (2950m) when out in Verbier. Half the descent ie 1500 to 821 was done before the climb and the rest afterwards.
