I stupidly entered into a Strava cycling contest to cycle the height of Everest in May. That’s 8,848 metres of uphill although not in one cycle thankfully.
Here are a few highlights so far, including the Plaine Joux from Chamonix (Elevation gain 2,149 m. % Avg : 5.46%. % Max : 7.2%) and the Emosson Dam in Switzerland from Col Des Montets (Elevation gain 1,768 % Avg : 8.5%. % Max : few sections over 10%)
