The Tour du Mont Blanc is a classic of the road bike long distances trips. This is a tour around the famous Mont Blanc starting in Chamonix via Col des Montets then Col de la Forclaz, Martigny, the Col du Grand St Bernard, Aosta, La Thuile, Col du Petit St Bernard, Bourg St Maurice, the Cormet Roselend, Beaufort, Col des Saisies, Megeve, St Gervais, Le Fayet and return to Chamonix. On the map, it seems nice and easy but in reality you should count 325km and 7400m of altitude gain.
We chose to do the trip in two days. That gave us two big days of 7hrs30mins. Starting early is important to avoid the heat. There are many fountains along the way to fill your water bottle.
