Bristol is believed to be the first city in the world to solve the 300 year old Konigsberg Bridge Problem, determining whether it is possible to cross every bridge in a city only once, starting and finishing at the same spot. Bristol has 45 bridges (although 2 are currently closed).

Variation: en direction ouest. Départ au pied du Mont Nicol-Albert au camping du Petit-Sault. Arrivée au poste John.

While less well known, there is a Presidential Range in the Green Mountains and this run seeks to visit all of them! Route probably should have a summit-to-summit variation as well, but given that Mount Wilson is fairly remote it feel like the route should be a complete circuit. Vermont, and its Green Mountains, are a truly beautiful area so hoping to add a twist on a classic White Mountain route to get some people out into the older New England mountains!
