So instead of walking the 105 miles I decided on using the mountain bike.
Using the huts meant the packs could be kept relatively light, everything I needed fit into my Osprey Escapist 25, including 2 litres of water.
The plan is to drive through the night. Between two of us the driving could be shared, making Chamonix for Monday morning.
A short ride is planned for Monday, taking the cable car at Le Tour and descending down to Trient where we have booked a hotel.
The only other hotel is booked in Courmayeur for Wednesday night, where we are sampling some of the famous Italian hospitality. This means we will be phoning the huts ahead for bed places, depending on the distance we travel.
If all goes to plan, we should be in Chamonix on Friday, leaving us a short ride back to Le Tour Saturday morning.
