If successful some members of the team will then make a wingsuit descent of the route.
This expedition is being filmed by Alastair Lee of Posing Productions and has been christened, The Asgard Project.
Throughout the summer the team did a number of training exercises in Italy, Spain and the USA to get fit for Asgard and you can view three clips below.
You can keep up to date with their progress at: www.theasgardproject.com
The Asgard Project film premieres on Friday 20 November at the Kendal Mountain Festival.
Leo and the team are being supported by Berghaus and Nokia.
