For people who are not familiar with the ridges, here is the "Ridge Map", a tool which has a lot of the landmarks, mountain names, routes and useful information listed:

For Jonathan's flight, I created a new Layer on the very top called: "Jonathan's 1000km Task". I eyeballed the turnpoints, so don't panic if his track doesn't quite touch them tomorrow.

The main layer is called "The Ridge" which has the most relevant information.

All the best,
Daniel
