Prep for ultra long
Terrain will be tricky technically in places for sure. Especially as is quite flat similar shapes and fast moving so bearing accuracy will help a lot in keeping on line.
Crags on training map don’t seem very obvious.
Using a ping pong approach seems to work best especially near control. Needed to be accurate for which feature are looking for. So keeping a small bubble of knowledge around the runners location.
Instead of looking for high points all the time try looking for contour shapes that are obvious when crossed. Th is approach seems to work much better as it allows one to stay on a direct line without drifting so much.
