The Welsh 3000s: Nant Gwynant to Rowen

I started looking at the route for the Vegan Welsh 3000s for 15 June.  If the weather stays OK and we do the full route, this table shows the ascent and descent.

These tables are based on the spot heights of the peaks and lowest points in between, from the OS 1:25000 maps. While this is an approximation, and ignores any undulations, it should be reasonably accurate.  Most of the paths are either "straight up" or "straight down".  That's a leg wobbling warm up of an ascent up Snowdon!
