I'm looking at a CWT hike in the Spring of next year, not least to give the TGO people something concrete for a 2021 Challenge with them. I'm not a fast walker either, averaging 4km/h on the Cowal Way, but happy to keep trudging on. I thought about doing it in reverse, Wrath to William. Going south the sun will be on the face, and arriving in Fort William knackered and dirty and tired there's no mucking around trying to get home. Depending on conditions (weather, me) could even give Nevis a shot.
If that sounds good feel free to give me a message or reply. I don't do the FB thing and am not about to start, I don't trust that Zoidberg thing that runs it.
