To be fair, @vorsprung , they had both done a 200+ for October by successfully completing their 400 2 weeks ago, on (Met Office authority) the "wettest day [in the UK] on record, with enough rain falling to more than fill Loch Ness, said the Met Office [whose] data shows Saturday 3 October 2020 was the wettest day" since records began (1891).
And KSW600 is scenic, even in the summer with 15 hours of daylight.
