All very fair points - perhaps there should have been a disclaimer saying this list wasn't intended to be exhaustive! Essentially the aim of this article is to get people thinking outside the box and draw their attention to the wealth of possibilities for challenge walks that aren't the Three Peaks. A recurring wish of people who have to deal with cleans ups, rescues, visitor pressure etc caused by Three Peaks Challengers is that people would just consider other possibilities and spread the burden more widely. See this article for more background: https://www.thebmc.co.uk/the-three-peaks-challenge--what-do-you-think In writing this article I was thinking of the sort of people who would consider doing the Three Peaks, and trying to think of alternatives that would grab people for the same sort of reasons. The Pennine Way, Coast to Coast, Cuillin Ridge etc are all 'challenges' in their own right, of course, but they are a different sort of thing; you wouldn't contemplate doing the Cuillin as an alternative to the Three Peaks, nor could you do the Pennine Way in a weekend. I tried to explain this a bit in the intro and the final 'walk' but perhaps it should have been clearer.
