Sounds **** awful!
Nah, it was quite fun in its way. You do different rides for different reasons. I’ve done loads of scenic, technical, fun rides over my time. This was just a different style of ride. I was intrigued whether it was possible to do in a day, so tried it out. I wasn’t working at the time so it wasn’t like I was losing a big chunk of me time. And also I was fairly fit so I was recovered fine for the weekend to ride with the family.
Also, I had to take the kids to school in the morning, then pick them up at 15:30, cycle home with them and get them fed and sorted for bed. There’s only a limited range of fun/ challenging things you can do in the Cheshire plains in a day with those constraints.
Not like I could have done LoTL, or the WHW with those domestic commitments
Couple of weeks later I did Torridon Classic, Glen Sligachan, Cairngorm & Macdui and the full Cuillin Ridge traverse in one 4 day trip. but that required 3 additional nights away from Manchester, which is a rare occasion. So I just made the best of each chunk of free time.
If the OP had asked about the best, funniest, semi challenging ton then I’d have Defo said the WHW , but they didn’t. They asked about doing the first one from a position of doubt and inexperienced. In which case making things as easy as possible to achieve the stated goal is a valid approach IMHO
