Just about to post a 55 miler in the challenge ,before I get called out for not completing a metric century . This ride is below my 10% of another point rule 😀. Good job I hadn't got to 55.8 because then I would have had to past home go downhill then back up just to get that extra point to prevent being trolled in my own thread 🤣
It is an interesting point...
I don't do many rides around 40 km now. I would usually make the effort and extend them to 50. If I can't be bothered to do that I often end up shortening the rides to say 25-35 km!
Similarly, for rides around 80 km. Any more than that and I would try to stretch to 100 km. A bit less and I would probably shorten a ride to 50-ish, saving my legs for another 50 or even a 100 later in the week.
I don't do many rides longer than 100 km these days. If I did, 130-plus km would probably gets stretched to 161 km (imperial century). Anything significantly over 161 would remind me that I used to ride quite a lot of 200s, and maybe it was time to do another one?
I suspect that I might never ride 300 km, especially because I would then feel obliged to actually ride 322 km to get a double imperial century in!
