I think you should try some long MTB routes rather than “gravel”, you will find them much more stimulating, even if you can’t go quite as far in a day.
I was talking about routes that start and come back to London.
I am thinking about a MTB, although it doesn't make much sense unless you travel to places specifically for that, at which point I may as well travel to places for gravel riding. There is a lot of crossover anyway.
Likewise, just about everything I ride is out and back from my flat or less than an hour on the train.
There is a bit of crossover, but it’s all more fun on a mtb. As the fastest person on this forum once said, “gravel is all a marketing illusion”.
