Ride what ya like, like what ya ride.

I did 200k+ (131 mi) on my df yesterday. No df-specific aches and pains today, but I have spent the last 50 years getting my fit dialed.

I've also done some (ridiculously) mega distances on 'bents - up to 1200k in < 80 hours, with no untoward discomfort.

Lesson? Both can be kind to the body, but the df may take more effort to get a proper fit.

(FWIW, I celebrated the big six-one earlier this year, so age isn't necessarily a determining factor)
