I had just shy of 50,000 very comfortable kilometres on this saddle before the bicycle and saddle were stolen at Easter in 2010. Those kilometres included one 1000K randonnee and two 1200K randonnees, and a whole bunch of 600K, 400Ks, 300Ks, 200Ks, centuries, and shorter rides ...
Happily, we recovered the bicycle 3 years later, but unfortunately the saddle had been sold, and the buyer was not willing to part with it.
Since 2010, I've divided my time between several Brooks saddles, but have been comfortable on all.
