I've got to know because I am SO slow compared to dh...his is like 12.5 or 13 I'm just 7.8...I try to build up but with the kids sometimes it's a week between rides, sometimes I go every day of the week. Where do we all stand on speed and how long have you been mtb- ing? Dh is getting ready to go to a Navy school for 3 weeks and I might get one ride i n while the in laws visit over a weekend...sigh maybe it's time for a trainer
