I'm 66-1/2+ and recently increased my distance to hit 2,500+ mi/yr. on my mtb. Next summer I'm planning to start backpacking again (8-10 mi. trip ups to 10,000+ ft. elev. after not having backpacked for 10+ years).
You're only as old as you feel. And you only feel/get old if you stop doing things to keep your body (and mind) limber and conditioned.
Keep doing what you're doing (riding and any other exercises/activities you may do) so I'm not out here all by myself
