I read several places that your cadence should be around 80-90 pedals per minute. I checked my cadence today and found I was usually somewhere between 55 and 60. I feel fairly comfortable at 65-70 on flat roads, but there are few of those where I ride and my usual 25 mile ride is all up and down, although it always seems there is more up than down. I am 65 and just started riding again about 4 months ago after a 30 year period in which I almost never rode. Should I try for a higher cadence or just enjoy my ride. I guess I'll get stronger as I ride, but should I really try to push it now?
