- Y. O.
Dude... Why are you beating yourself up?Oh my, It may be time to consider packing it in. Woe is me.
First and foremost measure your bike rides by enjoyment, not distance traveled. I measure mine by time spent in the sun.
If you need to take breaks during a ride, do so. Bring a piece of fruit and some chocolate covered espresso beans and make it something you look forward to.
Realize all these measurements are geared towards the young. Not that they aren't useful but they don't take into account an aging more delicate body so you'll still have to final fit to your bodies limitations.
I do agree with the comment above... a saddle too high is far worse than too low and puts more stress on your knees by over extending... especially damaging as we age.
Your search for the utopian solution is robbing you of the reason we ride... well at least why I ride.
Enjoy.. it's awesome weather here in the NE this week.
