Oh so now it's how far you can go without stopping? Don't know, but my morning rides I do a little over 10 miles without stopping (except for traffic, if needed). But on my longer rides, I usually stop and take a short break after about 10 miles. I honestly don't know how far I can go without stopping, but a few weekends back I did a group ride where we rode 15 miles without a rest break. Or, I would have but a flat tire at about mile 14 caused an unscheduled rest break. I'm sure I've done longer on an organized century ride, as one of the stretches between SAG stops was probably close to 20 miles. But then I still don't know how many pushups would help me ride that far...
