So I will do it again in one higher gear, etc. I am also, on the advice of my trainer, taking a long steady climb on the morning ride in the highest gear I can manage. So far working well -shaved 10 minutes off my commute time.
If your legs are strong enough to handle it, take hills in a middle gear in the rear and smallest gear in your front chainring. You'll be at a lower RPM but you will ride the hill at a faster pace. I'd rather exert a little more effort for a shorter amount of time than struggle up a hill at a really slow pace with light pedal pressure.
