As spring progresses, I can tell my fitness is going up, since I can climb fairly short hills seated in a faster gear than I could a few months ago...and I can also climb longer out of the saddle than I could a few months ago...however, my first instinct upon starting to slow down on a hill is to stand up and pound away...The other extreme is to go granny gear and spin, going very slowly...I don't seem to have much in between.

Help me learn to go up longer hills at a strong steady pace!

All tips and advice welcome! Thanks!
