Yeah...well trust me 4 degrees is not normal for us....but it's supposed be even colder by the end of the week....

With standing I can see now that I'll get better over time if I stick with it. It's actually easier for me if I have a hard gear and keep my cadence low. I rock the bike and lean back a little to make sure I'm centered over the crank....like you I got about a couple 20-30 second intervals this morning. I think once I get my standing position locked in I'll be able to bring my cadence up

Keep rolling...
