Thank you all for the support!
It helps so much to hear the advice and experience of those doing it longer than me. Good to know that we all have our nemesis hills and I love the idea that "if I get up the hill and am still upright, it's a good day!" BleekerSt - sounds like we have the same athletic background (none) and it reassures me to hear about your progress!
This morning I rode solo for the first time (I always ride with my husband, who rides at 14-15 MPH). But he had a dentist appt this morning, and I wanted to ride, so I did 20 miles on my own. It felt awesome to just ride at my own pace, with no stress that he was "waiting up ahead for me." I wasn't trying to hustle, but ended up clocking 10.5 MPH.
More important than that it just felt good to be out there, just me and my bike. :cool:
