Thank you, shootingstar! I have a few "circuits" which I cycle, the longest one is 48 k, or 110 k if I go around both lakes. Yesterday I did the 48 k one for the first time after loosing weight, and even though my average was pretty much the same, I felt much stronger AND most of all, I did much better on the hills, where normally I almost fall off the bike from lack of breath! So things definitely feel better in that sense! I think I need to focus on all the positives
