We had to go back to the bike shop on Friday to pick up my old bike from a tune up visit so we decided to go on a tour of some parks about 10 miles from the shop. The paths in these parks are much based on the terrain so we had lots of big hills to traverse which was new for Cheryl. So we had to review and practice gear shifting on her bike so that we could move through the park, by the end of the ride I think she was doing pretty decent and we will have to try again so that maybe she can try some of the country roads around here with me on one of my local rides.
