I rode in this morning on my new 700x42 Ritchie ZED cyclocross tires. I'm converting the bike over for an upcoming 4 day ride of the C&O Canal and wanted a test run. It was fairly slow going but the big tires soaked up all the bumps that I usually feel. I got used to the constant whirring noise that knobbies make on pavement and enjoyed the cooler morning temps (although it was somewhat humid). Once I felt comfortable on the new, heavier tires, I picked up my speed a bit and took turns leading and drafting with another rider until I dropped him on an uphill sprint near Independace Ave. I'm leaving for Cumberland Thursday afternoon but will likely continue to ride out the week, just at a much easier pace.
