Attempted my first metric century...made it 66 miles. The wind was low and the ride was good until I had a sidewall cut on my darn near brand new Conti 4000s tire. Noticed the damage at mile 24 or so. Limped 10 miles to a friends house and patched it up with duct tape. Ride saved. Tire? Not so much. Although the duct tape held well...I may land up replacing it anyway...
