I did a solo metric century (100 km, or 63 miles) today. I am very pleased with how my cycling fitness has progressed. In May, I rode in an organized metric century and was wiped out by the end. Today, I was only mildly tired. I could have ridden quite a bit further.

I have signed up for a true century ride in September, so I am increasing the length of my long Sunday ride every week. If today's ride is any indication, I think I should be prepared for a century.
