Training road bike ride 40-50 miles

I will be doing a training ride to get time on the bike seat. It will be about 50 miles on secondary roads mostly in the Dover area. The pace will be about 13 mph. There will not be many stops. The course wil be determined as we go with the hope to get some good hills in. Email me if you wil be joining. If I don't hear from anyone I might leave earlier or later depending on when I wake up.
