I think I'm about Mel's speed. But it took me a while to learn how to read my bike computer (actually a trekking computer). It computes the other way 'round. I was really puzzled that I was going slower the harder I pedalled, then I realized it was giving me minutes per mile, not miles per hour. Woops. Don't tell my engineer DH or engineering student son.

So, yeah, last ride I was doing around 5-6, which means 12-10. On a downhill or spurting on a flat I could do better, even down to 3 , but then I bailed out on hills and walked , so I guess my average is around the 10-12 I was doing on flats. Which means the Cindy will take me at least 6 hours. But ... I think I can maybe keep going that long at that speed. I've never had or loved speed, but usually done better at endurance. 'Course, I only know my endurance from hiking and lap swimming, but I'm counting on it holding up on a bike as well.
