I couldn't live in a city where I couldn't bike at least 20mph through the whole route. I'd feel as if I was standing still.

Do you live in a very flat area?

When I was a teenager, I was state road champion in my age group and nationally ranked. I was very light and hill climbing and bike handling were my biggest strengths when competing with category 1 and 2 riders who were older and fatter than I was... I rode over 10,000 miles a year at that time. Glory days...

My route is amazingly flat.

I either rise by 15 metres or drop by 15 metres, over 9.6 km.
