I do not have a bike computer yet saving for a garmin. I have landmarks on the route I know the mile and i see how good I do when I get back. Only needed one bathroom stop 4:45 was the complete ride start to finish. The roads here are as flat as it gets along the gulf coast. I think I can get it below 4 in the next year. I really wish we had some climbs here. But we have no snow to worry about only lots of wind on most days.
