7.0 mile trip
29.8 mph max speed
12.8 mph avg speed
This was just a basic hop to Florence and back. I took the back way there (Mullican Rd.), and back via Florence-Byram Rd.
Perhaps a good goal to set would be to make this same trip in under 30 minutes. Considering how much I had to slow down and divert myself due to traffic, better conditions may make that an easy enough achievement.
Since I don't blog every single bike ride, I can't say with certainty what my true average speeds are. However, I do record enough of them with details about routes, load, and conditions, that it may be possible to work up some fairly meaningful figures.
