>>Of course there is some error since you are not traveling in a
straight line with the road curves.

positions of the satellites being monitored.
I've been using a cheap garmin plain jane (no maps) for my runs, as my
speedo is so-very-f'n-off (whatta what? Super Low rear gear and small
tires). The speedo function is good, but the ave. speed, max speed, run
time, idle time functions make it way cool.
