I know some people run a GPS that provides them with velocity information during a run. I am wondering if any of these units are capable of saving velocity data with respect to time. I don't really think that I'll have time to look down at small screen during a run, so I'd like to get something that I can plug into a laptop after a run to read a plot or chart of velocity vs. time.
I don't want to pay the money required for a data logging system, especially since at this point the only data I'm interested in is velocity.
Thanks for any help, Matt
