Nice but not necessary: if the altitude does not need setting at each new place, and if it wakes up when you start and sleeps when you stop. Computer connection nice.
Thanks for any help. Have looked at threads but haven't found comparative coverage of current models.
What you're asking for is impossible without something like GPS. Hell, even with GPS, this goal is nearly unnobtainable but at least with GPS your data can be corrected later.
What you need is a Garmin Edge 500 and a Strava account.
