How do you find distances on routes/tracks?

Just open route properties. All information on the route is there.

As you seem new to BaseCamp from this and your other posts have a read of this, it's a good guide to using BaseCamp, although bear in mind it's written for nuvi and zumo owners so not all will apply to your Etrex.

Yes, new to BaseCamp and to Garmin. Thank you for the document. It looks very helpful.

I'm sure there's a simple way to query a route on BaseCamp to see how long it is in mi/km/whatever, but damned if I can find it. Little Help?

Open the route, select the route on the map with a click of the mouse, and at the bottom of the Basecamp window it will show total miles and estimate time.........also

Double click the route and a route window will open which will provide more detail including distance and time and GPS position for between every via point.

Good tip, I'd forgotten you could do that.

It seems this information is available on ROUTES only. TRACKS gives distance between points, but not total distance relative to a starting point.

Not sure which information you're referring to but if you highlight the points in track properties you get given the distance they cover, also if you use rkrus2 tip about clicking on the track on the map the total distance is shown at the bottom.
