You missed the point.

You can draw your own lines in GE - no need to do the walk first -
then d/l them to your gps as your map. You just have to see enough of
the area you want to walk to be able to make out the roads/trails you
want to map. It is not too hard for roads and for hi-res areas, but
difficult for lo-res or no roads.

If you want elevations - as in topo maps - why not use ibycus? (I'm
sorry - did you already rule this out for some reason?)

If you ever want elevations, just get the 90 meter elevation data from
(? can't remember off-hand) and make your own. But of course you need
slightly sophisticated software to do this.

No, I think it was you who missed the point! As I said, I don't *know*
the actual 13 or 14 paths we will walk during this fortnight. I have a
brief brochure description for each, in areas I'm totally unfamiliar
with. Here's an example on day 3.

"Banff National Park: Ink Pots
------------------------------
Following Johnston Canyon, beyond the Lower Falls, this trail winds
through a forest of lodgepole pine, spruce and Douglas fir. The trail
opens up onto Johnston Creek meadows where spring fed pools of
striking colour are found.
Distance: 11,8km / 7 miles, loop trail with spur at the far end."

A couple of the sites I've found have an elevation layer and GE itself
has elevation data too.

Can . . . you . . . see . . . the . . . trails . . . on . . . GE?

If so, you can map them all, and then pick the ones you want to use
when you are there.

The point that you missed was that MAYBE you can map them ahead of
time from GE - you do not need to walk them first to get the tracks as
you mistakenly thought!

But please don't repost anymore just to answer me - I'm done here.
