Thanx Greg.  IIRC, SRTM is raster data with a pixel with at best 90 X 90 
m.  Even if it were 30 X 30 m, it would still be quite coarse for a 
running path.  Strava.com is overkill for my needs.  For the altitude, 
all I'm interested in really is a way to tag altitudes to vertices of 
locations I know and have them show up as a cross section.   Thanx for 
your pointers.
