I would suggest to create a new point shapefile, change it to edit mode, select the waypoints layer by layer with rectangle , and paste them into the shapefile layer.

You can do this with ArcGIS 10.1.
run GPX to Features tool (converts GPX files to points features class)
run Points to Line tool (converts points FC to line FC)
run 3D Analyst tool: Stack Profile (creates a table of elevation AND with the optional output graph, provides the profile as a graph)
So you'll need ArcMap 10.1 basic /w 3D Analyst.

For a Python approach, try gpxplot available from code.google.com. The script is available here and the online interface is located here.
Try using GPS Visualizer. The profile tool looks like what you may be interested in.
Or, Maplorer: View GPX file on map + elevation
