Sorry about this.
As you can tell I don't really know much about the whole gpx subject, I don't know the difference between a route and a track*, hence the simplistic OP.
I use a Garmin 305 and it doesn't really seem to care - I put a gpx into bikehike, fiddle with it to add what I want (turns in the dark, controls etc), download it as a TCX file, put it into the device as a garmin course, then follow the breadcrumb trail. It's incredibly simple and I haven't really looked at a routesheet all year. It beeps when I leave the course or when I get to a course point, at night I can make it light up at turns, but it doesn't have any intelligence or routing capability. I assume I'm in proprietary Garmin land here, but it works for me.
Anyway, back to the point. Manotea has kindly offered to turn the routesheet into something that should work, Paul D is also doing his own and he is an etrex user, so we should arrive at something suitable. My original bikehike files were bigger than the AUK 200 Kbyte limit, which is why I thought it was a good idea to reduce the number of points in the first place. If anyone would like one of my originals (which should hopefully load into bikehike or something similar to customize) then PM me.

at risk of this coming out all wrong, I don't really want to know either, I have a solution that works for me, I'd just like to provide riders with a "vanilla" file that they can customise to their own preferences
