But you shouldn't need it. You will notice that:
1. There's a route point (Note - not waypoint) for each turn on the route sheet - so your GPS will beep, light up and get your attention when a turn comes.
2. There's a saved track for the route, in bright green which is precisely the route that the Follow Road route should take you.
Are you using Bikely to plot the routes to begin with, or what is your method? Personally I just make up the route (usually) im Memory Map, save it as a .gpx, and bung it on Bikely when I need others to see it.
This is what happens when I've downloaded some of Pluck's routes from Bikely - there have been 100s of waypoints, but there has been a 'proper' track underneath.
How do I improve on this?
I use Mapsource to create my routes. Here is what I do:
1. Interpret the written routesheet, and drop a User Waypoint for each control (eg "001 - HQ", "021 - CON
1") and instruction (eg: "078 - L TL", "089 - SOX", "099 - INFO R") onto the map. I use red flags as markers for the controls, regular black dots for the others.
2. Join the waypoints to make one or more routes. If (like the Norfolk B-Roads 200) the route is a figure 8, I'll probably do it as two routes - one for each loop.
3. Save this as a .gdb file (Version 2), then open it with WinGDB and convert the routes to tracks. I copy and paste these tracks back into the original gdb, so I now have a file with a load of User Waypoints, one or more routes, and one or more tracks (one track for each route).
4. There is a 500 track point limit per track on the Etrex Vista, so if (as is likely) the tracks have too many points, I split them into separate tracks each up to 500 points long, and also set the track colour to bright green.
5. Now I save this as a gdb file (for posterity) and a gpx.
6. I run a utility to strip all but the Control (Red Flag) User Waypoints from the gpx. I can do this because Mapsource rather helpfully copies the User Waypoints into the routes as route points, retaining the original instruction text.
And there you have it - a compliant gpx that works fine for "Off Road" navigation.

1 I used to use "CNT" for "Control", but people I shared my routes with would fall about laughing whenever we approached a control - but I could never work out why .
