Hi Phil

I use a GPS and followed a track.

I plotted the track using a lot of different methods:
1. I made an educated guess where one track was by spending ages looking at Google Earth and following ridge-lines. I was out by a couple of hunred metres in one spot, but we found the track easily enough on the bikes.
2. I have a copy of Qld Govt “Sun Map” digital map collection as was able to plot some of the course using this.
3. I’ve ridden some of it before and used some of my own GPS plots.
4. I spent ages searching other people’s rides on Garmin Connect, found a guy who had done a similar ride, and got some ideas from him. (That’s not always optimal as you can end up making the same mistakes they did).

Thanks for asking this as I’ve been thinking about doing an article on how to plan your own adventure. I’ll expound on some of these methods in that article.
