seriously long day at the computer today, i Have been measuring and marking my approximate days ends onto my maps in increments of 17 miles, usefully google earth could import my planned gpx route in very easily so i'm certain that my measurments clicked into G Earth are reasonably accurate.
Google also made it easy for me to create an image of my entire walk which you can now see in the right hand bar.
Enough computer for today. time to feed alfie anyway :)
