The only change I would make on the last page is track up as opposed to North up. Track up means the map rotates to your direction of travel, like most car sat navs.
thank you so much. I've come across people mentioning ridewithgps plenty of times, feeling a bit of a muppet now. I can probably find my way from here (ba-dim-tush)
Ride with gps has what I and many others think is just about the best routing algorithm for road cycling.
