In the past I've been using
BikeHike to record routes I've taken running / biking off road. The fantastic thing about it was the dual view of google map / aerial pic and OS map. So where info was not shown on one, it would usually be on the other.
Trouble is they've stopped letting you record your routes now (no idea why) which was actually the most important feature of all from my, not owning a gps, point of view.
Gmaps Pedomter still lets you record but obviously without as much info on the base mapping, it's harder to be accurate when you head for the hills.
So, anyone know an alternative i can use whilst i wait for the econmy to pick up so i can eventually afford a gps unit?
