Has anyone got an opinion on what map system is good to use on a pc. I presently use trailguage which is a free download for the bacic system and allows for all my runs over the mountains to be measured accurately - the registered version ($19) even works out height gains etc. The only downside is that you need to scan the map in question beforehand and therefore if you run in a lot of different areas it takes a lot of time and uses up a lot of the computers memory. Does anyone know about the Anquet maps (£32.99) or the Memory Map discovery range (£39.99). What will these programmes do?
