I have a GPX file of a bike race I am going to be doing, but would like a printed map to carry in the vent I have a GPS failure or just need to verify something along the way. HOw can I print just the map large enough to use?
Import your track into MapSource or BaseCamp with the background map you want visible. You can print from either of them.
Or this online: http://www.gpsvisualizer.com/ You could dump it as one of many formats. Heck, make a wall size map of it! :)
