I do lots and lots of gps stuff professionally and for fun.
I have found, at the moment, that Google kml files are the easiest for sharing.
I think this will surpass gpx if it hasn't already. It also gives folk the chance to preview the stuff on their computer if they have not paid for any maps with their gps. Also works for windows, mac, linux, android, iphone etc...
I did this recently for the Wild Endurance race in the Blue Mountains:
