hi all, im really struggling with this and im sure it should be simple,

i use my tracks to gps my walks, i then upload them to google maps(now seems to be called google fusion) so i have at the mo 5 seperate maps, great so far, but i want to have a map that shows all of my walks at the same time and i cannot figure out how to do it, can anybody give me a walkthrough please,

cheers
