Too many points in my track.

I am trying to plan a route or track for a mostly off-road motorcycle ride in Utah. I'm trying to keep the waypoints or points to a minimum, but somewhere trying to load it in to my Zumo 590, it has put over 5200 points in a 180 mile ride. Don't know if this was when the Zumo was asking me to put it in Trip Planner, which I didn't want. I want to stay in Tracks, but it only would take 1 day in tracks and then asked to put the next in Trip Planner and convert it to a route. I am also having trouble with it showing that it saved the rides in my SD card, but when I turn on the Zumo, they are not in there. Trying to redo the ride days so these points are not in there.  But with riding dirt roads, it's hard not to put too may points in. I'm stumped!!!
