Im not sure how in shape you are, but I like to do this a few times a week, but you need to do a little homework first.
First I drive a short route out, like 10-15miles then bike the route, and as soon as I return to the starting area, go out for a short 1-3 mile run, then jump rope for about 5-10 minutes. The combo bike/run gives you a nice change up sometimes.
I also swim some too, but I am training for triatholons, and lifting hard, so Im different than alot of hardcore lifters on here.
