LDP is a fantastic discipline - - those folks cover huge distances, moving fast, and occasionally uphill, without ever setting foot to pavement. But the equipment is very specialized. If you're looking to incorporate pumping into general campus cruising, you probably don't want to go that route . . . yet.
Gessemer's article is a classic.
Shorter is easier too, but know that any setup that turns well at a slow speed can be pumped - - it's just a matter of efficiency.
I'd suggest you start on a slight grade, and practice sustaining a rhythm of tight cross-under turns. Then start to put more energy into it and feel how the turns add speed. Next take it to the flats, and try the same thing there (with a push or two to launch you).
