The way I run my pyramids is as follows:
warm up, 1 min fast, 1 min recovery, 2 min fast, 1 min recovery,3 min fast, 2 min recovery,4 min fast, 2 min recovery,5 min fast, 2 min recovery,4 min fast, 2 min recovery,3 min fast, 2 min recovery,2 min fast, 1 min recovery, 1 min fast, 1 min recovery, cool down - so the hard sessions go 123454321 ie a pyramid.
Maybe the one in your schedule is: warm up, 1K fast, recovery,2K fast, recovery,3K fast, recovery,2K fast, recovery,1K fast, cool down
