Tempogression run

Todays run started off as a normal run. My last run was on tuesday and today I needed to run for more than one reason: I needed to get something going in my life other than classes and research; I needed to regularise my runs. So coming back to todays run, I started off at my department and went on along the gilman trail. I have found that I can't run on roads on a regular basis, so the trail serves the purpose of giving my legs lesser pounding when I run. My pace from the start was fast: 7:30/mile to 8:00/mile and then as I progressed I got faster. My return was even faster and at the end, the last 1 km or so, I was touching 6:00 - 6:30 min/mile.
Normally my runs start out slow(say jogging pace of 9:00/mile) and progress to a faster pace as I get warmed up and finish fast - a la progression run. Today's run was definitely a progression run but with a twist..I started fast and the run was fairly intense and was of a shorter duration(tempo run): 22 minutes. So I would classify this run as a tempo+progression run or a tempogression run.
