After graduating for C25k and doing a couple of 30 minute runs I decided to move on to 5k+. I had read various reports about stepping stone so I was a bit dubious about trying this. But I have to say that I did enjoy it. It did seem a little slow to start but I soon settled into the rhythm. I found the 155bpm a good pace, which whilst I have done that speed before it hasn't been for that length of time so I was chuffed that I kept it up and got up a big hill as well. Then the same with the 160bpm. It felt good to be doing more than plodding but I could really feel it by the end. So my advice to any graduate would be, give it go, at least once, you may be surprised.
