3+ mile run on grass

Today I ran on the really flat grass by the indoor tennis center. It's a bunch of soccer and softball fields all together so it's a pretty roomy area. And although doing laps like that made for a pretty dull run, it was helped by the fact that I ran for 32 minutes with little difficulty. I might have had one more set in me but thought better of it and stopped. So I don't know if this means things are improving or just that the grass reduced the irritation, but I'll take it :-)
