I don't stretch as I've found over the years that more stretching = more injuries for me.
On the other hand, 45 minutes of daily foam rolling, massage sticks and lacrosse balls do seem to help me. I started rolling my legs and back out a few years ago and it seems to help me to recover when I'm doing lots of hard training. I've had no knee and IT band problems since I started rolling every day, something I used to struggle with. I like the Rollga and Trigger Point rollers.
