My practice is getting stronger too. I've reached the point of my training where maintaining flexibility is critical to keeping injuries at bay (and to continue healing my Achilles!). It might sound goofy to some serious practitioners, but the Yoga for Runners is a nice 15 min. way to release at the end of a run. I've used it 5 or 6 times and have already noticed a difference.
The rest of this week should not be too hard; 36 mi., 2 w/o's @ Sportfit, climbing, and yoga...
