Some easy treadmill running to warm-up and cool-down plus weights.
Lifted hard. I have discovered that I'm getting old. I have been consistent enough in my workouts over the past three years so that I can notice subtle differences. I'm not saying that I won't ever be able to establish another post-40 PR, just that it's going to be harder and I'm going to have to pick my races well and do a better job balancing training and racing.
