+1 on the self-myofascial release (foam roller, Stick, rolling pin, lacrosse ball, etc) and compression hose.

Also no one's yet mentioned recovery nutrition, which I think is the most important part of it. The window starts closing 30 minutes after your workout ends, and closes in 2 hours. So, as soon as I get back from a long run, I'm fixing my recovery shake with carbs to replenish muscle glycogen and protein to help muscles rebuild. I stretch *while* I'm fixing and drinking it. Then I *try* to get a full meal within 2 hours.

And yeah. It's pretty well established that no matter how fit you are, everyone's recovery time increases as we get older. It'll mean different things to different people, but none of us in our 50s and above are going to be able to get the greatest benefit by working out with the same frequency as we did in our 20s and 30s. You hear people say "I've been doing the same thing for the last 30 years," and that's great that they can still do it and not get injured, but odds are they'd be even stronger and faster if they took more recovery time.
