from runningmania.com -- Stiff Legs

Found this on www.runningmania.com forum.

After waking up the next morning:

If you can make it down the stairs but legs are stiff:
-You're ok, it'll loosen up after a couple of k on your next run

If you need to hold on the railing going down:
-Better back off, do a shorter easy run

If you need to hold onto the railing with 2 hands:
-Take a day off...

If you have issues getting out of the bedroom:
-Maybe 2 days off...

If you can't get out of the bed:
-Sell the bib
