On the plus side, I find that the vapour from Deep Heat makes my nose less congested.
As the others have said, no great benefit from using Deep Heat before running, but probably no harm either, so if it feels good, do it.
A good cool down - gentle jog and a stretch - after a hard run is good to flush out any lactic acid that's still swilling around there. But remember, the stiffness is due to the fact that you have done some damage to your muscles, and it's the repairing of that damage that makes your muscles stronger. Your body is giving you a gentle warning not to do too much until it's healed itself.
