Hi Bri3626 !
I have found running is very effective to get rid of stress.
The coolest way to run IMHO is to run "at random". Forget about running in circles with the rest of the crowd : just go primitive and find your way in the woods or something.
There's a post by Coine about that in the training Forum : "Running through the woods".
It's much more difficult but it's so much fun you don't realise
