I had a bit of a thing with a duff parachute a couple of years ago which ended up with me being on the rat poison for six months.
Basically, you should have no problems running, but be sure and carry a butt pack with a couple of bandages or a big bag of cotton wool, your mobile phone and your card in case of accidents.
Don't go near anything sharp like broken glass, barbed-wire fences, mutts' teeth or my ex-fiancee's tongue and you should be OK.
