running bare - I should imagine that this is the best policy. To stop the treadmill mid session, hold your hand up and shout "OK. I admit it. It was me," could actually win you less friends. Perticularly if, by any stretch of the imagination given the potency you suggest, your foul emmission had not pervaded their nostrils. You could, in their eyes (assuming their not streaming), be admitting to any number of heinous acts.
