Last year, Westin introduced its lending gear program that, for a nominal fee, gave hotel guests New Balance shoes or clothes so they could go out for a run without having to worry about not having the stuff they need. (Shoes feature disposable insoles, in case you were worried.) The program, called runWestin, also offered designated conciereges at hotels that lead runs throughout the area. Now, the hotel kicks it up a notch, with a special vending machine, activated via Twitter, that distributes New Balance gear. When you tweet from the machine, you include your size and gender -- women also get running bras -- and you get the gear free. The machine will be introduced at the Westin New York on 42nd Street on National Running Day, June 4.
