I am taking part in the Frozen Bonzai half marathon in New York in December around Central Park. I have never run in possibly extreme cold conditions and I am seeking advice. I am not good in cold weather at the best of times but know I heat up quite a lot when running in british now weather just in shorts and singlet. My concern is buying all the winter kit to find that my usual, shorts and singlet, with a garbage bag would have sufficed and getting part way through the event to be toooo hot.
I know it is very different for each individual but if any one has run this event or has any advice I would be very grateful to hear your thoughts.
