Email is the preferred method of contact. The race information line contains recorded information about the race and a chance to leave messages. Messages are retrieved from the hot line on a regular basis, particularly as race day approaches. Please use only one method of contacting us -- either by email or by phone -- in order to avoid double work on our part.
