I am running a study on public awareness of the risks of marathon  running, and the public's willingness to take precautions against these  risks.

This Google survey is only 10 Yes/No questions and will take less than!a  minute. This study will be submitted to the American Heart Association  if we can get over 1000 responses. Thanks for your help.
