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. https://spreadsheets.google.com/view...ZUMlE6MA#gid=0
