Recently, during the Standard Chartered Hong Kong Marathon 2012, a 26 years old half-marathon runner collapsed because of sudden cardiac arrest just after he had passed the finish line. He was brought to the hospital and pronounced dead. This is the second case in the history of marathon races in Hong Kong. Each year, more than 20,000 people participate in full marathon or half-marathon races in Hong Kong, and this number is ever increasing. Reports of sudden cardiac arrests have generated concern about the safety of this activity. Intense discussion was aroused among laymen with regard to the need for routine screening prior to participation in marathon races.
