As most readers of these forums are aware, recent studies have brought into question the benefits of intensive running and endurance-type exercise in terms of health and overall longevity. To help clarify some of these issues, we are conducting a survey of training characteristics and health habits in recreational and competitive runners and endurance athletes over the age of 35. If you meet these criteria we invite you to participate in our online survey. It is 45 questions and should take less than 10 minutes to complete.

The survey can be accessed at:
