The swim takes place in a lake with no current and generally warm water; water temperatures may exceed 78 degrees and wetsuit allowance is decided on race morning. The Olympic bike is described as flat to rolling. The Olympic run follows a shaded bike trail through park woods with rolling hills. The Half Iron bike course uses two loops and has Deer Park 700 ml water bottles at the mile 24 and 39 turnarounds; the Olympic and Sprint courses have no bike aid. Run aid stations provide water and Gatorade on two tables, and courses pass aid stations multiple times depending on distance.
