• The Boulder Stroke & Stride is a Swim/Run event, also known as Aquathlon.
• The race begins with an open water swim of 750 or 1,500 meters.

• The swim course is a rectangular shape, with participants swimming in a clockwise direction around a series of large orange buoys.
• One lap of the swim course is 750 meters.

• Upon completion of the second lap, 1,500 meter swimmers will run to transition.
