Course Information:

Duathlon first leg Run course - 3.3 miles - Out, a counter clock-wise loop, and bakc course. 

Swim for half - 1.2 miles - in water start 

  • Expected water temperature around 74 degrees.  Wetsuits allowed and optional if water temperature is 78 degrees or less taken on race morning.  Come prepared with a wetsuit just in case. 
  • Swim Cut Off Rule.  All participants are expected to be able to complete the swim discipline maintaining a steady consistent stroke and able to maintain on course.  Lifeguards are provided for emergency situations and to prevent swimmers from drowning.  Any swimmer who is in constant need of aid from lifeguards along the swim is considered to be a hazard to themselves and other swimmers and has not prepared properly for the race (this includes breaks, and redirection on course).  If a lifeguard at any point feels an athlete is taking too much attention, the lifeguard reserves the right to remove the athlete from the race.  This removal will result in a DNF (Did Not Finish) from the entire race (the athlete will not be allowed to compete in the bike or run) at which point athlete must hand in their timing chip to lifeguard or designated staff person. 

Bike for half - 56 miles - Flat and Fast.   Back to the one loop course to be posted soon. 

Run for half - 13.1 miles - New for 2012 as the C&D Canal is under construction by the U.S. Army Corp. of Engineers.  We will utilize most of the same course as the original Diamondman Triathlon when it was first established.  The run course consists of a 6.3 mile out and back course which is completed 2x with a .5 mile start and finish segment shown as a dashed line on course map.  The course is mostly shaded and primarily cross country terrain with some crush and run paths and paved roads.  Please plan your footwear accordingly.  Runners should always stay to the left of each throughout the entire run.  Water, gatorade, hammergel planned at about every 1 to 1.5 miles.
