Course:


The race course is a 2 mile loop around beautiful Sparks Marina. Total elevation gain is 29 feet. The course is paved and lighted so no gators or headlamps are required. Two real restrooms are along the course and porta potties will be near the start line. We will not count partial laps. So, know your split time toward the end of your race and do not go out if you see you cannot finish the lap before your race ends.

Aid Stations

We will have a fully stocked aid station at the start/finish line providing the usual aid station fare (including Hammer Products) 24 hours per day and real meals during normal breakfast, lunch and dinner hours. We are cupless so bring a cup for your cold drinks with your name or initials on it and leave it at a table at the aid station. We will provide hot cups for soup and hot drinks at night.

Pacers and Timing


One pacer at a time is allowed during the entire event. No bikes, please.


Your time and distance for each completed lap will be recorded automatically using an electronic chip based timing system. You will be issued a timing transponder/chip. It is the runner's responsibility to have the chip on their person at all times! Laps done without a chip are not counted by the timing system. There are no exceptions! A secondary timing system will be placed halfway around the track to verify laps completed. Up-to-date lap totals will be displayed instantaneously when runners cross the start line. Additionally, updates will be broadcast to the race website periodically during the race. Invite your friends to watch your progress online during your run!
