Swim Course Map

The swim portion will be ~ 540 yards of open water in the natural, spring-fed Forge Quarry with a time trial start from the dock. The course will be a rectangle, starting from the dock, swimming clockwise, with three right hand turns at large buoys.  The swim portion will finish and exit on the dock on ladders. The dock will have two way traffic on it with swimmers lining up to start and athletes exiting the swim headed to T1. Please stay to your left at all times on the dock.  


Bike Course Map

The bike course is a 10.7 mile route of two loops on a lollipop style course. There is a short, approximately .3 mile section that is the stick on the lollipop, then a ~5 mile loop that will be ridden twice. The bike course is on crushed limestone trails and some gravel roads. It is flat and not technical but will have a few ruts, bumps, small hills, several sharp turns, wooden bridge crossings, and loose gravel sections.  


Run Course Map

The run course is ~3+ miles on mixed terrain, including crushed limestone and a section of MTB single-track trails. It is mostly flat, but will have a few technical and small hill sections, including dirt, rocks and mulch covered trails.


Transition: Transition will be located in the lawn area by The Mount within the park. It will be a  short ~500 foot run from the Swim exit to T1 on a carpeted surface. Bike racks will be organized by wave / bib number, but bikes will not be assigned a specific space.
