This will be a 10AM mass start to an area of the map called the "Box".  You can visit the "Box" controls in any order you wish (like a score-o). The total number you are required to visit will vary depending on your age and sex. After completing the box, you transition to the "Chase", which is a regular point-to-point course to the finish. The total distance, including both the box and the chase, will range between 3.0km (W70+) and 6.0km (M21+), with 1% climb. Course closes at 1PM. There will also be a 2.5km yellow course at 10AM. 

 
Ironwood Park is located near Old Tucson, where many western movies have been filmed. It is mostly open desert with many dry streambeds and shallow rentrants, with amazing views of the mountains on the skyline. You can recognize the skyline in several older movies. There is a small set of low hills on one edge of the Box, but only the M21+ runners will be going there.
