For younger runners (and their parents): This year, in addition to the Pi Miler, which is 3.14 miles, there will be a Fun Run during the 5k for children 12 and under! This is a great alternative for runners who might not be ready for a longer run, or who might not be comfortable with a portion of the run taking place on Little River Turnpike (though Fairfax County Police will be closing one lane of Little River Turnpike and directing traffic during the race). Parents are welcome to participate in the Fun Run along with their kids!


What is the Pi Miler? The Pi Miler is an annual 3.14 mile race (matching the first three digits of pi) begun six years ago by the Class of 2013. This year marks the9th annual running of the TJ Pi Miler, but the first one to be run at TJ since 2014, due to the ongoing school renovation. The race generally coincides with Pi Day, March 14th, a worldwide celebration both of the mathematical constant pi and the joy of studying mathematics. In 2015, the race actually began at 9:26am on March 14th, so that the start time was 3/14/15 at 9:26 (to coincide with the initial digits of pi being 3.1415926). This year, the honor to host the Pi Miler belongs to the Class of 2020.
