Pi Day River Rotation Half

A race for nerds and pie lovers alike!

If you're a nerd, this is the race for you! It's also the race for you if you're not a nerd, but like running and pie.

Trail run on a smooth, fast course with a few hills sprinkled in for fun. This is a three-loop course, alternating between counter clockwise and clockwise directions. There will be a single aid station located at the trail head. Runners will pass the aid station twice, at 5-mile intervals. Water, sports drink and fruit will be available at the aid station. Registered participants receive a short-sleeved technical shirt. After the race, enjoy some homemade pie at the finish line!

Q: What's Pi Day? A: Pi Day is a holiday held to celebrate the mathematical constant π, 3.1415... It is held on March 14th (3/14). Get it? π (sometimes written pi) is a mathematical constant whose value is the ratio of any circle's circumference to its diameter in Euclidean space. -source http://www.wikipedia.org/

Q: If the race is call Pi Day, which isn't on 3/14? A: This year, Pi Day falls on a Wednesday. To accommodate all those wishing to run, we have moved it to a weekend with the closest equivalent, 3/4. (Look closely and you'll see it!)

Q: Why is the name of your race so long?? A: 1) For enhancing the nerdiness of the race. The abbreviation of the title is πR², the area of a circle. 2) Alliteration is fun. River Rotation.

Q: Why isn't the race 3.1415... miles? A: Because I wanted it to be longer darnit! More fun. :)
