Pi Day River Rotation

It's not just a Half Marathon, it's a Half Marathon with Pie! Pi Miler -Pi to Pie

Trail run on a smooth, fast course with a few hills sprinkled in for fun.

The Pi Miler, starting at 7:30 am, is 2 loops of different distances, totaling 3.14 miles (just over a 5K).

The River Rotation Half Marathon, starting at 9 am, is a 13.14 mile three-loop course, alternating between counterclockwise and clockwise directions.

The Pi Day River Rotation Full Marathon will start at 8:30 am, runners will take a short lap, and 5 longer loops bringing you to 26.21 miles.

The Pi Slam is the original combo race for the Pi Day Races for those wanting to add a little more distance (and race swag) to their day. It is a combination of the Pi Miler and the Pi Day River Rotation Half Marathon. The Pi Slam will begin at 7:30 am and follow the course for the Pi Miler, and will begin again at 9:00 am with the Pi Day River Rotation Half Marathoners, following the course for that race.

The Ultra Pi Slam is for those wanting to add even more mileage. It combines the Pi Miler and the Pi Day River Rotation Marathon. The Ultra Pi Slam will begin at 7:30 am and follow the course for the Pi Miler. They will then toe-up again at the starting line at 8:30 am with the Pi Day River Rotation Marathoners and follow the course.

For those who can't get enough, or want to try out ALL the distances, The Answer to Everything is for you. The Answer to Everything (42s) will begin at 7:30 am with the Pi Milers and follow the course for the Pi Miler. They will then line up again at the starting line at 8:30 am for the Pi Day River Rotation Marathon. When 42s complete the marathon, they will check in with one of the RDs, where we will line you up at the starting line for your own personalized start time to begin the Pi Day River Rotation Half Marathon.

For all distances, there will be a single aid station located at the trailhead and an aid station at the finish line. Runners in the marathon and half-marathon will pass the aid station at 5-mile intervals.

Drop bags can be left at both aid stations. Water, Tailwind, Honey Stinger products, fruit, and other items will be available at the aid station.

After the race, enjoy some homemade pie at the finish line with your custom-distance finisher's fork!

Timer Guys will return with chip timing.

Cupless Race!

In an effort to continue the Lawrence Trail Hawks motto of "Kindness to Life and Land," we are requiring runners to bring their own hydration devices. We will provide a few cups by the water coolers at the aid stations if you are in need. There will be some cups available to runners for hot beverages only. Please help us with this transition by ensuring that you bring a hydration device, no matter what distance you run. A limited number of 16 oz collapsable hot/cold cups will be available for purchase on race day for $15.

Some races give you hardware. Pi Day gives you flatware.

All finishers will receive a finisher's award and car vinyl with distance.

SWAG

Keeping with the winter run tradition, we offering locally, hand-made winter hats in everyone's race packets.

A limited number of Pi Day hoodie jackets, long sleeve tech shirts, and short sleeve t-shirts will be available for purchase on race day. You can also order early with your registration to ensure you get the size/style you like.
