Pi Day River Rotation - Half Marathon and 5K

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

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.

The Pi Miler, starting at 8 am, is two short loops of 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 counter clockwise and clockwise directions.

There will be a single aid station located at the trail head. Runners of the Half will pass the aid station twice, at 5-mile intervals. Water, sports drink and fruit will be available at the aid station.

After the race, enjoy some homemade pie at the finish line!

Finishers of the River Rotation Half will receive an outdoor, durable, magnet with the date and their time.

Frequently Asked Questions

Will there be photography?

Photography on the trail will be by Mile 90 Photography. http://www.mile90.com/Race-Photos/Pi-Day-2014

Can I bring my non-human companion?

The River Trails are not that wide, we ask that if you can leave your pet at home, please do so. If you do decide to run with a four legged pal (or a parrot?!?), please make sure they are on a leash and do not get in other runners’ ways.

Can I run with headphones?

Headphones are allowed, but if you use them, please only have one ear bud in so that you can hear if a course director or fellow runner needs to tell/warn you of something.

What about parking?

The parking past the levy will not have access from 7:45 a.m. until 8:20 a.m. during the Pi Miler start and again from 8:45 a.m. –9:20 a.m. for the beginning of the Half Marathon.

Both races start at the levy gate into the park, run through the parking lot and on to the trails. Please be mindful of that when parking.

Where do the races start? Where do I check in?

Both races start at the gate on the levy.

Check in and the finish line is a bit Southeast of there in the field.

ALL runners should check in and out of the race.

Check-in starts by 7am.

Wait, what time does my race start?

The Pi Miler starts at 8 am.

The Pi Day River Rotation Half Marathon begins at 9 am.
