Pi Day River Rotation - Marathon, Half Marathon and Pi Miler

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 is back for its second year! Starting 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. Water, Tail Wind, Honey Stingers, fruit, and other items will be available at the aid station.

After the race, take in the second half reason for the race and enjoy some homemade pie at the finish line!

All finishers will receive a race shirt, finisher's award, and car vinyl with distance. This year we are working with Trailheads again to bring a custom cold weather running cap for your swag.

Pi Day hoodies will be back.

Frequently Asked Questions

CUPS?!

In an effort to continue the Lawrence Trail Hawks mission of Kindness to Life and Land, we are requiring runners to bring their own hydration devices. We will provide a few community cups at the aid station if you are brave enough to use them. 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. Thanks!

What's the situation with parking?

There is parking available past the levy, however, please be aware of the time, as access to this area will be restricted during race line up and start times. If you park on the road into the park, remember (and tell your supporters as well) that runners will be coming down this way (the red start arrow). Do not block the road, or keep your doors open. If you park on adjacent streets, such as Oak St, please remember that people live there and they will need to get out of their houses too & traffic should be able to flow down the street. There will be some No Parking signs on one side of Oak to help with this. 7:15 am – 7:40 am Access to lower parking lot not available by car 8:20 am – 9:15 am Access to lower parking lot not available by car

Music/iPods/Headphones

We ask that you leave your headphones at home. We strongly discourage the use of headphones as it detracts from the whole trail experience as well as limits your interaction with others and your environment. We have found historically that runners wearing headphones tend to get lost more frequently, miss trail directions and are unaware of other runners trying to pass. If you must wear them 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. If you choose to ignore this rule you run the risk of going off course, going the wrong direction, going extra miles, etc. PLEASE pay attention to our volunteer course directors and fellow runners!

Can I bring my dog?

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, or bring along for cheering, a four-legged pal (or a parrot?!?), they must be on a leash so they do not get in the way of other runners or bother other participants/volunteers. There are some people that are afraid of dogs, no matter how friendly your's might be. :)

Trash

Please abide by the “take out what you bring in and leave nothing but footprints” moto. Leave all garbage at aid stations. Those found to break this rule will be disqualified.

Timing?

Chip timing this year provided by The Timer Guys.

Are we going to have awesome photos?

OF COURSE! Because Mile 90 will be there on the trails and finish line taking pics!

There is a forecast for weather...

We don’t usually address the weather since we get snow, ice, sleet, and cold – and that is what makes this race “fun!” As in the past, this year there is a chance of rain and/or ice and/or snow race morning. If the trails aren’t runnable, we will have the race courses on the levy, but that is only if the trails are un-runnable per the “Trail Guardians.” If there is lightning within a mile of us, we will delay the race/pull runners from the course (if possible) if it’s in the process, until we are clear. As you’ll see throughout, your safety is important to us. Keep an eye on the Facebook page and your email, as we will be contacting you both ways should anything change.

I'm confused on what time I start.

I left the race, but I think I won an award.

That's awesome...and a little sad. Awards for each race will be given as runners come through the finish line or in the finisher's tent. You must be present to receive an award.
