The Mighty Mother’s Day Du is not just for Moms! This event has been a mainstay on the multi-sport scene for over 20 years. With a very flat 3-lap bike course and a mix of trail and road on the run, it’s a fun way to start the day!

1st Run: Athletes enjoy a road start and enter the trails of mixed terrain.

Bike: Three lap ride on park roads that will be closed to vehicle traffic for the duration of the event.

2nd Run: Another loop on the, now familiar terrain of the 1st loop. There will be a water stop at the beginning of this loop.

Bikes allowed: Road bike, time trial, mountain bike or hybrid. Sorry, no tandem or recumbent bikes.

Time Trial: Participants will start 20 seconds apart and cycle three laps on the closed roads at Heckscher State Park.

For the best results with photo tagging and searching, the photographers need to clearly see your bib# when taking photos. This will greatly improve your name & bib# photo search results.

Please have your bib# placed on 

1-on the front of your bike helmet
2-on your bike front tube closest to the handle bars, for easy side viewing
-and on the front of your chest or abdomen, not on your back!

Again, make sure your bib# is clearly visible for the camera!

RunSignUp has the ability to search for your photos by Bib# or Name. Try it, it’s easy.
The photos can also be found by going to your results page on RSU, and clicking on the small photo icon under your name. The bib# tagging is done automatically by google software and is not always perfect. It is being worked on by RSU, to make it better.
You can also manually add missing bib#’s yourself, so don’t hesitate to help when the software missed it!
