Titletown Ultra Series is back!

BUT...we have a new name.

We are now

Dawn to Dusk Endurance Run.

Don't worry. It is still the same great event you have come to love/hate. The same supportive staff that you have come to expect along with another great batch of swag. And yes, the watermelon will still be at Aid Station 1.


We plan to open registration February 1, 2021 for our 10th (almost) annual race. We hope that you already have us penciled in on your race calendars and look forward to seeing everyone in person in June!

It will take us a while to get our name changed everywhere. Please be patient. If you don't find us under one name, check the other.

Your Dawn to Dusk Endurance Run team,

Ann, Scott, Jeannette and Shannon 

June 25-26, 2021

Green Bay, Wisconsin


Join us June 25-26 for a weekend of ultra running fun! We kick things off on Friday, June 25, with the Wolf Run 4.75-Mile Evening Trail Run and continue Saturday, June 26, with FOUR ultra events: our newly rebranded Sunrise 6 Hour, the 8 Hour, the 15.5 Hour Summer Solstice Challenge, and our brand-new Sunset 6 Hour! Choose the one that is right for you! Or, sign up for one of the ultra distances AND the Wolf Run as well!


All events take place at the University of Wisconsin Green Bay campus, starting and finishing at the Shorewood Golf Course.


Registration for the 2021 ultra events opens Monday, February 1, 2021!


  • Timed Events - With the Sunrise 6H, Sunset 6H, 8H, or 15.5H, you run as many laps as you want within the chosen timeframe. Results are calculated based on the number of laps completed. Stop and start as often as you like! Note: The Wolf Run is a casual, one-loop event that must be completed within two hours.

  • 4.75-Mile Trail Loop - Course is 95 percent trail, consisting mainly of crushed limestone and wood chips. Course is flat with some rolling hills.

  • Fully supported! We have three aid stations on the course for Saturday's ultras, including our famous watermelon station! The Wolf Run will have one water station halfway through the route.

  • Swag! All of Saturday's ultra participants receive a custom stoneware mug from Sunset Hill Stoneware in Neenah, as well as a short-sleeve tech shirt and a 10L 'Dry bag'. Wolf Run participants will receive a cotton t-shirt.

  • On-site massages will be offered on Saturday only, courtesy of Christine Wolf of Restore U Solutions.

  • Money raised will go towards the Cofrin Arboretum and Girls on the Run of Northeast Wisconsin.
