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.


Registration will open February 6

Those who rolled their registration over from last year will priority registration.


Our goal this year is to have a real race! We’ve made some changes to the schedule and format of the race to help ensure that we will be able to hold the race in person. We need another week to get registration set up.


In order to reduce the number of runners gathered together at any one time, yet still allow as many runners as we can to join the fun on the course, we have split the event over two days, Saturday, June 26 and Sunday, June 27. The 15.5 hour and the 6 hour sunset runs will be on Saturday with the normal start times. Sunday will host the 8 hour and the 6 hour morning run. The 8 hour will start at Sunrise. The 6 hour will start 30 minutes later. This gives time for one group to clear the start area and then gets the second group off before the first runners complete their first lap. Initially, all events will be capped at 48 runners. Once we get closer to race day, if things improve we may be able to raise the limits.


To help avoid having to process refunds, everyone registering will be put in a wait list status. No charges will be made to your account until we have an official go ahead.


We are also looking at securing a backup alternate location in the area just in case the situation changes at the University.

We hope to have an update on the Wolf Run soon.

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

Registration for the 2021 ultra events opens Saturday, February 6, 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 and Sunday'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.
