The Hawthorn Half Day Relay and Ultra began in 2006 as a 12-hour event for Teams of 6, Teams of 2 and individual runners. In 2015 we added a 6-hour event for Teams of 3 and individual runners. Both events start at 7:00 a.m. There are multiple divisions and age groups in which you can compete. Runners compete on a 5K loop throughout the day. Once there is less than 30 minutes to go in the race, runners will only be allowed to go out on the "short course"; 1/2 mile for both 6-hour and 12-hour events. Runners must cross the finish line prior to time expiring in order to receive credit for that lap. The winners in each division/age group are those who complete the most miles in the allotted time.

We provide cold Nuun Hydration, cold water, salty snacks, fruit, nuts, etc. throughout the day. Updates will be provided through a live online link and QR code access to that link.

All participants receive a custom finisher's medal. Awards for the 6-hour race will be presented around 1:45 p.m. After the 12-hour race there is a meal provided for the 12-hour participants and awards will be presented around 7:45 p.m. You must be present to receive awards. If you drop out of the race early, please see the crew for your finisher medal.
