April 3, 2020 

We know that many of you have had questions regarding whether the 2020 Hawthorn Half Day Relay & Ultra would still be held on May 16th. We had hoped to still hold the event but given the ongoing concerns with the COVID-19 outbreak, we have made the extremely difficult decision to cancel this year's event. 

Our entry form states, "NO REFUNDS", but these are extraordinary times. Therefore, we have taken into account all the expenses incurred to date with preparing for the race and have set forth the following two options. 

1)      Apply 100% of this year's entry fee to either the 2021 or 2022 races. Even if there is an increase in the 2021 or 2022 entry fee, you would pay nothing. 

2)      Provide you a 50% refund of this year's entry fee (registration fees are not refundable) and the remaining 50% would apply to the 2021 race. Should the 2021 entry fee increase, you would owe 50% of the 2020 race fee plus the amount of the increase.

Emails have been sent out to all individual participants and teams. If we do not hear from you by May 16, 2020, we will automatically apply option #1 above. 

Should you have any questions please email Mark at



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"; 1K for the 6-hour event and 1/2 mile for the 12-hour event. 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 that complete the most miles in the allotted time.

We provide cold Gatorade, cold water, salty snacks, fruit, nuts, etc. throughout the day. Updates are provided approximately every hour, starting at 10:00 a.m. We normally have a massage therapist onsite beginning around 1:00 p.m.

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.


2019 RECAP

Once again, weather played a part in the 2019 race. It was hot day for May, with a high of 87 degrees. A few late afternoon clouds and a strong breeze helped, but the weather conditions definitely added to the challenged of competing in an ultra event. Even with the heat, it was a great day for racing, the course was in great shape and everyone adapted to the conditions. A total of six records were broken in the 6 event. Four in the individual race and two is the team race. (see below)
