Cancelled Event (updated 7/20)


Special Registration Note (as of 7/9)

At this time we've paused registration for the Thunderbunny Trail Races. We have presented a "COVID-19 Race Plan" to the Athens County Health Department and the Ohio Department of Natural Resources, the permitting agency that we must receive approval from, in hopes that the Thunderbunny Trail Races will be approved. This plan implements event procedures and policies that we hope will gain the approval of our permitting agencies in order for us to have the event, in a safe manner. Earlier, ODNR announced that they revoked all events in ODNR operated properties (such as state parks) through July 15. There is uncertainty about the future of that process within ODNR, but we have reached out and presented our plan to them; we think it's best to halt registration until a more clear answer is given with permitting. If you are currently registered, please know that we have worked and will work on doing what is necessary for Thunderbunny to take place. Thanks for your patience, we will update everyone as soon as more information is available.

Thank you,

Event Description

Back for a 5th edition! - Athens County’s first ever ultramarathon! The Thunderbunny 50K comes to Strouds Run State Park and will show off some of the best trails in the region and give participants a great experience, whether you are a first timer or a trail veteran. The course starts and ends on the famous 3 mile Thunderbunny Trail, and in between runners will complete a loop around Dow Lake and run up and over a ridge to overlook the city of Athens! With the course boasting 95% singletrack trail, this will quickly turn into a favorite for pure trail runners. While showcasing some of the great Appalachian Foothills that Athens is known for, this is also a very runnable course so it is a perfect option for your first ultramarathon or first trail race! Along with the 50K, there will be two shorter course options of 25K and 12K to choose from.

Capacity and Waitlist

Once the 12K registration reaches 300 participants and the 25K and 50K reach 300 total participants regular registration will be closed, but you'll still be able to register for the waitlist until the registration close date.

As runners withdraw from the race leading up to the event, the next person on the waitlist will be notified and will have the opportunity to move onto the entry list.

The next person invited into the race from the waitlist will coincide with what race the person withdrawing was in. (ex. someone from 50K withdraws, someone on the waitlist for the 50K is invited in).

You do not get charged to be on the waitlist, and your credit card will only be charged the entry fee once you accept your invite from the waitlist. You'll be notified via email once this happens, and you'll have the option to accept or decline your entry. We will accept people off the waitlist until the registration close date on the Monday before the race.

To participate in the Thunderbunny Trail Races you are required to complete and sign all waivers. If under the age of 18 yrs old, a parent or guardian must sign waiver form.

Refund/Deferment Policy:
Like most events of this nature and because items for the event are purchased months in advance of the race, the Thunderbunny Trail Races cannot provide full refunds close to the race date, but we follow a refund schedule that will help give a little back to those who need to withdraw from the race. Our "Refund Window" is as follows:
45 or more days before the race = 100% refund
20-44 days before the race = 50% refund

To request a refund:
You must log into your UltraSignup account, then go into your "Registration History". Once you find the race you want to withdraw from click "edit" and then "cancel registration." At this point you'll be prompted to request your refund. The refund will be automatically applied back to your card. Please note that in some cases a bank will not accept a refund back onto a credit card, and in that case the race director will be notified and will send your refund via a check through the mail, once the race is complete.

If you don't have an UltraSignup account, please email the race director and the process will be completed manually.

Deferment Policy:
