Welcome to the Thunderbunny Trail Races
Experience some of the best singletrack trail Ohio has to offer and take your pick of the 50K, 25K, or 11K!
Join us for Athens' first and only ultramarathon!
All races on Saturday, May 10, 2025
The Thunderbunny 50K at Strouds Run State Park shows off some of the best trails in the region and gives participants a great experience, whether you are a first timer or a trail veteran. The course starts and ends on the namesake 3 mile Thunderbunny Trail, and in between runners will complete a loop around Dow Lake and run up and over the "Athens Ridge" to overlook the city! With the course boasting 95% singletrack trail, this is a favorite for trail enthusiasts as it provides smooth and flowing singletrack. 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 are also two shorter course options of 25K and 11K to choose from, both running on the same great trails as the 50K.

50K and 25K Cutoff Information:
The course cutoff for the Thunderbunny 50K and 25K is 9 hours. Please view the 50K and 25K aid station charts on the course information pages to see a detailed chart of these cutoff times. The 25K cutoff will coincide with the 50K cutoff times. Both races cutoff requirements will begin at the Dow Lake Dam Aid Station.
Please note that the cutoff times are when aid stations will pull you from the course. Please respect the organizers decision of cutoff times and understand these times when entering Thunderbunny. If you arrive at an aid station after the cutoff times you will be told to stop the race, and will be transported back to the finish line.
11K Cutoff Information:
We do not have a hard cutoff for the 11K course; with the race starting at 9:00AM on Saturday morning you will have plenty of time to finish the 11K course no matter what level you are at or what speed you plan on going. It is great for hikers! 3 hours for the 11K is 24 minute pace per mile, and 30 minute per mile pace for 11K is still under 3:30 - this will give most people the ability to finish before 12:30PM.

Race-Day Parking
There is ample parking at the Strouds Run State Park Beach Parking Lot, between a 1/4 mile and 6/10 of a mile walk to the starting area at the campground. When walking to the start/finish area, please watch for traffic on Strouds Run Rd. We will have this patrolled.
With that said, SEOTR still recommends a couple of ways to make the parking lot less crowded and easier to navigate on race morning.
-
Carpool with friends or family who also plan to be at Thunderbunny.
-
If you are camping in the Strouds Run campground, walk to the start/finish area (1/4 mile)
Below is a picture of the parking lot area at the Strouds Run Beach to help you get familiar with the area (the orange dotted line denotes the walking route to the starting area).
On-Site Camping and Area Lodging
Group Camp Option ($5): Choose this option during checkout while registering. You can choose to camp at the group campsite in the Strouds Run State Park Campground. We have rented the entire group campground for Friday and Saturday night of the Thunderbunny weekend. There is room for 50 campers so it is a great way to socialize with fellow Thunderbunny runners! Be ready for a primitive camp experience though as there is no flush toilets, electric, or showers; the group camp does have pit toilets, a water spigot, picnic tables and fire rings. The cost is just $5 per tent, so bring the family, just make sure you select this option while registering.

Strouds Run State Park has over 50 individual campsites for rent all within a half mile from the Thunderbunny race start/finish area. Sites are non-electric and there are no showerhouses, but the campground has running water and pit toilets.

*Changes to the 11K from previous iterations*
In 2022 and 2023 we held the 11K distance on Friday evening, and it also represented the Collegiate Running Association Trail Running National Championship for those years. Starting in 2024 and being the case again in 2024 the 11K will not represent the CRA Trail Running National Championship, and the race will be moved back to Saturday morning, and will start one hour after the 50K and 25K start.
Walkers are welcome to register for the Thunderbunny 11K!
Capacity and Waitlist
The capacity for the 50K, 25K, and 11K is 400 total participants - if we reach 400 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 Tuesday before the race.
Participant Swag and Other Perks

Finishers Award: Finishers of the 25K and 50K will receive a finishers award at the finish line!

Course Description
The Thunderbunny Trail Race courses offer some of the best singletrack trails in Ohio, and runners will be treated with beautiful springtime foliage, full of flowers and lush greenery along the entire course! The 50K course gives everything Strouds Run and Athens has to offer in one go-around, and the 25K+ and 11K courses provide a shortened preview of the best Athens trails! All three distances start with a one mile road section to let the field space out before entering the namesake Thunderbunny Trail. After completing the Thunderbunny and Hollow Point trails the 11K runners will be finished, and the two longer distances continue to make a loop around Dow Lake on the Sundown and Hickory trails. It's not until runners reach mile 15.8 miles that the 50K and 25K split; 25K runners will have just one and a half more miles to the finish, and the 50K route begins the "back half" of the course. The three hardest climbs of the course come in the second half of the 50K - up Finger Rock, up Hope Drive, and then up Athens trail from Sells Park. After the three hardest climbs, 50K runners will still need to complete the Thunderbunny and Hollow Point trails before heading to the finish line.
Enter the 50K to experience a challenging variety of steep long hills on the back half along with the gentler rolling hills in the first half, while running through the best scenery in Athens County! If you're looking for a more gentle experience at Thunderbunny you have the 25K+ and 11K distances that traverses the best singletrack in the park!

Cutoff Details
*Please note that the cutoff times are when aid stations will pull you from the course, or, "cut you off" from the course, and is slower than 9 hour pace. We give you some wiggle room early in the race with regard to the cutoff pace in case you run the second half of the race faster. Please respect the organizers decision of cutoff times and understand these times when entering Thunderbunny. If you arrive at an aid station after the cutoff times you will be told to stop the race, and will be transported back to the finish line.
**For 25K runners, pay special attention to the "Dow Lake Dam" cutoff time, as that is the one true hard cutoff for the 25K course. This time coincides with the 50K cutoff at this location. After the Dow Lake Dam, 25K runners will have a plenty of time to make the Gillette Junction cutoff time, and this is due to that aid station remaining open for the duration of the 50K race.
We do not have a hard cutoff for the 11K course; with the race starting at 9:00AM on Saturday morning you will have plenty of time to finish the 11K course no matter what level you are at or what speed you plan on going. It is great for hikers! 3 hours for the 11K is 24 minute pace per mile, and 30 minute per mile pace for 11K is under 3:30 - this will give most people the ability to finish before 12:30PM.

*The Collegiate Trail Running National Championship was represented at the Thunderbunny 11K in 2019 and 2022-2023. It was run together with the "general field of runners" so we've separated the two course records from "open" and "collegiate."
*Note that the 11K was formerly labeled a 12K in distance.
