25K COURSE DETAILS AND MAPS
25K Course Description
The 25K course is so awesome that you'll get treated to 3K of free running, as the course comes out to 28K in total! We believe in a great course, not comprimising that just to get a certain distance. The 25K mark will be clearly marked so you can see your time. Runners in the 25K will start along with the 50K runners at the beach parking lot and run the same course with them before turning off to complete the final mile. The split-off for the 25K and 50K runners is at the Gillette Junction Aid station around mile 16.5. Do Not go the wrong way here, or you will be running the 50K! This course features all the great trails of the 50K but just half the distance! You will start off and run a mile before entering the namesake Thunderbunny Trail and be on the rolling singletrack trails of Hollow Point and Sundown for next 12 miles until you reach the Dow Lake Dam. After grabbing some fuel at the aid station, you'll complete the loop around the lake by running the more flat Hickory Trail before reaching Gillette Junction where you'll split off to go to the finish line. All in all this mostly singletrack course has a manageable 1755 feet of elevation gain, good for the first time trail runner and veteran alike!

25K Aid Station Chart
The 25K cutoff times will coincide with the 50K course cutoff times. 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.
