Go long (25K), longer (50K), or longest (50M) in this internationally recognized ultramarathon at the Finger Lakes National Forest in Hector, NY.
ABOUT
Saturday, July 5, 2025
Start times:
50 Mile and 50K at 6:30 AM
25K at 8:00 AM
The Finger Lakes 50s consist of 50-mile, 50K, and 25K trail races in the Finger Lakes National Forest in Hector, NY. Each distance is part of the Finger Lakes Runners Club Trail Circuit, and results are included in our annual Pebblehead/Stonehead/Boulderhead rankings.
All three races will use the same loop course, starting and finishing at the Potomac Group Campground. The course is a 16.5-mile loop covering singletrack trail, grassy pastures complete with grazing cows and cow pies, and dirt roads. Run it once, twice, or thrice for your respective distance. The 50K and 50-mile races start at 6:30 AM and the 25K race starts at 8:00. Runners will encounter 1,300 feet of elevation gain per loop and five aid stations on each loop. Note that the 25K and 50K run “long” at 16.5 and 33 miles, respectively. But hey, that’s more mileage per dollar! 50-milers do an extra half-mile loop at the end to get their full distance.
If you’ve never run a trail race before, check out our First-Timers FAQs for Trail Races. (And you might want to try a shorter one first!)
LOCATION and PARKING
The race starts and finishes at race headquarters—which doubles as the Living Room aid station—at the Potomac Group Campground in the Finger Lakes National Forest. The campground is located just off Potomac Road, about a half-mile north of the intersection between Picnic Area Road and Potomac Road.
Parking:
Parking is available on Potomac Road only and is limited to the west side of the road. (Please abide by the “No Parking” signs on the road’s east side.) In addition, parking will not be permitted in the entrance or driveway to the Potomac Group Campground parking lot, nor the area designated for the “Baby Loop” on the 50-mile course.
Any vehicles parked in a “No Parking” zone will be towed at the owner’s expense… and after running all day, it wouldn’t be too fun to find your vehicle gone!
Parking in prohibited areas violates the terms of our permit with the Finger Lakes National Forest. Emergency vehicles, race vehicles, and general public use vehicles must be able to use the road while the race is in progress.
Due to the number of cars that will be parked along the road, you may have to park some distance from the race registration area. Please make sure that you arrive early on race day to account for this.

If you do want a pacer, they must register by filling out the online Pacer Registration and Waiver Form, and submitting to FL50s@fingerlakesrunners.org. This ensures we and WSAR keep track of who is out on the course. There is no fee for pacers. However, if pacers would like to purchase any meals, and submit payment via Venmo or Square (contact RDs). Meals are $12 apiece.
The form can be completed prior to race day if no extra meals are to be purchased (or by June 1 if purchasing a meal), or a paper form can be completed at the time of packet pick-up at the race site.
Pacer Rules

- Pacers must stay with the person they’re pacing at all times.
- Pacers must be at least 18 years old.
- Pacers cannot mule for their runner—that is, carry ANYTHING (fuel, clothing, etc.) for the runner they are pacing.
- For liability purposes, the Pacer Registration and Waiver Form must be completed by anyone wishing to pace.
- All pacers will be provided with a pacer bib which they must wear at all times on the front of their body while out on the course with their racer.

*Course distances are approximate and biased on GPS system.
Course Elevation:
This elevation chart will provide a close representation of the FL50s course with an elevation gain of approximately 1,300 feet per loop.
All three races will use the same loop course, starting and finishing at the Potomac Group Campsite. As noted above, the course is a 16.5-mile loop covering singletrack trail (85%), grassy pastures (5%) complete with grazing cows and cow pies, and dirt roads (10%). 25K runners complete a single loop, 50K runners run two loops, and 50-milers complete three loops plus a half-mile “baby loop” to give them a nice round 50 for the day. Runners will encounter five aid stations on the course including the finish area. (There are five individual aid stations, but runners will hit the South Beach aid station twice, making it six.)
Aid Stations: The Morgue is back! Plus, you can get water, electrolyte mix, snacks and help from volunteers at South Beach Back Aid Station. That being said, please plan on carrying water and food with you.
The course will be marked with signs consisting of blue arrows over a white background, and pink flagging. Follow these markings and no others. There are a ton of interconnected trails and dirt roads throughout the forest, and it can be easy to get lost if you aren’t paying attention. If you come to a red “wrong way” sign, you’ve gone the wrong direction. The Finger Lakes National Forest has orange, white, and blue blazes on the trees—ignore these blazes, and only follow the blue arrow signs and the pink flagging. The arrow signs will only be posted where you need to make a turn—if you don’t see an arrow, don’t turn onto another trail. If you see pink flagging, follow it!
You’ll encounter a number of boardwalks throughout the course. These boardwalks have a nasty reputation for being very slippery, even if it hasn’t rained, and broken in places—please watch your step. They also act like see-saws and trampolines.
There is a short section where runners will be moving in both directions. About a mile up the trail after leaving Mark Smith Road, and again as you approach the South Beach Front Aid Station (AS #2). Please stay to the right side of the trail to allow for two-way traffic without risk of collision. This section will be well-marked to eliminate any confusion.
For a complete description of the course: See the detailed course description.
RACE RULES
- Race Day Check-in: You MUST check-in prior to your starting time before race-day morning, even if you picked up your packet the day before. For your safety, we must have an accurate number of runners on the course.
- Cut-off Times:
- 25K: There is no cut-off time; runners will be completing one loop (16.5 miles).
- 50K: Need to complete Loop 1 by 12:00 noon (5 hours, 30 minutes elapsed)
- 50-milers: Need to complete Loop 2 and start Loop 3 by 2:15 PM (7 hours, 45 minutes elapsed).
- 50-milers: Also need to reach and leave the Library aid station on the third loop (roughly 10 miles into the loop and 43 miles into the race) by 5:00 PM (10 hours and 30 minutes elapsed) to continue.
- If you were planning on doing the 50-miler and didn’t make the cut-off to start Loop 3, your time will be counted as a 50K finish, but you won’t be eligible for awards.
- If you finish Loop 2 and have met the cut-off time, but are unsure about continuing and you linger at the aid station, you must report to the finish line area if you decide to continue on or if you decide to stop. If you stop you can go through the finish line again for a 50K finish. (See bullet above.)
- If you start Loop 3 but miss the cut-off time at the Library (5:00 PM), it’s a DNF.
- Headphones/Earbuds: Wearing headphones is prohibited—the course can be crowded and people need to be able to communicate and hear. Wearing headphones during road sections that are open to traffic could result in disqualification. This is both for your own safety and that of others. It is important that you remain aware of your surroundings.
- ABSOLUTELY NO LITTERING! Carry-in, carry-out, or throw it in a trash bag at an aid station. Those found littering will be disqualified!
- NO BANDITS: Anyone found running as a non-registered runner or pacing for a 50-mile runner will be banned from all future Finger Lakes Runners Club events.
- Dropping From Race: If you decide to drop out while you are out on the course, you MUST inform a Wilderness Search and Rescue volunteer or race official that you are dropping out. Once you have dropped, you may not change your mind and continue in the race. When you finish the race, you must make sure that race officials are informed. If you leave the race without informing the race officials, we will think that you are still out on the course and we will be searching for you! We do not want to be out looking all night for someone who is not out on the course.
- Bib Numbers: You must wear your number in the front at all times and your number must be visible to the race volunteers. DO NOT FOLD OR ALTER YOUR RACE NUMBER IN ANY WAY. A DISPOSABLE TIMING DEVICE IS ON THE BACK OF THE BIB, AND FOLDING YOUR BIB MAY CAUSE THE DEVICE TO MALFUNCTION AND FAIL TO RECORD YOUR TIME. It is your responsibility to make sure that your number has been recorded when you go through an area where numbers are being taken. If it is found that your number was not taken at one of these locations, it will be assumed that you did not go through that area, and you will not be counted in the finishing results.
- Changing Race Distances: Runners registered for the 25K race may not change race distances. 50-mile and 50K runners may switch distances as long as they’ve met the cut-offs (see above) but are eligible for awards only in the distance for which they registered. If you have registered for either the 50K or 50-mile, and you decide prior to the start to switch distances, please inform registration – this allows registration to issue you the correct bib for the distance registered. If you have registered for the 50K or 50-mile races and you decide to switch after your start, please make your decision before you reach the finish line area of your second loop to know which mat you will be crossing—the FINISH mat or the LAP mat. 50-milers who cross the LAP mat after the 50K distance and then decide not to go on for the 50 miles will then have to cross the FINISH mat to record their finish time for the 50K. However, switching after your start disqualifies you from awards.
- Continuing After Each Loop: Each time you come through the lap area and intend to go on for the next lap, you must do this within a reasonable period of time after going through the aid station. If you meet the cut-off time, but linger at the aid station and the cut-off time lapses, you will not be permitted to continue because you didn’t start the next loop BEFORE the cut-off time.
- Disqualification: Anyone who does not comply with these rules risks disqualification as well as being banned from any future Finger Lakes 50s event.
WARNINGS
- Temperature During Race: If the temperature exceeds 80° F, as it often does on race day, it’s wise to carry enough water to last for at least an hour or two.
- Don’t Let The Cows Out! You will be running through three pastures that have cows (and possibly a bull.) These animals are naturally curious and sometimes like to follow you. You MUST close the gates behind you! DON’T LET THE COWS OUT, and do not antagonize the animals. We cannot and will not be accountable for animal actions or injuries resulting from irresponsible behavior. Please do not wish to put future editions of this race in jeopardy!
- Horses and People on the Trails: The trails are open to the public. You may encounter other people, forest rangers, and/or horseback riders. If you come upon a horse, please announce yourself to make sure that the horse and rider know that you are approaching and walk past the horse to avoid startling the animal. Please be courteous to any non-racing individuals enjoying the trails. They have just as much right to be out there as you do.
- Your Health and Well-being: You are responsible for your own health and well-being—please know your abilities and take care of yourself. There will be Wilderness Search and Rescue personnel around the course to assist you in the event of an emergency—let’s do our best to ensure they are bored. If it appears that you are becoming physically or mentally impaired during the race, race officials and/or volunteers have the right to pull you from the race. If you are asked to stop, you must comply.
- Dogs at the Race (spectators/crew): It’s preferred to not have dogs at the race—it gets crowded, and in past years we’ve had dogs get in fights and runners get tripped by dogs. If you do bring your dog, dogs are not permitted near any of the aid stations. If you go to an aid station with your dog, you must stay clear at a distance from the actual aid station so your dog doesn’t get in the way of runners and volunteers. Dogs must stay on a leash at all times with a responsible adult. Dogs are not permitted to run with any racer or pacer. For more info, go to the FAQ page (second to the last question).
- Assisting Runners: Family/friends who drive around the course to see their runners MUST be aware that runners will be crossing and/or running on portions of various forest roads. Crew members—please drive slowly and cautiously. If you are at an aid station to assist a runner, you need to stay clear of the actual aid station so you don’t get in the way of volunteers assisting other runners. We have very capable and helpful volunteers at our stations. Extra people stepping in creates confusion for the volunteers who are trying to help and track the registered runners.
- No Fireworks: Yeah, it’s close to the Fourth of July, but fireworks are prohibited per National Forest permit regulations. As is gambling. So leave that slot machine at home!
