You can register online until 9/20/23 at noon time.…unless we close out before then. If there is space available, you can register in person on race weekend.
We have processed thousands of registrations and never had a security breach or lost any information. We take your privacy seriously, so rest assured, you can register safely.
Yes. However, due to the lead time to order our runner shirts, you can only make a switch until 9/1/23 and there is a $20 charge to make that change. There is no refund for the balance of the difference in the price to go from Full to Half, but you will need to pay the increased charge to move from the Half to the Full.

There are NO refunds. We will accept requests for an injury deferment until the end of the day on 9/16/23.
Yes. You must be 16 years old on race day to run the full marathon. You must be 14 years old on race day to run the half marathon. There will be no exceptions considered.
Yes. The standard time requirement is 7hrs 30 minutes. That is a 17:11 minute per mile pace. All course support ends at 2:30 pm to respect the time and energy required from our volunteers and municipal and emergency resources. If you are not confident you can complete the full marathon in that time frame, please register for the half marathon.
Every on-line registered runner will receive a Clarence DeMar Marathon shirt. (Plus an appropriately gaudy finisher’s medal when you cross the finish line!) Men’s and women’s shirts are cut differently. BUT… If you want to guarantee that you’ll get a shirt in your requested shirt size, register early and on-line.
We do our best to give each runner their size, but to get the really cool shirts we all love, we have to order pretty far in advance. If you register early, then we can make a more accurate order. If for some reason we run out of shirts in your size, we will order one and mail it to you.
If the shirt your ordered does not fit, you might be able to switch it after you finish on Sunday after your race.
You are only guaranteed a shirt if you register on-line. Race weekend registrations cannot be guaranteed a shirt.
Yes. The deadline is 9/15/23. You will need to access your personal registration confirmation page to make changes to your registration. Please use the link in your RunReg confirmation email. Please note, there is a $20 fee to be paid by the new runner at the time of registration. Managing transfers is quite a lot of extra work for our registration host and for our registration team.
Runners can check in and pick up their bibs and runner packets according to the following schedule.
Friday, September 22, 2023
Ted’s Shoe & Sport
115 Main Street, Keene NH
Saturday, September 23, 2023
Keene State College
RACE DAY: Sunday, September 24, 2023
Keene State College
Full Marathoners: If picking up your bib and packet on Race Day, do so at Keene State College and then board the shuttle bus to the start in Gilsum.
If you are having family or friends drop you off in Gilsum, pick up your bib and packet at Keene State College first.
Half Marathoners: If picking up your bib and packet on Race Day, do so at Keene State College and then board the shuttle bus to the start in Gilsum.
We encourage runners to make it to any of the 3 times scheduled for runner check in, but if you are not able to make it, you can have someone else pick up your bib and packet if they have something in writing from you giving them that permission.
The Clarence DeMar Marathon course winds through exquisite New England scenery in the early stages of fall foliage season. You also get to run through a classic small New Hampshire town replete with history. All DeMar runners enjoy a world-class running experience, along with the support and encouragement of 300+ volunteers.
Yes! Full - USATF Certificate NH15014TY. Half – USATF Certificate NH14025TY
Absolutely. In fact, that’s what brings many of our runners to DeMar. The date of the Clarence DeMar Marathon is usually after the next Boston Marathon registration has closed. However, a Clarence DeMar BQ will also qualify you for the following year’s Boston Marathon. A 2023 DeMar BQ gives you the opportunity to register for the 2025 Boston Marathon. In 2022, 30% of all DeMar finishers achieved their BQ. Come get yours and ring our DeMar BQ Bell!
In both the Full Marathon and the Half Marathon: First place male and first place female. Both these champions will have an automatic entry to the 2020 DeMar to defend their titles.
1st and 2nd place in each age category:
We also recognize the top 3 male and female Cheshire County finishers.
Men – Neil Wood – 1983 – 2:17:05
Women – Cathy O’Brien – 1995 – 2:33:56
We strongly discourage walkers, especially for the Full Marathon! There is a 7 ½ hour time limit for the full which begins at 7:00 am sharp and ends at 2:30 pm. At that time, all course support is pulled from the course. We rely on the generosity, energy, and enthusiasm from hundreds of community volunteers, not to mention municipal and medical resources. It is not fair to ask them to maintain that level of support for any longer than we already do. If you are not able to maintain an average pace of 17 minutes per mile, please register for the DeMar Half Marathon.
Runners may park in any of the Keene State College Lots. See the Parking Map and Parking Details. Please do not park in a lot reserved for residential students, a fire lane, a lawn, or a handicapped space without a permit as you will be fined and/or towed.
If you took the bus from KSC to your start, your car will be waiting for you at the college when you finish. If you parked at the Surry Mtn Lake parking lot, there are busses to return you there. The gates to the Surry Mtn Lake recreation area will be closed at 2:00 pm so it is critical you are out of there before then.
Two buses will return Half Marathon runners to the Surry Mtn Lake. Buses will leave from the Maddison St parking lot at 12 p.m. and 1 p.m.
There are no buses returning to the Gilsum start line.
The Half Marathon begins at the Surry Mtn Lake in Surry, NH. (See the course map.) NOT the Surry Mountain Dam! Drive past the Surry Dam Rd and the entrance to Surry Mountain Lake is less than a mile past that on your right. You may park there, be dropped off there by family and friends, or you may take the shuttle buses from the Keene State College Spaulding parking lot.
The full starts on Main St in Gilsum NH. Runners are brought to the Gilsum Elementary School where they will have a short walk to Main St. The Gilsum Elementary School is located past Main St on Rt 10 North in Gilsum.
Yes. Note that there are two bus shuttles returning to the Surry Mtn Lake from the Keene State College Spaulding lot, the first at 12 p.m. and the last at 1 p.m. There are no bus shuttles returning to the Gilsum start.
All buses leave from the Spaulding parking lot at Keene State College. (TK-See Parking Map.) Parking for shuttles to the starting area in Gilsum and Surry will be in any of the Keene State College Lots. Please do not park in a lot reserved for residential students, a fire lane, a lawn, or a handicapped space without a permit as you will be fined and/or possibly towed.
Make sure you are on the right bus. They will be labeled.
Full Marathon runners to Gilsum start
Buses run from 5:15-5:45 a.m. Buses leave when full or nearly full.

You will get to experience early foliage here in Southwest New Hampshire. The weather is generally between 30F and 60F, but it can fluctuate beyond that. Humidity is generally low, but again, in New England, it is hard to predict. As the locals say, it’s spring in the morning, summer in the afternoon, and fall at night! Please check the weather starting a week before the race to make sure you dress appropriately. Please see our severe weather policy.
Dogs—No. We love dogs, cats, geckos, hamsters, goats and any other animal that could be considered a pet, HOWEVER, for their safety, please leave them at home. This includes wookies. You may bring husbands as long as you leash them (they have a tendency to wander into traffic).
Strollers—No. Spectators are welcome to have strollers.
Headphones—Discouraged. The USA Track & Field sanctioning body strongly recommends that, for their safety, runners not use headphones or earbuds. It is not prohibited at the Clarence DeMar Marathon and DeMar Half Marathon, but discouraged for the safety of our runners.
There are 15 aid stations on the full course and 10 for the half. Each station has Gatorade and water. They DO NOT include any other supplements. Download Full and Half Marathon Map
Yes there are. There are plenty at the start of each race, and then about every 5-6 miles along the course. Signs will give you a heads up on when one is coming up. Download Full and Half Marathon Map
Some good “Race Etiquette” to be aware of: Answer: We are very proud anytime someone chooses DeMar for their first full or half marathon. We hope to share some general race etiquette to be aware of to enhance your experience:
- Pay for your spot: Running in a race you haven't entered, also called "banditing”, is not fair to race organizers, volunteers, and especially the people who have paid to participate. It's also unsafe, since race organizers plan their course amenities, such as water and sports drinks, and medical assistance based on the number of people who have signed up for the race. And overcrowded race conditions can lead to falls and other problems. Don't do it.
- Don’t run with someone else’s bib number: Race organizers must work very closely with the local Emergency Management Agency and supply an entrant database to all area EMS departments. This database includes all runners first and last names by bib number, along with the corresponding emergency contact information for each participant. If a runner wearing your bib has a medical issue, we won’t be able to help them as effectively if we don’t know them. If you run using someone else’s bib, we don’t know you, so you’re at risk as well. You get the idea. Run only with your own race number—period. If we find you doing otherwise, you and anyone else involved risk being suspended from future DeMar events.
- Line up properly: The Clarence DeMar Marathon and DeMar Half Marathon is a small event and since there are no starting corrals, runners must 'self-seed' themselves at the starting line. Nothing is more annoying to a runner at the start of a race than having to weave around slower runners after the gun goes off. Faster runners should line up at the front of the starting line, slower runners and walkers at the back. If you are unsure if you are lined up in the right place, ask some of your fellow nearby competitors their anticipated pace, and if it's faster than yours, move further back. The full and half marathon are chip-timed, so the time it takes you to reach the starting line won't count in your final net time.
- Don't jingle: Don't carry loose change or a set of keys in your pocket. Although it may not bother you, the constant jingling can be really annoying to those who are running near you.
- Don't block the running path: If you're running with a group, don't run more than two abreast (i.e., 2 runners side-by-side), so others can pass you.
- Show volunteers appreciation: Please say "Thank You!" to race volunteers who hand you water, put your medal around your neck, or otherwise help you. They're volunteering their time and the race would not be successful without them.
- Thank supporters, too: Acknowledge race spectators who cheer for you as you pass them. If you're too tired to say "thanks," show them a smile, wave, or give them a thumbs up. It will make them feel good and encourage them to keep rooting for others.
- Use caution at fluid stations: Water stations can get a bit chaotic and crowded. Use caution when running into a water stop and make sure you're not cutting off other runners or spilling water on them. If you're going to stop or slow down to walk through the water stop, make sure there's not a runner behind you.
- Keep moving at the finish: Don't immediately stop at the finish line or in the chute. There will be runners coming in right behind you, so keep going until its safe to come to a stop.
- Don't be a glutton: Don't take more than your fair share of food and drinks at the finish line. The back of the pack runners will appreciate it when there are still enough goodies for them at the end.
