Post-Race Message from the Race Director
Well, another Seneca Creek Greenway Trail Event is in the books! It was a perfect day for a run along some beautiful (and at times challenging) Maryland trails. This year was a largest field yet and the first year we offered a 2-person relay option.

From what we’ve heard from the runners, the overwhelming majority of you totally enjoyed the day and were happy with all the details we put into the day for you. From the supportive volunteers, to the great aid stations to the wonderful finish line fire, food, and brew!

Hoping to see you all again next year on March 3, 2018!

2017 testimonials:

Kathy Bush (50k finisher) “Thank you so much for such a wonderful race! It was our first 50K and we loved it! The volunteers and race director made our day! We are thrilled to call ourselves ultra runners!”

Manor Hazbon (50k finisher) Thanks sooo much for the great event yesterday. It was my first ultra, and a memorable one.

The event was perfectly well organized, great food at the aid stations and at the end. Beer was awesome and the soups, hot dogs and everything else was perfect. Thanks a lot!

Camilo Lopez (50k finisher) “Yesterday was my first time doing your race (and first 50k). I was amazed by how well organized the event was. Easy to get, simple registration. Beautiful course. No BS. How friendly and helpful all of the volunteers were. Well stocked aid stations. The people running were also courteous and supportive (and strong, guess that’s the people who sign up for a race in early march). Food afterwards was plenty and tasty.

I wanted to congratulate you and Paul and all the staff on an excellent well organized event. I wish I could give you feedback in how to make it better but I think it is perfect as it is.

Matthew Prineas (50k finisher) “Thank you –and thanks to all the volunteers — for an absolutely wonderful experience yesterday.   

Although I have been running & training for ultras on these trails for years, for some reason I never got around to signing on for this springtime race.  I’m so glad I did.   What’s really cool is how you are acting as ambassadors for trail running and for ultras–and introducing folks a little bit to the ethos of our community (“no whining” for example).

If my schedule doesn’t allow me to race next year, I hope you’ll put me on your list of volunteers.   

Jane Heinrichs (relay finisher) “The relay was fun!  I hope you have it next year as well!  Brad and I came in 4th!  The first three teams were way faster!!”

Race Location:
Seneca Creek State Park
11950 Clopper Road
Gaithersburg, MD, 20878


From I-270, exit at Clopper Rd W (MD 117). Proceed about 2 miles to the Seneca Creek State Park entrance on your left. You will be directed to the parking area after you pass the gatehouse. Parking is limited so please make efforts to carpool.

Course: This is a loop course beginning and ending at Seneca Creek State Park with ALL participants running together until the decision point. Relay participants will hand off their race bib AND chip approximately mid-way to their team mate. Only runners with bibs at the end will be timed.

Start Time: All race options will start promptly at 7am.

Cut offs: The courses will close after 8.5 hours allowing plenty of time for all participants for whatever “extras” the course holds on race day. The finish line will close at 3:30pm.

Registration: We will have online registration only. Please note that registration opens Monday, December 5, 2016 and will close when we reach our race cap of 400 runners or by Friday, March 3, 2017 whichever comes first. PLEASE NOTE: The marathon relay will be capped at 50 teams (100 runners total) and combined participants for 2 other individual events will be capped at 300.

Cost: Individual Marathon or 50k:  MCRRC members $25.   Non-members $35
* All 50k Relay Teams:  $50
* Must register and pay as a team

Race Distances
All race distances are APPROXIMATE, as are most trail races. With that in mind, the following are the approximate distances for our events. 50k=31.8m; Marathon=27.8m; 50k Relay 1st leg=14m, 2nd leg=18m.

Packet Pick-up: Packet pick-up will be race day morning at Seneca Creek Park from 6-6:45am.

Refunds and Bib Exchanges: We understand things can happen that prevent us from running goal races but in a low-key race like ours it’s just not practical to process refunds or do bib exchanges. If you decide to withdraw from the race please email the race director and your entry fee will be donated to the Maryland State Park system for continuing improvements to our trail system. 

Race switches: Runners for either the marathon or the 50k will choose their race distance when they register but anyone can switch on race day, if they reach the decision point by 2:25pm (it will be clearly marked and attended). PLEASE INFORM VOLUNTEER at this juncture if you are switching distances. This option is not available for the relay teams.

Weather: Weather around the DC region in early March is unpredictable. We have had warm, snow-free years and years (like 2015) where we’ve gotten 1-2’ of snow the day before. Historically there’s been light layer of snow at the start and temps that stay below 50 degrees through the day. Please check the forecast before you come so you are well prepared.

Safety: Remember when approaching road crossings, CARS are the ones that have the right-of-way! All runners are expected to stop at road crossings. Volunteers will be there to help direct you across roads but will not stop cars.

Timing: We will use chip timing. The chips will be taped to the back of your bib when you get it. You will need to remove the chip and fasten it to the laces of one of your shoes with the cable ties we include in each runner bag in order to be timed. Relay participants will have 1 bib and 1 chip that will be exchanged at the hand-off point. If the second runner doesn’t not have a bib or chip at the finish they will not be scored.

DNF’s: If for any reason you find yourself unable to finish your race, please make your way to the nearest aid station and let the volunteers know so we can get a ride for you back to the park.

Because we want to make sure everyone is accounted for, it’s is important that you let someone know you can’t continue AND drop your chip with an aid station volunteer. We don’t want to be scouring the woods for someone who made their own way home and didn’t let anyone know

Drop Bags: We will allow 1 bag drop if anyone needs a change of shoes or particular foods/drink. Put your items in an easily recognizable bag of your choosing CLEARLY marked with your name (easily identifiable makes for easily retrieved). Bags will be at the 15m point (Berryville Aid Station) in a clearly visible drop area. You will be responsible to find your own bag….and remember the bag drop is At YOUR OWN RISK.

Water bottles: Every runner is expected to carry their own water bottle (and personal choice of drink powder). Aid Stations will have water and lemon Gatorade probably every five to seven miles. Be prepared to fill your own bottles with your choice of water or Gatorade.

Other Details:

Carpooling: The race will start and finish in the park and we do have limited car space. If you are local, please consider carpooling.

RELAY TEAMS Carpooling: Relay teams will provide their own transportation to the exchange point along Seneca Rd by the Greenway Trail entrance where the handoff will occur. Please check course map on the website in advance. The 2nd leg relay runner should drive to the exchange point close to the time they anticipate their team mate arriving. The exchange point will be clearly marked and once the handoff of chip & bibs are made, the 1st leg participant will drive back to the finish using the same car. Please park your car far enough on the shoulder to allow regular flow of traffic on this side street!
