In the first race of the series, the Macricostas 10K runners will get to experience the climb up to the summit at Waramaug’s Rock, an outcropping with an amazing viewpoint of Lake Waramaug below. The 10K course is a challenging one, with mostly singletrack trails, two steep climbs, and some amazing technical downhills! It will certainly be a test of your endurance and concentration. The shorter 5K includes one steep climb plus the rocky technical downhill of the Meeker Trail. Those who love a short, but challenging hike can also find this a great option!

T-shirts will be offered to all pre-registered runners in the 10K.

Refund Policy: There will no refunds and/or no transfers of your registration or bib to any other person. Entry fees collected are used to develop and produce the event, starting well in advance of the race date--including course preparation, race supplies, permits, and administration.

Hikers/walkers are welcome to do the 5K. Runners wishing to drop down from the 10K race to 5K may do so before race day by emailing the race director.

Course Description

10K: The first race in the Steep Rock Trail Series, the Macricostas 10K starts at the far northeast corner of the big grassy field. A clockwise quick trip around the southern and western side of the field and then runners are onto to singletrack trail before taking the left turn up the steeper section of the Meeker trail to Waramaug’s Rock, a beautiful outcropping above the tree line overlooking Lake Waramaug below. Take a moment to sink it all in. It’s one of the best views of the entire day! A quick, but partially technical trail down to the June Rd. aid station and you are travelling back towards the huge rock again. Moving back off the pinnacle, runners will go clockwise down the Meeker Trail, a longer, winding, technical single track back to the grassy field and to the opening to the grassy field. Runners will then run clockwise to return to the finish line at the southeast corner of the field. This is not an easy course, but is runnable in most sections and will certainly challenge you!

5K: The 5K course starts just to the west of the start line and then travels clockwise, with a slight variation (from the 10K course) to the entrance of the Meeker Trail singletrack section. Runners will then make the left turn to go up the steeper section of trail. Upon getting to the lookout point (with an amazing view of the field below), runners will continue and then within .2 miles go straight to connect with the longer, more technical section of the Meeker Trail, travelling clockwise back down to the field. A quick left hand turn onto the field and a it’s a about a half mile to the finish line!

Aid Stations

Will we have water and/or electrolyte drink at the aid station for the Macricostas 10K. Steep Endurance events are "cupless" races. Runners are required to carry their own hydration bottle, pack, or cup. This policy is put into effect in an effort to reduce the amount of waste and adopt a sustainable “green” practice for the series and the sport of trail running.

June Road (2.95 miles): This aid station will be located at the trailhead on June Rd. at just before the 3 mile mark.

Waramaug’s Rock (TBD): There may be a second aid station located at the top of the climb to Waramaug’s Rock

Runner Rules

These rules are meant to make your experience during any Steep Rock Trail Series event a positive one. Most of these are common sense type policies that you will see at any trail or ultra race.

  • Absolutely No Littering! The vast majority of each course is on Steep Rock Association preserve land. Please respect that we are using their 3 amazing and beautiful trail systems for our races. Failure to do so could jeopardize the future of the series.
  • Race entries/bib numbers are not transferrable--hence NO unofficial runners
  • Following the marked course is mandatory. Please do not cut the course, cut any switchbacks, etc. Any runner caught doing so will be disqualified. In addition, if you get lost on the trail/road you must return to the point at which you lost the trail. The course will be well marked with ribbons and other necessary course markings.
  • Though the course will be VERY well marked, runners are ultimately responsible for knowing the course and carrying course maps if necessary.
  • Please respect others that are on the trail. Most of the trails on the course are open to the public and some are fairly well travelled (especially those in the main Steep Rock Preserve). Please announce your intentions to pass if you are coming upon a hiker or another runner.
  • If you must use the bathroom, please try to do so very discreetly a good distance off the trail before returning to the race.
  • If at anytime you intend to drop out of the race, please do so at an aid station/checkpoint by notifying the aid station captain. Surrendering your bib to the aid station captain will serve as notice of withdrawal/DNF for the race. Failure to follow these policies means somebody has to come looking for you. While this isn’t a marathon/ultra race, it is a trail race with some remote sections of trail, where we will be forced to have someone come looking for you and in some cases, local authorities (at your cost).
  • Smoking is not permitted on any of the trails or at any checkpoint by runners (probably shouldn’t be doing during a trail race anyway). Alcoholic beverages are also not permitted in any sections of the Steep Rock Preserves.
  • The use of personal music devices is strongly discouraged at this race. To enjoy all that our race has to offer and for the safety of all participants, the Steep Rock Trail Series encourages a headphone-free environment during the running of the race. We believe your race experience and those around you will be greatly enhanced by leaving the headphones at home or in the car. Running headphone-free allows opportunities to develop camaraderie with your fellow runners and to enjoy everything the race has to offer. Plus, volunteers and spectators will be on course cheering you on and providing directions to help get you to the finish line. Runner safety will be a top priority for our events.
  • SMILE and enjoy the race! You are lucky to be enjoying these beautiful trails!


Each race in the Steep Rock Trail Series will offer awards in the following age groups for both men and women:
Overall, 19 and under, 20-29, 30-39, 40-49, 50-59, 60 and up.

Special “Steep Rock Trail Series” awards will be given for series winners in the following categories: Overall Male/Female (1st, 2nd, and 3rd), Masters Male/Female (1st).

Medals will also be given to any participant who signs up for IN ADVANCE and RUNS in each of the three Steep Rock Trail Series events.

Post Race Celebration

You’ve just finished a super challenging course! Enjoy your accomplishment, sit back, relax, and don’t forget to cheer on all the runners coming in behind you! We will have the usual spread including bagels, bananas, pizza, non-alcoholic hydration options. **There is no alcohol permitted in any of the Steep Rock Association Preserves.
