The MARS Maryland 5 Star at Fair Hill represents the pinnacle of equestrian sport, standing as one of only two CCI5*-L (five-star) eventing competitions in the United States and one of only seven held globally. This annual event transforms the Fair Hill Special Event Zone in Elkton, Maryland, into a world-class stage where the finest horse-and-rider combinations test the limits of stamina, precision, and partnership. Named for its titular sponsor, Mars, Incorporated, the event has quickly established itself as a crown jewel of the international eventing calendar since its inception in 2021.

What is the MARS Maryland 5 Star at Fair Hill?

To understand the prestige of the Maryland 5 Star, one must understand the sport of eventing. Often described as an equestrian triathlon, eventing combines three distinct disciplines—Dressage, Cross-Country, and Show Jumping—into a single competition. The "5 Star" (CCI5*-L) designation is the highest level of difficulty assigned by the Fédération Équestre Internationale (FEI).

Athletes competing here are not just riding; they are navigating one of the most grueling physical and mental challenges in sports. The Maryland event is unique for its location in the rolling hills of Cecil County, a landscape famous for its historical connection to foxhunting and thoroughbred racing. The venue at Fair Hill was specifically upgraded to meet five-star standards, featuring a world-class turf arena and a sprawling cross-country course that makes use of the natural, undulating terrain.

The Three Phases of the Five-Star Challenge

A five-star eventing competition is a test of versatility. A horse must be calm and obedient for dressage on Thursday or Friday, brave and fit for cross-country on Saturday, and agile and careful for show jumping on Sunday.

Phase One: The Precision of Dressage

The competition begins with dressage, held in the main arena. In this phase, horse and rider perform a series of predetermined movements, known as a "test." Judges look for fluidity, balance, and the horse’s responsiveness to the rider’s subtle aids. At the five-star level, the movements are complex, requiring years of training. The goal is to finish with the lowest score possible, as dressage penalties serve as the starting point for the rest of the weekend.

In recent iterations of the Maryland 5 Star, we have seen legendary riders like Boyd Martin deliver polished performances that set the tone for the event. The atmosphere in the stadium can be electric, and a horse’s ability to remain "settled" despite the crowds and cameras is often what separates the leaders from the rest of the field.

Phase Two: The Bravery of Cross-Country

Saturday is the heart of the Maryland 5 Star. The cross-country phase is what defines the event's difficulty. Riders must navigate a course nearly four miles long (approximately 6,270 meters), jumping around 30 numbered obstacles (totaling over 45 jumping efforts) at a speed of 570 meters per minute.

The Maryland course is notorious for its hills. Unlike the flatter tracks found at other international venues, Fair Hill requires a horse with a "big engine"—often a Thoroughbred or a high-blood sport horse—that can gallop uphill at the end of an 11-minute course. The obstacles are solid and unforgiving, including massive timber rails, water complexes, and "skinny" jumps that test steering and honesty.

Phase Three: The Tension of Show Jumping

The final phase takes place on Sunday after a rigorous veterinary inspection to ensure the horses are still fit to compete. Show jumping tests the horse’s ability to jump a course of delicate rails after the exertion of the previous day. One "rail down" adds four penalties to the score, which frequently reshuffles the leaderboard at the last minute. It is a game of millimeters where the pressure is immense, especially when the top five riders are often separated by less than the cost of a single jump.

Deep Dive into the 2025 Cross-Country Course Design

A major talking point of the 2025 MARS Maryland 5 Star was the transition in course leadership. Following the retirement of legendary designer Ian Stark, French designer Pierre le Goupil took the reins. Le Goupil, known for his work at the Paris 2024 Olympics, brought a fresh, technical perspective to the Maryland hills.

The Signature Obstacles of the 2025 Course

The 2025 course was designed to be a "true test of the level," requiring riders to act quickly on their feet. Some of the most discussed features included:

  • The MARS Sustainability Bay (The Crab Water): This is perhaps the most photographed fence on the course. In 2025, it featured a massive angled brush drop into the water, followed by a brush corner and a bank out over a brand-new carved crab. The technicality of the line required horses to stay focused while splashing through the water.
  • The Chesapeake Beasts: Located early in the course (Fence 7), this combination featured keyhole brush corners shaped like owls. These "beasts" tested the horse’s eye and the rider’s ability to maintain a straight line through an intimidating visual.
  • The Yanmar Sunken Road: A maze of fences that allowed riders to choose their own lines. This type of obstacle tests "rider peripheral vision," according to experts, forcing them to commit to a path and stick to it.
  • The Fair Hill Finale: The final jump, a beautifully crafted table, signaled the end of a nearly 4-mile journey.

The optimum time for the 2025 course was set at exactly 11 minutes. Historically, very few pairs make the time at Maryland due to the steep terrain. For example, in previous years, only a single rider like Mia Farley might achieve a "double-clear" (no jumping or time penalties), highlighting the difficulty of the task.

Key Performances and Leaderboard Dynamics

The 2025 event saw a thrilling battle between established veterans and rising stars. International representation was strong, with riders traveling from New Zealand, Great Britain, Switzerland, Australia, and Canada to challenge the American contingent.

The Rise of Thoroughbred Heart

One of the most inspiring themes at the Maryland 5 Star is the success of Thoroughbreds. These horses, many of whom are "off-the-track" (former racers), possess the natural stamina and "grittiness" required for the Fair Hill hills.

In the 2025 cross-country phase, Monica Spencer of New Zealand, riding the Thoroughbred gelding Artist, demonstrated why these horses are the kings of the sport. Delivering one of only four double-clear rounds, Spencer maintained her lead heading into the final day. Other notable Thoroughbred performances included Mia Farley and Phelps, who have become crowd favorites for their consistent ability to "beat the clock" on cross-country day.

The American Veterans

U.S. Olympic veteran Boyd Martin, who won the inaugural Maryland 5 Star in 2021, remained a dominant force in 2025. Competing with multiple horses such as Commando 3 and Luke 140, Martin’s performances in the dressage arena often set a high bar. His ability to produce a polished test under high "atmosphere" is a testament to his experience at the world stage.

Why is the MARS Sponsorship Important?

The "MARS" in the event title refers to Mars, Incorporated, the global confectionery and pet care giant headquartered in Virginia. Their involvement is more than just financial; it reflects a deep commitment to the equestrian community and pet health.

Through the MARS VIPet experience and the MARS Equestrian brand, the sponsor brings a unique flavor to the event. They advocate for a pet-friendly environment, which is evident in the event’s logistics. From providing "Kids’ Corner" activities to sponsoring the highly popular Corgi Cup, Mars has helped turn a niche sporting event into a massive community festival.

The Spectator Experience at Fair Hill

The MARS Maryland 5 Star is designed to be a "family-friendly festival" that goes beyond elite sport. Even for those who aren't horse experts, the weekend offers a variety of attractions:

  • The Fresh Food Fest: Featuring local Maryland delicacies, including world-famous crab cakes and regional favorites.
  • Beer, Wine & Spirits Expo: A chance for adults to sample the best of Mid-Atlantic craft beverages.
  • Shopping: A massive vendor village offers everything from high-end equestrian gear to handmade jewelry and home decor.
  • The Corgi Cup: A fan-favorite event where dozens of Corgis race across the turf, providing a lighthearted break from the high-stakes jumping.
  • Tailgating: On Saturday, the cross-country course is lined with tailgating spots where fans set up elaborate picnics and themed parties to watch the horses gallop by at close range.

How to Prepare for Your Visit to the Maryland 5 Star

If you are planning to attend, here are a few essential tips for a successful experience:

  1. Wear Comfortable Shoes: You will do a lot of walking, especially on Saturday if you want to see different parts of the cross-country course. The terrain is uneven and hilly.
  2. Bring the Dog: Dogs are welcome but must be kept on a leash. The event is very pet-friendly, with water stations and special areas for furry friends.
  3. Check the Schedule: Dressage and Show Jumping have assigned seating, but Cross-Country is "general admission" around the ropes of the course.
  4. Weather Preparedness: October in Maryland can range from crisp and sunny to rainy and cold. Layers are your best friend.
