Olympic bloodlines up top, Ribot’s engine underneath, and a five-time repeat cross that keeps proving itself.

Some mares are nice. A few are genuine goldmines for a modern sport horse breeding program — and Lady’s Comet is one of them. Analyze her pedigree and you find a flawless combination of powerful dirt athleticism, elastic European turf blood, and the renowned “chef-de-race” sires who built the modern Thoroughbred. Cross her with the Class 1 Connemara stallion R Blue Moon, and the two pedigrees don’t just complement each other — they reinforce each other, line by line.

The Sire Line: Comet Shine (CAN)

Lady’s Comet’s sire, Comet Shine, was a powerful, masculine individual known for exceptional movement. Commercial racehorse breeders overlooked him — but sport horse breeders didn’t. He carved out a legendary reputation as a premier sire of sport horses, and his daughter carries his best blood close up.

The “Courageous Comet” Effect

Comet Shine famously sired Courageous Comet, Becky Holder’s 2008 Olympic and 2010 World Equestrian Games partner and winner of the Rood & Riddle Thoroughbred Sport Horse of the Year award. This is not a pedigree that merely looks like it can event — it has already done it, at the highest level on earth. The line consistently throws the bold mind, scope, and elite gallop that upper-level eventing demands.

Fappiano / Mr. Prospector Power

Through Fappiano, Comet Shine introduces massive bone, excellent hindquarter power, and a clean, correct hock. In sport horse breeding, Fappiano lines are highly sought after for exactly this: elasticity and raw scope over fences, built on bone that holds up to the work.

Vice Regent / Northern Dancer Elasticity

Her paternal granddam, Hangin On A Star, brings in Vice Regent — and with him, dense Canadian and European turf athleticism, excellent tracking at the walk, and the kind of joint longevity that keeps a sport horse sound season after season.

The Dam Line: Lady Coffee, by Star Choice

If the sire line brings the brilliance, the bottom side of Lady’s Comet’s pedigree brings the anchor — refinement and structural correctness, in a package that makes her a stellar cross for the shorter, more compact Connemara frame.

In Reality: The Structural Cornerstone

In Reality, sire of Star Choice, is a cornerstone of modern American sport horse lines. Warmblood and crossbred breeders prize him for one thing above all: an incredibly strong loin connection, a short, flat back, and unmatched structural soundness. These are the traits that decide whether athleticism stays usable for a twenty-year career.

His Majesty / Ribot: The Engine Room

Through her granddam Magic Toss, Lady’s Comet inherits the legendary blood of His Majesty and Ribot. Ribot lines are famous in international show jumping and eventing for immense courage, a powerful “engine” in the hind end, and an intense, focused work ethic — horses that want to go forward and jump.

Turn-to / Bold Ruler Stamina

Further down the page, First Landing (by Turn-to) and Bold Ruler guarantee the horse stays light on its feet, with a high, naturally balancing neck set.

The Cross: Lady’s Comet × R Blue Moon, Structure by Structure

Line up the two five-generation pedigrees and the reinforcement is striking. Blue and Lady’s Comet balance each other’s frames while doubling down on world-class jumping talent and baseline mechanics.

1. The Loin and Topline

The classic risk in breeding Half-Bred sport horses is the topline: Thoroughbreds can throw a longer, weaker loin coupling, while Connemara ponies can trend toward a lower neck set or flatter croup.

• The mare: Lady’s Comet brings Fappiano and In Reality close up — a short, strong back with a powerful, seamless loin connection, plus Fappiano’s bone density and deep, sloped hip.
• The stallion: Blue counters with the classic, robust Connemara topline — a strong, well-muscled loin and a naturally high, clean neck set.
• The result: A short, strong back that transfers power effortlessly from the hindquarters through the body — the prerequisite for upper-level dressage collection and high-stakes show jumping alike.

2. The Hind Engine

• The mare: Lady’s Comet supplies the scope, heart, and galloping stamina of the His Majesty / Ribot line — raw jumping power and the courage to use it.
• The stallion: Blue packages that energy structurally: clean, dense bone, short cannons, excellent hock placement, and the snappy, active hock action ponies are famous for.
• The result: A hind end built for vertical thrust and long-term stamina, with the quick hind-leg articulation to snap up cleanly over a fence.

3. The Front End and Movement

• The mare: Through Comet Shine, Lady’s Comet carries a heavy dose of Vice Regent — a famously free, loose shoulder, exceptional overtrack at the walk, and natural suspension at the trot.
• The stallion: Connemaras are natural trotters with high knee and hock flexion. On a flat-moving mare that can produce a disjointed gait — but Lady’s Comet’s elastic turf suspension blends with the pony stride instead of fighting it.
• The result: Blue adds knee elevation and quickness up front while Lady’s Comet preserves the Thoroughbred’s reach and swing — a lofty, round, rhythmic trot that is highly marketable in the modern sport horse.

The Bottom Line

This is a textbook nick: elite, elastic Thoroughbred athletic lines over the foundation strength of a Class 1 Connemara. Courageous Comet’s Olympic sire line, Fappiano bone, In Reality’s iron loin, and Ribot’s engine — all of it anchored by Blue’s Premium, performance-proven pony mechanics. On paper, the Lady’s Comet × R Blue Moon foal is exactly what today’s eventing and jumper buyers are looking for: scope, soundness, movement, and a mind that wants the job.

That foal is what buyers mean when they search for a Connemara Sport Horse, a Connemara Half-Bred, or a Connemara Thoroughbred — a Thoroughbred mare crossed with a Connemara Stallion.
