Our granddaughter was anxious to keep riding her pregnant barrel racing mare. We were worried it might hurt the horse or the foal, so before letting her back in the saddle, I went looking for a straight answer on what’s actually safe.
Can you ride a pregnant horse? Yes — a healthy mare can be ridden through most of her pregnancy, and it’s generally fine for most mares in regular condition. There are generally two windows most horsemen avoid:
- The first 30 days after conception — the embryo is still fragile and attaching to the uterine lining; avoid riding during this window
- The final 2–3 months before her due date — riding becomes impractical and unnecessarily risky as the foal grows and the mare’s body prepares for delivery
Outside those windows, many fit mares are ridden and even competed through month 6–7, with light work continuing close to delivery for some.
This is general guidance, not a substitute for veterinary advice. Every mare is different, and fitness level, age, and pregnancy history all affect what’s safe. Confirm with your veterinarian before riding a pregnant mare, especially if she has any history of pregnancy loss or complications.
About this guide: Based on experience working with broodmares and performance horses, along with established veterinary guidance on equine pregnancy and early embryo development.

Early Pregnancy — Why Riding Waits 30 Days
Breeding domestic horses is goal-oriented — owners are working toward foals with specific characteristics for a particular discipline, and that’s a time-consuming, expensive process. Every precaution in the first weeks protects that investment, including the broodmare herself.
After a mare is bred, the first 30 days are the most precarious of her pregnancy. The embryo is moving through the uterus and attaching to the uterine lining during this window — research on early embryo development confirms how fragile this stage is. A vet can confirm a successful pregnancy by ultrasound around day 14–15, but confirmation isn’t a green light to ride — the embryo remains vulnerable well past that point.
By 30–35 days post-conception, a veterinarian can confirm pregnancy by palpation or ultrasound with more certainty. Most horses are ready to begin light exercise again around day 30–45, though the right timeline depends on the individual mare’s reproductive history and overall condition.
Easing Back Into Work After the First Month
Once riding resumes, ease back in rather than picking up where you left off. All pregnant mares should be brought back into work gradually over the first two months. Fitness level before pregnancy matters here — a mare that was in regular work tolerates a return to riding better than one that wasn’t.
Older mares and overweight horses need extra caution and in some cases shouldn’t be ridden at all during this window. Working them on a lunge line builds fitness without the same stress as riding. Overworking a pregnant mare in early pregnancy can contribute to embryo loss, so stress management matters as much as exercise intensity.
This is also the window to avoid unnecessary stress in general — if your mare gets anxious traveling or loading, skip the trailer trip for now. If she’s herd-bound or reactive around unfamiliar horses, keep her in a familiar setting. Free access to clean water and protection from overheating round out the basics that support a healthy early pregnancy.
Riding Through Mid-Pregnancy (Months 2–7)
Horses carry for about eleven months, and for most of that gestation the foal grows at a steady, manageable pace. A fit mare can typically be ridden — and some are even competed — through roughly month 6 to 8 of pregnancy without issue.
Some mares handle vigorous work through six months with no ill effects. After that, it’s wise to back off the most strenuous exercise — heavy jumping, hard sprints, intense lateral work — while continuing light riding. Every mare is an individual; watch her closely and adjust based on what you observe, not a fixed calendar.
Horseman’s Perspective: I’ve only seen this once, but it’s stuck with me — a friend bred his mare and kept her in active training and racing during part of her pregnancy, planning to put her right back into competition after she foaled. That’s a different decision than light riding through a pregnancy at home; he was asking a fit racehorse to perform at speed while carrying. It worked out for him, but it’s not something I’d casually recommend, and it’s not a one-size-fits-all answer — it takes an exceptionally fit, sound mare, a vet who’s fully on board, and an owner willing to pull the plug immediately if anything changes. Most pregnant performance horses are managed far more conservatively, and that’s the right default for almost everyone.
Keeping a pregnant mare fit generally supports a healthier delivery and faster recovery. Exercise also helps reduce the leg swelling that’s common in later pregnancy, caused by long periods of standing as the mare’s body adjusts to the growing foal.
When to Stop Riding Before Foaling
Energy demands climb in the final trimester as the foal grows rapidly — increase hay and forage accordingly. Most mares, especially those who’ve foaled before, develop a noticeably larger belly in the last six weeks to two months, and riding becomes physically impractical once the saddle no longer fits correctly.
Some mares can technically be ridden right up to the day they foal, but this isn’t advisable — no experienced horseman would recommend it outside exceptional circumstances. Pregnant mares still need exercise in late pregnancy — turnout and lunge line work are the better options once riding stops making sense.
Transporting a Pregnant Mare Safely
Pregnant mares can be hauled safely with the right precautions: a mare comfortable with loading, suitable bedding, fresh water and hay available, and a trailer that’s clean, disinfected, and well-ventilated. Avoid hauling within 30 days of her due date — that window is too close to delivery to risk the stress of travel. For the full mechanics of safe hauling — documentation, regulations, trip prep — see our complete guide to transporting horses.
Hauling a pregnant mare deserves more care than routine transport. Check your tow vehicle thoroughly — tires especially — before any significant trip, and give the trailer a full pre-trip inspection: tires, window function, door latches, hitch, and vents. Map the most direct route available rather than the fastest one if it means avoiding heavy traffic or rough roads, and drive in a way that respects the cargo — no abrupt stops, no hard accelerating, careful turns throughout.
Feeding a Pregnant Mare
A pregnant mare needs nutritious hay and grass, access to a mineral block, and forage with adequate vitamin E and selenium — both essential for the mare and developing foal. Feeding a pregnant horse is more straightforward than many owners assume, and the anticipation of a foal often leads to well-meaning overfeeding of vitamins and supplements that aren’t necessary.
Keep her diet largely unchanged until the final four months of pregnancy. Use the body condition scoring (BCS) system to track her fitness level and adjust rations as needed, ensuring access to high-quality hay or forage throughout. Caloric needs increase notably in the final trimester as the foal goes through its biggest growth period — work with your veterinarian to design a diet specific to your mare rather than following a generic template.
Avoid overfeeding. The instinct to feed a pregnant mare “for two” is common but flawed — it leads to obesity and real health risks. An overweight mare is more prone to laminitis and can face a harder delivery, since fat deposits in the pelvis narrow the birth canal. The core diet stays simple: high-quality hay and clean water, with supplements or vitamins added only after clearing them with your veterinarian — many equine supplements haven’t been tested for safety during pregnancy.
Health and Biosecurity During Pregnancy
Keeping a pregnant mare from getting sick matters more than usual — infections and disease can trigger pregnancy loss, and many medications can’t be safely given to a pregnant mare without risking harm to the foal. Equine herpesvirus (EHV-1) is the pathogen most associated with abortion storms in barn settings, and it spreads easily between horses with no obvious symptoms in the carrier. Isolating a pregnant mare from unnecessary exposure to other horses, especially those recently at shows or new to the barn, is a reasonable precaution, not overcaution.
Horses returning from competitions or shows have been exposed to a wide range of other horses and should be kept away from pregnant mares for a reasonable period. Use grooming tools designated for your pregnant mare rather than sharing equipment across the barn — a simple step that reduces disease transmission risk.
Establish a vaccine and deworming schedule with your veterinarian early in pregnancy. Most vets recommend avoiding deworming in the final month before foaling. Keep her on her regular hoof-trimming schedule throughout — pregnancy is not a reason to neglect routine care.
Signs Labor Is Approaching
A mare that repeatedly lifts her tail and looks back toward her flank as her due date nears is showing one of the more recognizable early labor signs. Owners who know their mare’s normal behavior will notice when something shifts — that change in demeanor is often the first clue.
These signs can begin as early as 24 hours before delivery, but more commonly appear within the final few hours of labor. In that window, watch for lying down and standing up repeatedly, restlessness, pawing the ground, tail swishing, and pacing. Excessive sweating and milk dripping from the teats are among the more obvious signals. Loss of appetite along with more frequent urination and defecation often round out the picture as the date approaches.
Riding the Mare Again After Foaling
Most mares can return to riding six to eight weeks after a standard delivery, though a veterinary check before that first ride confirms the mare is genuinely fit and healthy again. Give her enough time to recover physically and bond with the foal before resuming a riding routine — that bonding period matters as much as the physical recovery.
Once riding resumes, the foal’s needs factor into how and where you ride. Many owners ride the mare with the foal tagging along, staying within familiar territory the foal can handle. Alternatives include leaving the foal to mingle with other bonded horses, or keeping the foal in a paddock within sight so it can keep an eye on its mother while she’s worked separately. Whatever method you choose, keep the foal’s comfort and safety part of the plan, not an afterthought.
FAQs: Riding a Pregnant Horse
Can you ride a pregnant horse?
Yes, for most of her pregnancy. Avoid riding during the first 30 days after conception while the embryo is still fragile, and during the final 2-3 months before her due date. In between, a healthy mare can generally be ridden and many are even competed through month 6-8 of gestation.
When should you stop riding a pregnant mare?
Most owners stop riding 2-3 months before the due date, as the mare’s belly grows and a saddle no longer fits properly. Some mares can technically be ridden up to the day they foal, but this isn’t advisable. Light exercise like turnout or lunge line work is the better option in the final stretch.
Is it safe to ride a horse in early pregnancy?
No, riding should be avoided for the first 30 days after conception. The embryo is still attaching to the uterine lining during this period and is particularly vulnerable to stress. After 30-45 days, most mares can gradually ease back into light exercise.
Can you transport a pregnant mare?
Yes, with precautions. Make sure she is comfortable loading, has suitable bedding, fresh water, and hay, and that the trailer is clean and well-ventilated. Avoid hauling a pregnant mare within 30 days of her due date, since that window is too close to delivery to risk the added stress.
How long after foaling can a mare be ridden?
Most mares can return to riding six to eight weeks after a standard, uncomplicated delivery. Have the mare examined by a veterinarian before the first ride to confirm she is healthy and fit. Give her time to recover physically and bond with her foal before resuming a regular riding routine.
What should you feed a pregnant mare?
A pregnant mare needs nutritious hay or pasture, access to a mineral block, and adequate vitamin E and selenium. Keep her diet largely unchanged until the final four months, when caloric needs increase as the foal grows rapidly. Avoid unapproved supplements and consult a veterinarian for a diet plan specific to her needs.
Why does a pregnant horse keep lifting its tail?
Tail lifting combined with looking back toward the flank is a common sign that labor is approaching. This behavior can begin up to 24 hours before delivery but more typically appears within four to five hours of labor, often alongside restlessness, pacing, and sweating.
Key Takeaways: Riding a Pregnant Horse
- Riding is safe for most of pregnancy — avoid only the first 30 days after conception and the final 2-3 months before the due date
- Stress is the real risk in early pregnancy — not the riding itself, but unnecessary stress (hauling, unfamiliar horses, overwork) during the first month while the embryo is still attaching
- Fit mares can work through month 6-8 — some are even competed during this window, though it’s an individual call based on the mare’s condition
- Feeding stays simple — quality hay, water, and a mineral block cover most needs; caloric demands only rise meaningfully in the final four months
- Transport requires extra care, not avoidance — a well-prepped trailer and careful driving make hauling a pregnant mare safe outside the final 30 days before delivery
- Tail lifting and restlessness signal approaching labor — these signs typically appear within four to five hours of delivery
- Plan to wait six to eight weeks before riding again after foaling — and get a vet check before that first ride back
