On Saturday 18 July 2026, Sophie Fouracre, aged 34, was fatally injured in a cross-country accident riding Rhubarbsfox Brittania at Swalcliffe Park in Oxfordshire. Hours later, at Penrith in Cumbria, Kerry Donoghue, aged 42, died following a cross-country accident riding Carneyhaugh Rua. Medical teams at both venues responded immediately. Neither rider could be saved. Both horses were examined by attending veterinary teams and found uninjured. Both events were abandoned for the remainder of the weekend.
Rosie Williams, Chief Executive of British Eventing, said the loss of two members of the eventing community on the same day was almost beyond words, and that the sadness would be felt across the sport for some time to come.
The sport has spent more than two decades engineering against exactly this outcome. The research record is substantial, the investment real, and the results measurable. Understanding what that work has achieved — and what it has not — is the only useful response available to anyone who cares about where this sport goes next.
The Fall That Matters Most
Not all falls carry equal risk, and the difference is not marginal. FEI Risk Management Program data covering 2016 through 2025 shows that unseated rider falls resulted in serious injury in approximately one of every 76 cases. Rotational horse falls — where the horse somersaults over the fence, frequently landing on the rider — resulted in serious injury in approximately one of every five.
That single ratio has shaped nearly every safety intervention in the sport since 2002. Rotational falls are also implicated in equine outcomes: research indicates that 37.3 percent of equine fatalities in eventing are associated with a reported horse fall during the cross-country phase.
What the Engineering Has Achieved
The frangible pin emerged from work at the Transport Research Laboratory, which developed a mathematical model and built a crash-test horse to study impact forces. The first pins were trialled at nine British Eventing horse trials in 2002, including Badminton, and were fitted to all new suitable fences at every level of British competition ahead of the 2006 season. The pin is designed to drop a fence's top element by at least 20 centimeters when struck from above, giving a horse the chance to get a foreleg forward and avoid rotating.
The MIM clip, invented by Swedish engineer Mats Bjornetun and approved by the FEI in 2012, addressed the pin's central limitation. Research by Anders Flögård found that the forces involved in a rotational fall are initially horizontal, followed by vertical. The MIM clip breaks under horizontal impact, allowing the rail to fold forward in the same direction as the horse's travel, reducing rotational speed. Critically, it works on fence types the pin cannot serve — walls, gates, arrowheads. British Eventing approved the system in 2016 and supplies the kits to organisers free of charge, as it does with frangible pins.
The numbers moved. In 2008, FEI data recorded one rotational fall per 322 starters. By 2019, that figure had improved to one per 805 starters. FEI Risk Management data shows rotational falls have decreased consistently since 2016. At the 2025 FEI Eventing Forum, sessions led by David O'Connor, Geoff Sinclair, and Stuart Buntine reported that horse falls have decreased overall, with a significant reduction in rotational falls attributed to advances in course design, education, and technology.
Research from the University of Kentucky by Shannon Wood, completed under Professor Suzanne Weaver Smith in the College of Engineering, modelled rotational fall probability at specific fences. Using body positions and speeds from a vertical at the 2018 Land Rover Kentucky Three Day Event, the model predicted that 64.9 percent of horses contacting the fence with the upper foreleg would not rotate. With a device limiting impulse to 900 newton-seconds within a defined activation range, that figure rose to 96.4 percent.
The Limits
FEI data for 2025 recorded 15 rotational falls, of which three — 20 percent — resulted in serious injury. Twenty-two serious or fatal injuries were reported across the year. Rotational falls have declined; the proportion producing catastrophic outcomes when they occur has not.
Analysis presented in the FEI's independent audit conducted by Charles Barnett found that fence-related factors account for less than 10 percent of the variability in horse falls. Horses involved in rotational falls were more likely to have hit the fence hard and on the way up. Riders in rotational falls were more likely to have approached at an inappropriate speed — too fast or too slow. Engineering the fence addresses a genuine but bounded portion of the problem.
The protective equipment picture is more uncomfortable still. A 2016 study by TRL and British Eventing, presented at the International Research Council on the Biomechanics of Injury and involving British Eventing national safety officer Jonathan Clissold, dropped an equine cadaver onto an instrumented crash-test dummy. The air jacket reduced predicted risk of severe chest injury from 94 percent to 81 percent. The study concluded that fatal and serious injuries remain highly likely when a horse falls directly onto a rider.
A larger retrospective analysis by researchers at the University of Melbourne and the University of Sydney, led by Lindsay Nylund, examined FEI cross-country fall data from 2015 through 2017 — 1,819 riders who fell wearing air jackets against 1,486 who fell without. Riders wearing air jackets had 1.7 times the odds of sustaining a serious or fatal injury. The authors were explicit that this does not establish that air jackets cause harm, and identified confounding possibilities: riders at higher risk may be more likely to wear them, deployment forces measured between 150 and 593 newtons may alter fall trajectory, and inflation may impede a rider's ability to tuck and roll. US Equestrian's own guidance acknowledges the study raised unanswered questions requiring further research.
The Cost Question
At the 2025 FEI Eventing Forum, discussion of frangible technology surfaced a practical obstacle: the high cost of advanced safety equipment, the need for consistent training of course builders, and a proposal for a fund to subsidise frangible fence costs. British Eventing supplies kits free to organisers. Not every national federation does.
There is also the penalty debate. FEI competition applies 11 penalties for activating a frangible device. British Eventing national classes apply none. The Forum's consensus was that reduced rotational falls justify the trade-off of soft activations, but the tension is real: a penalty structure that discourages activation works against the device's purpose.
What Remains
British Eventing describes itself as a world leader in safety research and implementation, and the record supports that. Its recording systems hold details of every cross-country fence on every course and every fall that occurs at them. Frangible technology has been mandatory on suitable fences since 2006. The sport has done more measurable work on rider safety than most equestrian disciplines have attempted.
And two riders died on the same July afternoon.
The honest reading of the research is that engineering has substantially reduced the frequency of the most dangerous fall type while leaving its severity largely intact, and that the human factors accounting for the majority of fall variability — approach speed, preparation, the judgment of whether a given horse and rider belong at a given level on a given day — have proved far harder to engineer than the fences themselves. That is not an argument against the technology. It is an argument that the technology was never going to be sufficient on its own, and that treating it as the answer is its own kind of risk.
