For nearly a decade, the 5.15b (9b) grade stood as the seemingly insurmountable apex of women’s sport climbing achievement. It wasn’t merely a numerical designation; it had evolved into an unofficial yet universally recognized barrier, a benchmark that the world’s most formidable female climbers tirelessly pursued, often reaching its precipice but never quite pushing beyond. This enduring ceiling, established in 2017, created a tangible measure of human limits, defining an era of dedicated progression. Then, in an astonishingly rapid succession of just 14 months, this long-held standard was not only challenged but unequivocally surpassed, not once, but twice, marking an unprecedented leap forward in the sport’s history. The year 2025 witnessed American phenom Brooke Raboutou etch her name into climbing lore by becoming the first woman to conquer 5.15c (9b+), with her groundbreaking ascent of Excalibur in Italy. This monumental achievement, a testament to her prodigious talent and unwavering resolve, sent reverberations throughout the global climbing community. Barely over a year later, in 2026, Slovenian powerhouse Janja Garnbret, already a legend in the competitive arena, mirrored Raboutou’s feat, securing her own 5.15c with an ascent of the iconic Bibliographie in Céüse, France. These two ascents, occurring within such a condensed timeframe, have not only recalibrated the understanding of female potential in sport climbing but have also ushered in a thrilling new chapter for the sport.
A Decade at the Edge: The 5.15b Benchmark
Before the recent breakthroughs, the narrative of elite women’s sport climbing was largely defined by the 5.15b barrier. The year 2017 had been a watershed moment when the landscape of extreme difficulty for women was dramatically reshaped. That year, American climber Margo Hayes made history by becoming the first woman to climb 5.15a (9a+), sending La Rambla in Siurana, Spain. Just months later, Austrian climber Angy Eiter elevated the standard further, achieving the first female ascent of 5.15b (9b) with her send of La Planta de Shiva in Villanueva del Rosario, Spain. These ascents represented a quantum leap, pushing the boundaries that had previously confined the highest female achievements to the 5.14 range. For the ensuing eight years, Eiter’s achievement remained unmatched, solidifying 5.15b as the pinnacle and creating a formidable challenge that captivated the aspirations of the sport’s most elite female athletes. The grade became a symbol of the ultimate physical and mental test, requiring an extraordinary convergence of strength, endurance, technical precision, and unwavering self-belief. Despite numerous attempts by many highly capable climbers, the next step remained elusive, underscoring the immense chasm between 5.15b and the next level of difficulty.
Decoding the Grades: What 5.15c Truly Means
To fully appreciate the magnitude of these ascents, it is crucial to understand the intricate world of climbing grades. In the United States, the Yosemite Decimal System (YDS) is predominantly used for sport climbing, with the hardest routes typically graded from 5.15a through 5.15d. Internationally, particularly in Europe, the French grading system is prevalent, corresponding to 9a through 9c. At this elite level, each incremental step from ‘a’ to ‘d’ or ‘a’ to ‘c’ represents a disproportionately significant increase in difficulty. It is not a linear progression; rather, it signifies an exponential leap in the physical and technical demands placed upon the climber.
A 5.15a route is already a monumental undertaking, achieved by a select few globally. Progressing to 5.15b requires not just an increase in raw strength but often a mastery of highly specific, sustained, and delicate sequences. A 5.15c, however, elevates these demands to an entirely different stratum. Routes at this grade are characterized by exceptionally powerful moves, minuscule holds, precarious balance, and unrelenting endurance requirements, often stretching over considerable lengths. They demand a perfect synergy of every facet of climbing ability, often requiring months, if not years, of dedicated project work, refining beta (the sequence of moves), and pushing physical conditioning to its absolute limit. Historically, 5.15c has been a grade reached by only a tiny handful of male climbers worldwide, with legendary figures like Adam Ondra pioneering its earliest ascents (e.g., La Dura Dura in 2013). The subsequent grade, 5.15d (9c), remains climbing’s ultimate frontier, with only a few proposed ascents, most notably Adam Ondra’s Silence in 2017, and virtually no confirmed repeats, underscoring the extreme rarity and difficulty at this level. Until 2025, the 5.15c grade was entirely uncharted territory for women, representing a formidable, seemingly impenetrable barrier.
Brooke Raboutou’s Pioneering Ascent of Excalibur
In April 2025, the climbing world held its breath as news broke of Brooke Raboutou’s groundbreaking ascent of Excalibur in Italy, making her the first woman to ever climb 5.15c (9b+). This achievement was not merely a personal triumph but a seismic event that reshaped the perceived boundaries of female performance. Excalibur, located in the Arco region of Italy, is a notorious testpiece, first climbed by Italian strongman Stefano Ghisolfi in 2021. Known for its extremely steep, overhanging profile and a relentless series of powerful, dynamic moves on razor-sharp crimps and slopers, it is a route that demands absolute finger strength and an iron will.
Raboutou’s journey to this historic ascent was particularly remarkable because she reportedly bypassed the conventional progression through multiple 5.15a or 5.15b routes, jumping directly from her previous highest grades to tackle the immense challenge of Excalibur. This audacious leap speaks volumes about her innate talent, meticulous preparation, and unwavering confidence. Born into a lineage of climbing legends – her parents, Robyn Erbesfield-Raboutou and Didier Raboutou, were both world-class climbers – Brooke has carved her own path, showcasing a blend of competitive prowess and outdoor project dedication. Her ascent of Excalibur was the culmination of an intense period of focus, physical training, and mental fortitude. In a statement released shortly after her send, Raboutou expressed immense gratitude for the process and the lessons learned, highlighting the profound personal growth experienced during the project. The climbing community erupted with congratulations, recognizing the significance of her achievement in setting a new standard for future generations.
Janja Garnbret’s Unstoppable Rise: Conquering Bibliographie
Just 14 months after Raboutou’s pioneering ascent, Janja Garnbret, arguably the greatest competition climber of all time, further solidified the new frontier with her own 5.15c send of Bibliographie in Céüse, France. This mirrored achievement, coming from a climber with a slightly different trajectory, underscored the profound shift occurring in women’s climbing. Garnbret, a two-time Olympic medalist and multiple World Champion, had long dominated the indoor competition circuit, showcasing unparalleled consistency and technical brilliance. Her transition to tackling one of sport climbing’s most iconic and demanding outdoor testpieces marked a significant expansion of her already legendary career.
Bibliographie, a masterpiece of natural rock climbing, was first ascended by German climber Alexander Megos in 2020. Situated on the legendary cliff of Céüse, known for its pristine limestone and historical significance in sport climbing, Bibliographie is a route defined by its long, sustained sequences on small, sharp holds, demanding extreme precision, body tension, and endurance. It is a true benchmark at the 5.15c grade, revered for its aesthetic beauty and unforgiving nature. Garnbret’s successful redpoint of Bibliographie demonstrated her exceptional versatility and adaptability, proving that her indoor dominance translated seamlessly to the unforgiving demands of outdoor rock. Her methodical approach, characteristic of her competitive background, involved detailed beta analysis and relentless physical conditioning tailored to the route’s specific challenges. Following her ascent, Garnbret reflected on the deep connection she felt with the route, describing it as a project that left an indelible mark long before she clipped the chains. Her success was celebrated not just by her native Slovenia but by climbers worldwide, who recognized it as a testament to her unparalleled athletic ability and mental strength.
The Acceleration of Progression: A New Era
The most compelling aspect of these two historic ascents is not merely that 5.15c has been climbed by women, but the astonishing speed with which the second ascent followed the first. For eight years, 5.15b seemed to be the impenetrable ceiling. Then, Raboutou shattered it, and little more than a year later, Garnbret confirmed that it was not an isolated incident but a sign of a new era. This rapid succession of breakthroughs is a common phenomenon in climbing progression. A grade can appear untouchable, a theoretical limit of human capability, until one individual manages to unlock its secrets. Once that psychological and physical barrier is breached, the once-impossible begins to look attainable, inspiring others to redouble their efforts and re-evaluate their own potential.
This pattern suggests a significant shift in the collective consciousness of elite female climbers. The precedent set by Raboutou and Garnbret has likely demystified the 5.15c grade, transforming it from an abstract concept into a tangible, achievable goal. It will undoubtedly motivate a new wave of strong female climbers to set their sights higher, pushing their training and mental fortitude to unprecedented levels. This acceleration of progression hints at a vibrant future where the boundaries of women’s sport climbing will continue to be redrawn with increasing frequency.
Beyond the Grades: Impact on the Sport
The implications of these ascents extend far beyond the numerical grade itself. Raboutou and Garnbret have not only elevated the standard of women’s climbing but have also significantly enhanced its visibility and appeal. Their achievements serve as powerful sources of inspiration, particularly for young girls and women entering the sport, demonstrating that the highest echelons are within reach. This increased visibility can lead to greater investment in women’s climbing, from sponsorships and media coverage to dedicated training programs and coaching.
Moreover, these ascents challenge long-held assumptions about physical differences and perceived limitations in climbing. They underscore that with dedication, optimal training, and mental resilience, women can achieve levels of strength and skill previously thought to be exclusive to men at the sport’s highest grades. The convergence of Garnbret’s competition-honed strength and Raboutou’s outdoor project focus highlights the diverse pathways to elite performance, enriching the sport as a whole. It fosters an environment where innovation in training and technique can flourish, benefiting all climbers.
Gazing Towards the Summit: The 5.15d Frontier
With 5.15c now established as the new benchmark for women, the natural question arises: what about 5.15d (9c)? This ultra-elite grade, currently pioneered only by Adam Ondra with Silence, represents the absolute cutting edge of human climbing potential. The speed with which 5.15c fell twice suggests that 5.15d may not be as distant a prospect for women as previously imagined. The psychological barrier has been broken, and the blueprint for progression has been laid. While the leap from 5.15c to 5.15d is another monumental step, requiring even greater specificity in training and perhaps a perfect confluence of conditions, the climbing world is now poised to witness who among the next generation of female climbers will dare to dream of this ultimate frontier. The era of women pushing into the highest echelons of sport climbing has definitively begun, promising an exciting and unpredictable future for the sport.
