Mia Brookes: The Mathematics of Going Bigger
Standing at the top of the Olympic big air ramp in February 2026, Mia Brookes had a choice: land a trick she knew she could do and probably finish third, or attempt a backside 1620 that would win if it came off and cost her nothing if it didn't. She tried the 1620. She finished fourth. "I could have done a 14 and maybe got fourth or third," she told BBC Sport afterwards, "but I also could have done a 16 and land it and won. But I'd rather be in fourth with a 16 than fourth with a 14, so I'm happy I tried it." It is the clearest statement of her competitive philosophy on record, and it was made in defeat.
Eighteen Months Old on a Snowboard
Brookes was born on 19 January 2007 in Sandbach, Cheshire — a market town in the English northwest roughly two hundred miles from the nearest mountain. She learned to snowboard at eighteen months at the Kidsgrove ski centre in Stoke-on-Trent, where her grandfather worked. Her family later spent five ski seasons in Chamonix, and she trained at the Chill Factore indoor slope in England.
That combination — a dry slope, a family grandfather with a job at a ski centre, and five winters in the Alps — is how Britain produces snowboarders, and it produces very few of them. She joined the GB Snowsport programme at ten and competed at the 2018 British Snowboard Championships at eleven. She attended Sandbach High School and, during the COVID-19 pandemic, studied remotely so she could compete in mainland Europe. Her training bases became Laax in Switzerland, Livigno in Italy and Hintertux in Austria.
Her international debut came in December 2020, when she finished second in a Europa Cup event at Piz Corvatsch. In 2022 she won big air at the Junior World Championships and was runner-up in slopestyle. She was ineligible for the 2022 Winter Olympics on age grounds — a restriction that would look, within twelve months, like a considerable oversight.
The CAB 1440
At the 2023 World Championships, aged sixteen, Brookes won the slopestyle title. She became the youngest snowboard world champion in history and the first British woman ever to win a snowboard slopestyle world title. She did it by becoming the first woman to land a CAB 1440 in competition — four full rotations, executed with a double grab, on a run that had to be linked with the rest of a slopestyle course.
Her reaction, to BBC Sport, was characteristically unadorned: "I'd tried it once before and this is the first time I've stomped it, so I'm super happy."
Crystal Globes
What followed was a three-season run of accumulating hardware. She won the overall big air World Cup title in 2023–24, having taken bronze in big air at Chur in October 2023. In January 2024 she won slopestyle gold at the X Games in Aspen.
The 2024–25 season was her most complete. She took her first World Cup gold in big air at Beijing in December 2024, won back-to-back big air events in Klagenfurt in January 2025, and won the slopestyle World Cup at Laax one day before her eighteenth birthday. She claimed a second consecutive Crystal Globe in big air and, in March 2025, the overall Snowboard Park and Pipe World Cup title — the sport's most comprehensive season-long honour.
Not everything went upward. She finished sixth in slopestyle at the 2025 World Championships in Engadin, defending the title she had won two years earlier, and took bronze rather than gold at the 2025 X Games. In 2025–26 she won a fourth World Cup big air event at Beijing in December and reclaimed X Games slopestyle gold in Aspen in January 2026.
Milan-Cortina
The 2026 Winter Olympics were meant to be the confirmation. They were not. Brookes qualified third for the big air final and finished fourth, with scores of 80.75 and 78.75, having gone for the backside 1620 that did not come off. In slopestyle — her world championship discipline — she failed to qualify for the final at all.
For an athlete who had been a world champion at sixteen and was still only nineteen, an Olympic Games producing one fourth place and one non-qualification is a hard result to absorb. Her response was to defend the decision that cost her the podium, on the grounds that the decision had been correct.
Why Mia Is Called a Genius
Brookes has been described as a snowboarding genius, and the description points at two distinct things worth separating. The first is spatial and rotational control — the capacity to complete four full rotations while grabbing the board twice and still identify the landing. That is craft and nerve, not intellect, and it should be labelled honestly.
The second is more unusual and more genuinely cognitive: she runs an explicit expected-value calculation on every competition run, and she is willing to act on it against her own short-term interest. Her Olympic explanation is the cleanest example. She understood the scoring landscape well enough to know that the 1440 gave her a high probability of a low-value outcome and the 1620 a low probability of the highest-value one, and she chose variance over safety in the biggest event of her life. Most athletes say they think this way; almost none produce the reasoning, unprompted, minutes after finishing fourth. The same logic explains the CAB 1440 at the 2023 World Championships, a trick she had landed exactly once in practice and attempted anyway — and won a world title with.
The counter-case is real. This is judgement within a narrow domain, not general intelligence, and the record includes conspicuous failures: sixth at the 2025 World Championships, fourth and a non-qualification at the 2026 Olympics. A strategy of maximum risk produces exactly this distribution — occasional history, frequent near-misses — and it is legitimate to ask whether an athlete of her talent has left medals on the table. She has one world title, won at sixteen, and has not added a second. What is verifiable is that she has twice moved women's snowboarding forward technically and has been consistently honest about the trade-off she is making.
The Frontier
Brookes turned nineteen in January 2026, which in a discipline where careers can run well into the late twenties leaves an enormous amount of unwritten history. She holds two X Games golds, multiple Crystal Globes, a Park and Pipe overall title, a world championship, BBC Young Sports Personality of the Year and The Sunday Times Young Sportswoman of the Year, both from 2023. What she does not hold is an Olympic medal — the one thing that would settle the argument about whether her approach maximises glory or merely maximises the chance of it. She has at least two more Games to find out, and no apparent intention of playing it safe in either.
