Hernandez-Cervellon began her sporting career as a BMX racer in international competition before discovering snowboarding. On 21 October 2002 she experienced an attack of multiple sclerosis that paralysed her legs for two months. As a result, she stopped sport and took refuge in writing, publishing two books for Éditions du Rocher and working for Europe 1 and Le Figaro from 2012, covering the 2012 Summer Paralympics in London. In May 2012, Hernandez-Cervellon arranged an endurance race for both disabled and able-bodied athletes, travelling from Lyon to Bordeaux by bicycle and kayak. Then, in 2013, when she happened to try snowboarding again in the French Alps, she was spotted by a member of the French para-snowboarding team. She was selected for the Paralympic snowboarding team for the Sochi Games in February 2014, with just over a month to prepare, but was encouraged by her performance at the World Para Snowboard World Cup the previous month. She won a silver Paralympic medal at Sochi, with a snowboard cross time of 2:07.31, and was named a knight of the National Order of Merit by then-president François Hollande in June 2014. In the 2014–15 season, Hernandez-Cervellon won the with all stages of the World Para SnowboardWorld Cup in both snowboard cross and banked slalom; leading her first full season gained her a Crystal Globe and she ended the season at La Molina crowned world champion in banked slalom and with a silver medal in snowboard cross. In 2015–16, still competing for the Les Angles, Pyrénées-Orientales team, she won 10 races in the European and World Cups and 2 further Crystal Globes — a gros globe for leading the World Para Snowboard rankings and a petit globe for first place in the banked slalom — as well as the silver medal for snowboard cross. On 4 February 2017 at Big White, she won another silver medal in snowboard cross, winning the banked slalom silver 3 days later. At the end of the 2016–17 season the following month, with 7 spots on the podium, including 5 victories, she won a third gros globe and both petits globes for snowboard cross and banked slalom. She joined the France Douanes team on 20 January 2017 with the aim of travelling to PyeongChang as a part of the French Paralympic team for the 2018 Winter games, where she won bronze in the snowboard cross and silver in the banked slalom.
