Biel Ràfols, born in Barcelona in 1987, is recognized as a pioneer of the 'camera-runner' a term he coined to describe his unique method of filming trail running. He began his career by capturing the essence of the sport with basic equipment, primarily focusing on the runners' interactions with nature, the challenges they face, and the emotional highs and lows of competing in harsh environments. His early work consisted of following mountain runners with standard cameras, highlighting the beauty and difficulty of trail running beyond just the finish line.

Over the years, Ràfols has adapted his filming techniques to meet the demands of a rapidly growing sport. As trail running gained popularity, he began seeking out alternative filming locations to avoid overcrowded areas and deliver a fresh perspective. His work demonstrates the importance of capturing the untamed spirit of the trails; he emphasizes that filming is not just about documenting the finish line but about showcasing the runners' journey through rugged landscapes and dynamic weather conditions.

Ràfols' unique contributions have helped elevate the visibility and understanding of trail running, illuminating the physical and mental resilience required from participants. His journey from a wedding videographer to a vital figure in the extreme sport documentation highlights the evolving role of technology and creativity in sports coverage, defining a new narrative style that resonates with both athletes and audiences alike.
