About

Cecilia Mattas is a Finnish-born trail ultrarunner and running coach based on the Sunshine Coast, Australia, who rose rapidly through the ranks of Australian trail racing to become one of its top women. She won the Ultra-Trail Australia 100K in 2021 in only her second-ever ultra, then added the Brisbane Trail Ultra 100 Miles in 2023 and Buffalo Stampede 100K in 2024. A dental technician by training, she moved to Australia for an internship and built her coaching practice alongside her racing career through ceciliamattas.com. Her progression from ultra newcomer to multi-race champion in the space of a few years made her one of the most-watched athletes on the Australian trail scene.
