Jill Holterman

Dutch long-distance runner

Jill Holterman changed course and quit her job as a lawyer to focus more time on her sport, the marathon. Jill set the bar high by qualifying herself on 18 April 2021 in the Enschede Marathon for the 2020 Olympics with a personal best of 2h28:18.

Jill competes in STOX Energy Socks to keep pushing limits and realizing her dreams. “Sometimes people ask me: why are you doing this? For who? Well, I do this for me. Because I love running and seeing how far I can go, how much I can push my own limits. I love the feeling of running, it makes me feel free.”
