Sarah Hartley

Sarah started running at University in 2018, after talking to a friend and wondering if they could run 5k in one go. After that first 5k Sarah hasn’t stopped, joining The Running Channel in 2020 and going on to document her first marathon and ultramarathon. Sarah broke 20 minutes for 5k in 2025 and became a World Record holder for the World’s Deepest marathon, tackling 26.2 miles in a mine in Sweden. Sarah says: “Running has given me the escape I need when life gets hectic and it somehow never gets boring, even after 4 hours in a pitch black mine, there is fun to be had!”
