Glens Runner Mark O'Dell has long been known as a pursuer of extreme challenges and type 2 fun. His latest ridiculous achievement, completed this weekend, is one of the toughest endurance challenges on the planet — the Jánošík - Slovak Xtreme Triathlon in Slovakia, an absolute epic that demands everything from body and mind.
The race began at midnight on Friday, with athletes jumping from a boat into the darkness and tackling a 2.4‑mile swim across a lake. From there, Mark settled into a brutally long cycle: 110 miles featuring 7,400 ft of climbing, with wife Lucy providing support from the crew car throughout. To finish, Mark faced a monstrous final leg — 26 miles of mountain running with 9,400 ft of ascent 🤯 Lucy joined him again for the last 17 miles, helping him through 6,000 ft of climbing as the race pushed into its final, punishing hours.
An extraordinary achievement from Mark, and a brilliant effort from Lucy in support. This was endurance in its purest form — courage, grit, and teamwork from start to finish. Chapeau! 🎩
