Holy Cross Ironman Supermarathon 2026

Get ready for a challenge that separates enthusiasts from true "people of iron". The Holy Cross Ironman Supermarathon is not an ordinary race – it’s an ultra hiking or running marathon that challenges you over a distance of about 100 kilometers. The route leads through the most demanding and technically rugged sections of the Świętokrzyskie Mountains, including the legendary scree fields, steep climbs up to Holy Cross and the Jeleniowskie range. This is an event for those who love mud, rocks, nighttime battles with their own psyche, and unpredictable weather. Here you don’t fight only against the clock, but against the spirit of the Świętokrzyskie Mountains, which doesn’t forgive a lack of humility 🏃‍♂️⛰️🌑.

When after a dozen (or several dozen) hours on the course you finally cross the finish line, your body will demand a hero’s rest. The Świętokrzyskie region has prepared the best "remedies" for the occasion:

Holy Cross (Łysa Góra) – if you still have the strength in your legs to look back on the route, this sanctuary is a place with incredible energy. The view of the scree fields from the viewing platform lets you grasp the scale of the difficulty you’ve just overcome. It’s a place of calm that perfectly contrasts with the race-day adrenaline ⛪⛰️.

Mineral Pools in Solec-Zdrój – an absolute "must-have" after Twardziel. Although it’s some distance from Kielce, nothing regenerates battered muscles and joints like a soak in the world’s strongest sulfide water. It’s professional recovery that will get you back on your feet faster 💦🛀.

Kadzielnia in Kielce – located in the very heart of Kielce, this former quarry is now an amphitheater and a recreation park. A walk along the local boardwalks over the water’s surface is a great way to very gently "walk off" the soreness amid spectacular limestone cliffs 🧗‍♂️🌊.

A feast at Baba Yaga’s – after burning 6,000–8,000 calories on the course, you need to eat something substantial. Świętokrzyskie zalewajka made with real sourdough starter, with lots of mushrooms and bacon, is a culinary legend that will get you back on your feet. Add local dumplings with buckwheat groats and farmer’s cheese – that’s the fuel your muscles need to rebuild 🍲🥟.

Remember that Twardziel Świętokrzyski is a race where finishing the course is a victory in itself. This is where character is forged and lifelong friendships are born, formed while tackling nighttime kilometers together. Are you ready to prove you deserve the title of Twardziel? 🏁
