JBL Triathlon Sieraków 2026

Set your course for the charming little town of Sieraków, nestled in the spectacular region of Greater Poland 🇵🇱. The festivities invite you to take on a legendary race that’s a must on the national calendar: the famous JBL Triathlon Sieraków. Forget any hopes of a perfectly flat course—the bike profile is renowned for its leg-breaking little roller-coaster climbs. Your body will have to manage its reserves and absorb sharp surges if you want to tame this particularly demanding terrain! ⏱️

Your epic kicks off with a real thrill: a magnificent swim in the crystal-clear waters of the stunning Lake Jaroszewskie. Once you’ve peeled off your wetsuit and are firmly settled on your machine, the asphalt launches you into scenery of absolute purity. Your effort will have you riding on winding roads snaking through immense pine forests and vast, unspoiled protected nature reserves. The immersion forces you to keep steely focus on the climbs before punching hard on the descents, then ditching your bike for the run . The running route drops you straight into the cool undergrowth, offering you a saving shade to calm your overheating engine all the way to the final meters 🚴‍♂️.

Adrenaline fills the clean air within a huge group bringing together thousands of passionate triathletes. The atmosphere oozes authenticity and communion with nature. Families and volunteers gather along the sandy shores and in the clearings to cheer you on loudly, carrying you on their voices toward the final arch. A wildly festive vibe welcomes you at the finish, where local pride blends with the joy of achievement 🏅.

Save one last hint of energy to flop down on the sand beach of the lake or down a well-deserved beer with your fellow grinders. Clip in and dive into the adventure! 💥
