OCR Venom Run — Kostreš hills (historical 2025)

Reports and event feedback

• Selected 2025 Kostreš winners — turnout and difficult rope climbing ↗

  Sara Petak and Aleksa Vuković / Derventa Cafe interviews · 2025

  Petak describes a demanding race and finds rope climbing particularly difficult because it requires technique as well as strength. Vuković praises the turnout and is pleased with his performance in the competition.

  Complete original raced report, both selected winner exchanges, organizer context and conclusion read. Published 22 March 2025 and explicitly set on the hilly Kostreš course. The two competitors are one containing interview publication, not two independent sources or a representative aggregate. Their ages, exact entry classes and funding are unstated. The organizer homepage checked in 2026 lists both as ambassadors; their exact relationship at the 2025 race is unknown. Source nationality labels conflict and are not adopted. Finishing places, times, training and self-described credentials are not satisfaction ratings. These historical opinions do not rate the unresolved 2026 Derventa properties. No numerical overall is given.

OCR Venom Run

• The municipal report published 22 March 2025 explicitly says the race took place that day in Kostreš, a settlement in the Derventa area. The local report independently names the hilly Kostreš terrain. No precise start address is verified.
• The city describes about six kilometres and more than twenty obstacles; Derventa Cafe describes slightly less than six kilometres and more than twenty-five. These are source estimates, not surveyed measurements or a single reconciled obstacle count. The children’s race is separate.
• The organizer’s 2026 Derventa city programme contains different, conflicting named properties. Its homepage testimonials have no verified edition/property and are not treated as Kostreš reviews. The selected 2025 winner interviews concern the historical hills course.
• These are historical or last-listed programme facts, not confirmation that registration is open. No later programme, exact start coordinates or unchanged route is verified.
