Mission Accomplished: CyanoShark Supports Successful European Championship at Challenge Almere-Amsterdam Triathlon

Challenge Almere-Amsterdam triathlon and CyanoShark


We’re delighted to report that all swimming events at Challenge Almere-Amsterdam took place successfully in the Weerwaters of Almere, following our intensive pre-event water quality management programme.

Ten Days of Proactive Water Treatment

For ten consecutive days leading up to the Challenge Almere-Amsterdam triathlon, incorporating the European Championship Long Distance, our CyanoShark system was deployed daily on the swimming course. Over more than 50 hours of active operation, the team and CyanoShark worked tirelessly to disrupt cyanobacteria concentrations and mitigate potentially hazardous blue-green algae levels in the lake.

While cyanobacteria levels are influenced by numerous environmental factors including weather patterns, sunlight exposure, rainfall, and wind conditions; all of which remained beyond the event’s control, our sustained intervention played a crucial role in reducing the risk levels and creating safer swimming conditions for Europe’s and the Netherlands finest triathletes.

Collaborative Success

The successful outcome demonstrates what can be achieved when innovative technology meets proactive event management. We were pleased to play our part in supporting Challenge Almere-Amsterdam and are particularly grateful to the Challenge Family for taking the lead on this important water quality initiative.

Their commitment to athlete safety, combined with their willingness to deploy cutting-edge, environmentally responsible solutions, sets a new standard for sustainable event management in challenging conditions.
