Every autumn the Hartstichting organizes the 11-Strandentocht (11 Beaches Tour), a performance walk along eleven Dutch seaside resorts. Individual participants and teams run, hike or 'kluun' the entire or part of the tour and are sponsored for this. The proceeds from this recreational walk along the Costa Holandesa is used for research by the Hartstichting (the Heart Fund).
Because craft stamps are no longer up-to-date, the organization was looking for a more advanced way of registering the runners' crossings. The tried and tested "marathon" method, with sensors, would be too expensive to achieve the highest possible yield.
That is why we came up with an affordable alternative, configured a registration system and supplied the equipment for the digital stamp posts for the past two editions. The 2222 participants had their wristbands scanned there. We published the transit times of the runners on a personal internet page.
