Thousands of children go missing every year in Belgium, but only a few people are really looking out for them. At the same time, over 1,3 million active Strava users log their miles across the country throughout the year. How do we tap into this community and give their runs a purpose that goes far beyond Kudos?

Casemovie2026 Miles For The Missing v017 Cannes Version
Miles for the Missing is not a campaign. It’s a new and sustainable channel to boost the search for missing children whenever needed. Leveraging a community of runners that is already out there and inspiring them to discover new paths to turn Belgium into a heatmap of routes with eyes on the ground.

Facing a 22% rise in missing child cases, Child Focus urgently needed to raise awareness and mobilize a vast public resource to help find these children. The problem? The effectiveness of traditional alerts is in decline due to digital saturation. And whenever people do come across a missing child poster, apathy sneaks in. Fueled by the feeling that there’s no way for them to make a difference. While in fact they easily can. Just by keeping their eyes open. Because the general public is an important source for leads when a child goes missing. 

Runners already cover Belgium. With over 1.3 million active Strava users logging millions of miles across the country every year, the nation's running community represented an untapped search network, one that moves through the exact streets, parks and neighborhoods where extra eyes are needed most. Therefore runners are natural searchers. They consciously or unconsciously check their environment while covering whole areas. They were already doing the work; we just needed to remind them that their eyes still matter and give a gentle but powerful nudge to use their powers for our cause during their pastime. 

We tapped into the existing community of runners by creating ‘Miles for the Missing’: a Strava running club that transforms active runners into a permanent, mobile search network. By joining the club, runners receive urgent missing children alerts directly on their smartphones, turning every run into a potential search opportunity. But runners are creatures of habit, often covering the same familiar routes. That's why an AI-powered route generator was built to invert live Strava heatmap data, identifying the "cold spots" where runners rarely go, and guiding members along entirely new paths past high-probability locations like bus stops, train stations and gas stations, the places where a vital clue is most likely to be found. The club was launched on International Missing Children's Day at the 20km of Brussels, the initiative immediately captured national attention. Celebrity runners amplified the cause. A nationwide DOOH and social campaign broadened its reach beyond the running community.

In a matter of time, the club went from zero to Belgium's #1 running club with 12,638 active members, 4,6 million km covered, €204,000 in earned media, and a permanent, zero-cost search channel. Alive, active, and ready to mobilize at a moment's notice.
