Blue Reach
Every crossing funds the reefs. Every metre swum matters.
— Caroline LüthiExtreme crossings. Real science. Real stakes.
Blue Reach is Caroline’s multi-year programme linking ambitious open-water crossings to environmental fundraising and awareness. Each challenge raises support for Science4Reefs — a CNRS-backed foundation protecting coral ecosystems in French Polynesia — and feeds educational content into Swiss schools.
