Mégocup Sport Planète
A 2-hour simultaneous cigarette-butt collection 'sport' challenge where French cities mobilize teams to beat a shared world record. Includes recycling pipeline via TchaoMégot.
Cities run in parallel and report city-level totals; the aggregate goes toward beating a world record, with per-city collection numbers compared publicly. Civic-pride angle.
Each city's event is staffed by local volunteer teams (often partnered with Hebdo Ecolo or local sport clubs), turning into a team-bonding social event. Local mayors and sport associations rally residents.
French-language, narrow vertical (cigarette butts specifically). A microcosm of how a single-purpose challenge can produce synchronized inter-city competition. Recurring with growing city count.
