Ten years ago, a loose association of Rotarians fielded a team that rode in El Tour de Tucson and raised about $10,000 ($30,000 if you include the match by the Bill & Melinda Gates Foundation). Eighty-five cyclists came to Tucson in 2018 from as far away as France and Australia. Cumulatively since the idea was birthed, the ride has raised over $53.3 million.
