The Doble Milla Solidaria - Sindrome RETT is a small charity running event held at Colegio Publico La Corredoria in Oviedo, typically in November. It raises funds for Rett syndrome research, maintaining a straightforward format: an 800-meter children's race and a 3,200-meter popular race for older participants and adults.
The event is designed for families, not just competitive runners, with children, local residents, and supporters participating together. Those not running can contribute via a Dorsal 0 donation. Participants receive refreshments post-race. The program also features a gift raffle, contributing to the day's atmosphere as a school-community fundraiser rather than a typical road race.
