The Doble Milla Solidaria "Rettando al síndrome de Rett" is a charity race held in Oviedo, Asturias, starting at Colegio Público La Corredoria. It features short, accessible races: an 800-meter children's run and a 3,200-meter popular race. Entry fees are set at 5 € for children and 8 € for the popular distance.
The funds raised support Rett syndrome research. Participants unable to run can contribute via a Dorsal 0 virtual bib. This marks the event's 12th edition. Aid stations are provided, and the atmosphere is family-friendly, emphasizing local involvement and fundraising over competitive times or a renowned course.
