The Sant Silvestre d'Almussafes is a 5 km running event held in Almussafes, Valencia, Spain, at the end of December, serving as a year-closing race. The primary 5k race is open to participants aged 13 and older. The event also features children's races, making it suitable for families rather than solely a standard road race.
The event utilizes professional chip timing managed by Cronorunner S.L., providing a proper race-day setup for the short distance. Listings also indicate it is non-competitive, suggesting a local and festive atmosphere over a highly competitive one. The Sant Silvestre format offers runners a straightforward way to conclude the year with a run.
