Oinousses Run is a small island race day on Oinousses, near Chios, featuring both running and cycling. Runners can select between 5 km and 13 km, while cyclists compete in a 21 km event. Chios Cyclists and the Municipality of Oinousses organize the race, with a 150-athlete limit due to ferry capacity.
The race begins and ends in the island's center. The running course incorporates coastal paths and traditional island sections. The 13 km route includes a more challenging segment past the historic Monastery of Evangelismos and offers views toward Chios. It is designed for experienced runners seeking a demanding course, though the shorter distance and a walking option accommodate beginners.
