Running

Spetses Mini Marathon. At this mid-October running event, you can choose between a 5K (3.1-mile) and 10K (6.2) fun run or a more demanding 25K (15½ miles), though the latter is also more scenic, taking in a whole lap around the island. You can also take part in the demanding endurance swimming competitions taking place over the same weekend: a 3-km (1.8-mile) race from Kosta to Spetses and a 5-km (3.1-mile) round-trip to Kosta and back. There are also runs and other activities for the young members of any group or family. Spetses Town, Spetses. 22980/72244; www.spetsesmarathon.com.
