Omloop Goeree-Overflakkee is a walking-event organization run by Stichting Omloop Goeree-Overflakkee, based in Ooltgensplaat in the Netherlands. Its flagship event is a long-distance walk around the island of Goeree-Overflakkee, bringing together participants, local residents, visitors and volunteers. The 2027 edition, scheduled for 27 and 28 August, will offer a 110-kilometre Long Distance Walk and an 80-kilometre Kennedymars.

The organization describes the 110-kilometre route as one of the largest events of its kind in the Benelux and aims to support walkers along the way with encouragement from the event team and island community. Its website provides route and distance information, preparation guidance, frequently asked questions, participant rules, visitor information and direct registration. It also invites people to volunteer and offers information about sponsorship.

In addition to the main event, the site features the Oliebollentocht and highlights the Waterpoortloop as another walking event. The organization’s activities celebrate endurance walking and community involvement on the island
