Great Green Run 2023 (GGR 2023), a sustainability-themed running event, will take place on 24 September 2023 at the Marina Barrage. Two race categories – 5km and 10km – with routes around the Bay East Garden are open for participation in this edition. Apart from the runs that will flag off in the evening, a host of activities from yoga demo, mass healthy boxing, magic show, and a Out of the Blue event organised by the Sustainability Singapore Gallery will keep all runners and visitors engaged on that Sunday morning. Runners also stand a chance to win great prizes such as overseas trips and bikes in a lucky draw held at the end of the day.
