The nation's largest night marathon has a new sponsor and name. OSIM, the healthy lifestyle brand, was announced today as the title sponsor, with the annual event - to be known as the OSIM Sundown Marathon - to be held on July 4 at the F1 Pit Building.

There will be four race categories instead of the existing three. The 5km fun run, for competitors aged 6-16, has been added to the existing 10km, half marathon and full marathon events.

The new category is intended to encourage the youth to attempt a shorter distance and inspire them to improve their well-being through sport.

Ms Lynn Tan, general manager of OSIM Singapore said: "Being Asia's No. 1 healthy lifestyle brand, our aim is to inspire well-being in everyone from all walks of life, and we also wish to contribute to Singapore's running scene in every possible way."

Organisers expect this year's eighth edition will see up to 30,000 participants on a route that takes them along the East Coast Parkway and onto the Benjamin Sheares Bridge before the finish line at the F1 Pit Building.
