It was a star-studded affair at the launch of the Osim Sundown Marathon 2015 over the past weekend at Vivocity, as top national runners Mok Ying Rong, Mok Ying Ren, Colin Tung and Marcus Ong together with celebrity chef Emmanuel Stroobant lent their support to this year's Sundown Marathon roadshow.

The Sundown Marathon has been held annually for eight years, but this is the first time the healthy lifestyle brand Osim has signed up as title sponsor.

The launch also introduced a new 5-kilometre Fun Run category, adding on to the existing 10km, 21km and 42km categories. This new category is eligible to anyone above six.

Participants of the roadshow were treated to a myriad of activities. Starting with a lead up 5km run, participants could then attend running clinics conducted by national runners Mok Ying Rong and Colin Tung as well as a workshop on race nutrition by celebrity chef Emmanuel Stroobant.

This year's Osim Sundown Marathon will be held on July 4 at the Formula One Pit Building.
