The second edition of The Straits Times Run at the Hub on Sept 27 will again see runners finish under the iconic dome of the National Stadium, where they can take part in an energetic post-race activity.

At the stadium, three instructors from True Fitness will captivate the participants with a Sh'bam performance. Sh'bam is a workout which features energetic dance moves performed to the music of the latest chart-topping hits and dance tracks.

Race-goers can join in the exercise which instructors promise will be a fun workout.

Said True Fitness instructor Celina Low, 45: "A Sh'bam performance features simple but interesting dance moves and is a fun way to exercise and socialise.

"You can expect to improve your coordination skills and increase your cardiovascular fitness."

The True Fitness instructors will also lead warm-up sessions to help runners limber up before each of the three categories - 18.45km, 10km and 5km - flags off.

The 18.45km category, which replaces the half marathon, is a new feature of this year's ST Run.

It commemorates the paper's 170th birthday.

The national daily broadsheet was established in 1845.

This year, all runners who complete their respective events will receive a medal.

Previously, only finishers in the half marathon got a medal.

This is also the third instalment of the ST Run which is backed by electronics giant Panasonic for the third consecutive year.

The first edition in 2013, which was held at the Punggol Waterway Park, drew 12,000 participants.

Last year's ST Run at the Hub attracted more than 21,000.
