Participants warming down at Suntec City's True Fitness after yesterday's 5km training run in preparation for July 16's ST Run 2017.
The programme had included a complimentary KpopX fitness session organised by True Fitness but it was cancelled because the instructor had a family emergency.
The workout was still useful, said sales coordinator Cheah Shu Lin, 31, who will be a pacer for the 18.45km race.
She said: "The participants may not run regularly, so these runs are a good build up. They will feel motivation too while running in groups."
