The 25-year-old clocked 1:21:13.60sec to finish behind China's Wang Zhaozhao (1:20:36.90) and Japan's Kento Yoshikawa (1:20:44.90), for a podium finish in the tournament's first event. Sebastian's timing was just shy of his personal best of 1:21:23sec, set earlier this year for a gold at the Uttarakhand National Games in February.
