The second edition is scheduled three months earlier than last year, just several weeks after the easing of social distancing regulations.
Athletes will compete in a 1.5km swim, 40km bike and 10km run in the afternoon to sunset, a unique time compared to other triathlons in Vietnam.
Last year, more than 300 athletes from 18 nations and territories took part in the event.
