The 2nd Sium Sium Han River Triathlon Festival kicks off on May 30 at Ttukseom Hangang Park, offering three days of light-hearted athletic fun for all ages.
From May 30 to June 1, participants can leisurely complete a triathlon — swimming, biking, and running — at their own pace and style, with 15km beginner and 31km advanced courses available.
This year, the festival expands its offerings with a massive water slide, Han River jump photo zones, and watersports experiences like kayaking and yachting.
Fitness sessions, cultural performances, and a health zone with personalized checkups also add to the excitement.
Over 1,000 safety personnel and convenience facilities like changing rooms and showers will support attendees throughout.
Open to all, the event promotes enjoyment over competition and expects large turnouts—including appearances from celebrity guests and athletes. Entry details and updates are available at sium-sium.com.
