The courses for the Triathlon competition, the only one in Korea are 3.8km of swimming, 180.2km of bicycling, and 42.195km of marathon running. The marathon course goes along Jungmun Park and Jeju World Cup Stadium, makes a turn at Cheonji-dong, and returns three times to Jungmun-dong. The bicycle course, which can be completed by running around in one circle, can be hardly seen at any other international Ironman competition. The beautiful views of shoreline can be enjoyed while running along this course. Especially, when passing the mountain’s summit on the road, the complete view of Seogwipo City can be seen, and the rolling course starting from the summit is another enjoyment. It would be a wonderful opportunity to participate in the Jeju International Ironman Korea, but even if you can’t, it can still be exciting to just watch the competition. On the roads and streets where the competition is held, there are more spectators than participants who crowd around and cheer participants from all around the world every year. It’s a great time for everyone!
