In July, Jinusean's Sean promised Eunchong that he would complete the triathlon for him.

Eunchong is a 10 year old boy who is suffering from 6 rare diseases. Sean has supported Eunchong many times in the past, attending sports events with him and running in races together. Back in July, he tweeted, "For Eunchong, for athlete Park Seung Il and for those suffering from Lou Gehrig's disease, I'm going to try my hand at the triathlon."

He trained for the triathlon for three months, and finally completed the event on October 19th in 3 hours and 2 minutes. He tweeted, "1.5 km swimming, 40 km cycling, and 10 km running. I completed the triathlon in 3 hours and 2 minutes. I kept my promise with Eunchong. And.... the promise I made with myself to donate 1000 KRW (approximately 0.91 USD) per 1m. I will be donating a total of 51.5 million KRW (approximately 47,000 USD) to build a children's rehabilitation center."



He also uploaded the above photo of himself with the Iron Man mask, writing, "Mission accomplished. I am the IRONMAN!" Check out footage of the event below


 
Congratulations Sean for keeping his promise and becoming a tri-athlete!
