On KBS2's "The Men Who Live to Work Season 2" (hereinafter "Salimnam"), Park Seo-jin, Ahn Sung-hoon, Shin Seung-tae, and Jae-ha take on the challenge of a half marathon. "Marathon hero" Hwang Young-jo appeared on site in person to help the four complete the race.

In the previous episode, the four were shown completing a 10km marathon at Yeouido Park before taking on the half marathon challenge.

Before the start of the race, Hwang Young-jo, Park Seo-jin's running mentor, appeared while they were warming up and delivered a message of encouragement. Hwang Young-jo guided them through injury-prevention stretches and then ran the first 3km section himself, acting as a pacer. He emphasized, "Don't think about your record; run safely."

Once the race began, Hwang Young-jo ran alongside the four, checking their condition. When they seemed to be picking up their pace under the influence of other participants, he advised, "Don't get swept up in the competitive atmosphere. Don't get excited; stay relaxed." On an uphill section, he also praised Park Seo-jin for keeping his stride short while running, following his guidance.

At the 3km mark, Hwang Young-jo left the group, saying, "Keep focusing on controlling your pace until the end, and walk if it gets too hard." He then moved to the later section of the race to check the four runners' physical condition and offer additional advice. Hwang Young-jo assessed that Park Seo-jin's running ability had greatly improved in just five months, and he encouraged the four to continue the race at a pace suited to their individual conditions.

The story of Park Seo-jin, Ahn Sung-hoon, Shin Seung-tae, and Jae-ha's half marathon challenge will air in episode 479 of KBS2's "Salimnam." Meanwhile, the episode of "Salimnam" broadcast on the 17th recorded a peak viewership rating of 4.8% nationwide, according to Nielsen Korea.
