Around 6h, artist Truong Giang arrived at the starting area. He continuously energized the atmosphere with engaging exchanges, humor, and interaction. Many children were excited to meet their idol in person, asked for photos, and warmed up together before the race.

In addition to artist Truong Giang, Kun Marathon Can Tho 2026 also featured many young KOLs popular with children, such as: child actors Hao Khang and Candy Khanh Dan, YouTubers Kairon, SinL, and Be Si. Before the race, the KOLs conveyed messages about animal and environmental protection to the children as part of the event's overall message.

Accompanying the 6-year-old group in the first starting wave, Truong Giang continuously moved, holding hands to support the children in overcoming challenges. At the "Colorful Swamp" obstacle, when many children slipped or lost their shoes, the artist enthusiastically returned to help them.

Kairon supported young runners in completing the racecourse at Kun Marathon Can Tho 2026. Real name Nguyen Thanh Quoc (born in 2003), Kairon is a familiar face to the community who enjoys Minecraft and Mini World in Vietnam. The streamer is known by many children for his entertainment content, open-world exploration, and creative building on gaming platforms, attracting a large following on social media.

Hao Khang picked up a shoe for a young runner. He is familiar to young audiences through his roles in sitcoms like "Vu dieu mua xuan" (Spring Dance) and "Hoa son tra" (Camellia), and is widely known for his role as An in the film "Dat rung Phuong Nam" (Southern Forest Land).

The racecourse, nearly 1 km long, was vibrantly designed with a series of obstacles such as: ball pits, inflatable houses, climbing walls, and crawl tunnels, creating an engaging physical activity space. Many parents expressed hope that the event would be organized nationwide, creating more opportunities for children to exercise and interact.
