I don't think the sports-fest counted towards the Kingdom performance part of the show. I'm fairly sure it was on its own, just a fun day for them all.
Bang Chan - he's super athletic and very competitive! I had heard this was his first time ever doing the vault jump and to see how well he did for it - just wow! So good. I did find it amusing that they were all thinking the tall idols would do so well, but it's not about your own height. Bang Chan and Minhyuk are definitely not the tallest, but they did so well.
For the catch the tail game - ya only the head was allowed to go after the balloon. Wooyoung was soooo smart though in the 3rd set. He attached himself to the player on the other team so they couldn't reconnect, causing the other team to lose because they were disconnected for more than 10 seconds. Very impressed with how smart he played that! And of course, Bang Chan as the tail - very impressive again. He was aware of how close Eric was to him and was able to move. He did apologize for the cardigan as I don't think the cardigan survived lol.
Relay race - it's too bad Eunkwang fell down during the handoff to Minhyuk for the last section. I was super happy to see the oldest group doing so well. Bang Chan has done races before during the idol olympics and he's always pretty fast in that so I wasn't as surprised to see him just go all out and catch up so fast. I do wish Changbin had run - I have long heard from other Stays that he is pretty fast as well. I think the only time I've seen him run is during MVs like Hellevator and My Pace. Though he did run full out along with the others during the MAMA 2022 Venom/Maniac. I need more of Changbin running ;) lol
