The Pokemon Summer Academy is almost over, but there's one more event left: the Pokemon Triathlon! Each Trainer will use two random Pokemon to race to a nearby lake and cross, then run on foot back to the Academy. Ash's Red Team is currently last in the overall points, but each Red Team member's points in this event will be added to the total score. So the race begins and the campers take off, led by Ash on a Spoink and Dawn on Dodrio. However, Angie has her Ariados sling some webs to swing her into first place. Once they reach the lake, Angie gets a Lapras, Ash gets a Mantyke and the two remain ahead of the pack.
Jessie is dead last until a speedy Magikarp helps her move up several places. Conway decides to follow her, but Jessie thinks he's so creepy that she runs like the wind to get away from him. She even speeds past Ash and Angie, but Conway won't give up--so she has Seviper use Poison Tail to drive off Conway.
Battling is against the Triathlon rules, but before Ash and Angie can protest, Seviper's Poison Tail knocks Angie and her Shinx into a pit! By the time Ash pulls Angie to safety, Jessie and Conway are long gone.
However, Jessie and Conway are exhausted by the time they reach the Academy. Ash and Angie easily pass them and Ash just manages to beat Angie to the finish line. Once everyone is done and the points are totaled, the Red Team has come from behind to win the overall award! Everyone celebrates the final night of camp with a bonfire and Ash promises to visit Angie in Solaceon Town. But first things first: the next morning, he and his friends are off to Celestic Town for a Pokemon Contest!
- During the bonfire, While James told Meowth that they forgot why did they come to the summer academy in the first place, In the background we see the other teachers carrying all of the pokeballs contain all of the pokemon from the academy, This is a refernce to DP088 in which their plans was to steal of the academys pokemon and give them to the boss.
