Celina and Elmo are going running in the park, but Celina tells him they have to wait for her surprise friend - Buster the Horse! Neither of them have gone running with a horse before and are very interested in how it will work...
Buster arrives for their run, but first, Celina says they have to stretch first (which Elmo and Buster don't normally do). They then do some warm-up exercises and Buster even convinces them to whinny before they start running.
Celina stops everyone from running for a quick count-to-20 break.
Buster, Elmo and Celina illustrate "J" for "jog."
Everyone stops running in where Buster considers to be the best place in the park. Elmo believes it's because of the pretty flowers and Celina thinks it's too enjoy the sounds of the birds. But, Buster likes the spot because it has nice grass to feed on.
