That sounds like fun, Deborajen!

My dog's not up to running in his old age, so I've thought of doing our local humane society's event with one of my cats in a mesh backpack. Don't think the cat would enjoy it, tho. But the panicked claws digging into my back might bring on some extra speed!

And I'm impressed that a dog did a 5k in 20 minutes. Heck, I'm impressed by humans who can do a 5k in 20 minutes...
