Afterward, the couple headed down to the Kia Forum for Blink-182's performance there.

"I don't want it to be discouraging. It should be fun," Travis told PEOPLE ahead of the event.

"I feel like everyone can get out and do 5Ks. Even if they see this, and they don't run it, maybe it motivates them to get outside."

Kourtney and Travis first bonded over a shared love of exercise before they discovered their feelings for one another.

"We would always work out together and run together or do stuff like that together before we were ever in a relationship," Travis told PEOPLE.

"We were workout buddies forever."

The drummer's wellness crusade came after a 2008 plane crash, which killed four people and left him in critical condition with over 70% of his body covered in burns.
