There isn’t a magical age that indicates when it’s safe for your little one to graduate to the stroller seat. The switch from infant seat or carriage mode to the stroller seat depends more on size and developmental stage than anything else. Because their muscles are still developing, your little one needs to ride fully reclined for those first few months.
We recommend switching to the stroller seat in a reclined position once baby can support their head on their own, which is typically about three months old. Then, you can switch to fully upright in the stroller seat when baby can sit up on their own, typically between five and seven months.

We recommend that you speak with your pediatrician before starting this activity. Every baby is different, but typically a doctor will recommend that a baby be 6 months old before you jog on smooth pavement, and 12 months old before jogging on trails, grass, gravel or uneven terrain.
I interpret the last sentence as "baby w/o car seat to ride on a jogger stroller be 6 month old at minimum".
