Why Buy a Double Running Buggy?
Traditional strollers are great for everyday use, but if you would like to run with your children, then you'll need a double-running buggy. They're specifically designed for jogging, and come with large wheels, air-filled tyres and often a front wheel that locks for additional suspension.
For jogging on double stroller , models like the Mountain Buggy Duet or Out'n'About Nipper Sport Double V4 will perform. Hard-core runners may prefer the double-running pushchairs like the Thule Cheetah 2.

Safety
Double running buggys have three or four wheels, similar to a pram. However they're usually bigger and the front wheel is locked for extra control and suspension. The majority of double running buggy handles come with brakes (similar to those found on bikes) so that you can quickly stop your buggy. They also come with wrist straps for extra security. You'll also find some have a slightly reclined seating to provide extra comfort when your little ones are napping or eating. Keep in this link that babies should be at minimum nine months old before jogging with them in a stroller, and only when they're comfortable for long durations of time.
