Why Buy a Double Running Buggy?
Double-running strollers are the ideal option for running with your child. Traditional strollers are great for everyday use. They are specifically designed for jogging and come with large wheels, air-filled tyres, and often a front wheel that locks for additional suspension.
For occasional jogging, models like the Mountain Buggy Duet or Out'n'About Nipper Sport Double V4 will do. For double pushchair who are serious about running, they might prefer the double-running pushchairs like Thule's Thule Cheetah 2.

Safety
Double running buggys are equipped with three or four wheels, similar to a pram. However they're usually bigger and the front wheel is locked for extra control and suspension. double pram and pushchair of double running buggy handles have brakes (similar to those found on bikes) so that you can quickly stop your buggy. double pram pushchair have wrist straps for added security. Some have a slightly reclined seat that provides extra comfort for your child while they are eating or taking a nap. Be aware that babies must be at minimum nine months old before running with them in a stroller and only if they're comfortable in it for long periods of time.
