Why Buy a Double Running Buggy?
Double running buggy is the best choice for running with your child. Traditional strollers work well for everyday use. double pram and pushchair are specifically designed for jogging and feature large wheels, air-filled tires, and often a front lockable wheel that can give suspension.
For jogging infrequently models such as the Mountain Buggy Duet or Out'n'About Nipper Sport Double V4 will perform. For those 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, much like a pram. However they tend to be larger and the front wheel is locked to provide extra control and suspension. Most double running buggy handlebars have brakes (similar to those on bikes) so that you can quickly stop your buggy. They also come with wrist straps to ensure security. Some have a slightly reclining seat to provide additional comfort for your child while they are eating or taking a nap. Keep in mind that babies should be at least nine months old before you can begin jogging with them in a stroller, and only when they're comfortable for long periods of time.
