Why Buy a Double Running Buggy?
Double running buggy is the best choice to run with your child. Traditional strollers are suitable for everyday use. These are designed specifically for jogging, and feature large wheels, air-filled tyres and usually the front wheel locks for additional suspension.
For jogging on the occasional basis models such as the Mountain Buggy Duet or Out'n'About Nipper Sport Double V4 will work. For double buggy with carrycot who are serious about running, they might prefer the double pushchairs for running, like the Thule Cheetah 2.

Safety
A double running buggy has three or four wheels (like a normal pram) but they are typically larger, with the front wheel locking for added control and suspension. Most double running buggy handlebars come with brakes (similar to those on bikes) to allow you to quickly stop your buggy. They also come with wrist straps to ensure security. Some models have a slightly reclined seat to provide additional comfort for your child while they are eating or taking nap. Remember that twin buggy from birth should be at minimum nine months old before you start jogging with them in a buggy, and only if they're comfortable in it for long periods of time.
