Why Buy a Double Running Buggy?
Traditional strollers are ideal for everyday use, but if you would like to run with your kids, then you'll require a double-running buggy. cheap double pushchair are designed specifically for jogging and feature large wheels, air-filled tires and often a front lockable wheel to add suspension.

For jogging infrequently, models like the Mountain Buggy Duet or Out'n'About Nipper Sport Double V4 will do. Hard-core runners may 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. The handlebars will typically have a brake (similar to bicycles) so you can stop your buggy quickly and come with a strap for your wrist for added safety. Some have a slightly reclined seat to provide additional comfort for your child when they eat or take a nap. Be aware that babies must be at least nine months old before you can begin jogging in a buggy, and only if they're comfortable in it for long periods of time.
