Why Buy a Double Running Buggy?
Traditional strollers are great for daily use, but if you want to go running with your kids, then you'll require a double-running buggy. These are specially designed for jogging and come with large wheels, air-filled tires, and often a front-locking wheel to add suspension.
For occasional jogging models such as the Mountain Buggy Duet or Out'n'About Nipper Sport Double V4 will work. Hard-core runners may prefer the double pushchairs for running, like the Thule cheetah 2.
Safety

A double running buggy has three or four wheels (like a standard pram) but they are typically larger in size, and have the front wheel locking for added suspension and control. The majority of double running buggy handlebars feature brakes (similar to those on bikes) to enable you to quickly stop your buggy. Many also have wrist straps to ensure security. There are also how you can help that have a slightly reclined seat to provide extra comfort while your kids are having a nap or eating. Remember that babies should be at least nine months old before jogging with them in a stroller, and only when they're comfortable for long durations of time.
