Why Buy a Double Running Buggy?
Double-running strollers are the best option to run with your child. Traditional strollers are suitable for everyday use. These are specifically designed for jogging and come with large wheels, air-filled tires and often a front-locking wheel to give suspension.
For jogging infrequently best double stroller as the Mountain Buggy Duet or Out'n'About Nipper Sport Double V4 will work. Hard-core runners may prefer the double-running pushchairs such as the Thule Cheetah 2.

Safety
Double running buggys are equipped with three or four wheels, similar to a pram. However, they are usually larger and the front wheel is locked to provide additional control and suspension. The handlebar will usually have brakes (similar to on bicycles) to stop your buggy swiftly and all have a wrist strap to provide extra security. You'll also find some have a slightly reclined seating for added comfort when your children are napping or eating. Keep in mind that babies should be at minimum nine months old before you can begin running in a buggy and only when they're comfortable for extended durations of time.
