Why Buy a Double Running Buggy?
double stroller with car seat running buggy is the best choice to run with your child. Traditional strollers are great for daily use. These are designed specifically for jogging and come with large wheels, air-filled tyres, and often a front wheel that locks for additional suspension.
Side-by-side models such as the Mountain twin buggy Duet and Out'n'About Nipper Sport double umbrella stroller V4 are ideal for jogging infrequently, or more hard-core runners are likely to prefer the more advanced double stroller sale-running pushchairs like the Thule Cheetah 2 bike trailer.
Safety
A double running buggy has three or four wheels (like a standard pram) but they are often larger in size, with the front wheel locking for more suspension and control. Most double running buggy handlebars feature brakes (similar to the brakes on bikes) so that you can quickly stop your buggy. Many also have wrist straps for extra safety. Some also have a slightly reclined seat to provide extra comfort while your kids are having a nap or eating. You should wait until your baby is at least nine-months-old before you go for a jog, and only when they are at ease.
