For serious runners, this stroller is a must. It is light weight and very easy to push. Kids ride comfortably from 6weeks to 6years. The 20" wheels are best for runners. Downside - doesn't recline, but kids don't seem to mind and still fall asleep. I recommend getting a weather shield to protect from rain and snow if you are going to run outside in cooler weather. The shield will keep kids warm in all kinds of weather. I ran everyday of the year with my 2 kids and 2 dogs along side in Colorado. I would buy this stroller again and again.
