0:00 Hey people, welcome to the run testers and to our review of the new Puma Fast R Nitro Elite 3 that we will be calling the Fast R3 from here on in. This is a shoe that's been making a lot of headlines thanks to some Nike 4% style research that suggests this shoe is now the most efficient carbon racer you can buy right now. Now, results from the lab are one thing, but how does this shoe perform out in the wild on the road? Well, myself and Nick have been smashing out some fast and hurty miles in the new Fast R3, including racing the London Marathon to find out exactly that. Let's get into it in our Puma Fastar Nitro

0:31 Elite review. Quick details first then. The Puma lists the stack height of this at 40 mls in the hill, 32 ms on the fore foot for an 8 mil drop. Weight is one of the big headlines here with a big chunk saved off the Fast R2. More than 30% cut from the shoe. In fact, so the Fast R3 now weighs in at 6.2 oz or 175 grams in my UK men's 8 and a half test shoe. Slightly heavier than the new Vapor Fly 4, but lighter than the Meta Speed Sky Paris. On price, it's launching at $300
