Terrex Agravic Speed 2 vs Catamount 3

The Terrex Agravic Speed is adidas at its most stripped back on the trail: a lightweight trail racing shoe built to move fast over shorter, sharper terrain. At 240g it sits firmly in the fast-and-low camp, and there is no carbon plate here, so what you get is a direct, ground-feel-forward ride rather than a propulsive rocker. That is the point. This is a running shoe for runners who want to feel the trail and react to it, not float above it. The 8mm drop keeps you in a familiar, slightly heel-biased position that most road converts will get on with straight away. We rate it as a proper trail race and tempo tool: skyrunning, shorter ultras, hard hill efforts and race-day on technical ground. If you want more shoe underfoot for long days, the roomier Terrex Agravic Speed Ultra is the natural step up. For fast trail work, this one earns its keep.

The Brooks Catamount 3 is a lightweight trail running shoe built to be raced, not just run. At 269g with a 6mm drop, it sits at the fast end of Brooks' trail range: a nimble, propulsive shoe for runners who want to hold a hard effort over technical ground. This is not a plush ultra cruiser and it is not a rugged tank. It is a trail racer, tuned for tempo efforts, short-to-medium trail races and fast days on rolling singletrack. You get an energetic, connected ride that rewards a quick cadence, with enough underfoot protection to keep the sharp stuff at bay without deadening the trail. It is a neutral shoe at a race-day price, so it asks something of your legs and your wallet. In our view the Catamount 3 earns its keep if you actually race trails or push the pace on them. If you mostly plod easy miles, a softer, cheaper daily trail shoe will serve you better. As a fast trail shoe, we rate it highly.
