Terrex Agravic Speed 2 vs Peregrine 16

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 Peregrine 16 is Saucony's do-everything trail running shoe, and the version most people should start with if they want one pair for the trails. It is an aggressive all-rounder built for grip first: a full Vibram Megagrip outsole with deep lugs that bites into wet rock, mud and loose gravel with real confidence. With a 4mm drop and a moderate 32mm heel stack it sits between a nimble racer and a plush max-cushion trail shoe, so it stays quick and connected to the ground without beating up your legs on longer efforts. Saucony has made this one softer and grippier than the Peregrine 15, which nudges it toward comfort over a wider range of distances. In our view it is the natural rival to the Hoka Speedgoat and Brooks Cascadia at this price. If you run mixed, muddy UK trails and want a dependable shoe that handles almost anything, this is an easy shoe to recommend.
