This will most likely be gotten through natural progression but if you're wanting to smash it out an easy level to do it in is 'Hypocenter'. During the level, you'll start making your way down a long cylindrical area. At the bottom of this area you'll fight some robots. After this fight, just wall run around the edges until the achievement pops
Edit: Make sure you have the 'Traversal Enhancement' tactical rig equipped, otherwise you wont be able to wall run.
