I have 7, 7 and 8 on the 3 toons I play the most. However I truly truly regret it as it seems to be worthless. In my light weight loadout (tribal warrior, leather boots, wisby guantlets, klappvisor) Goretooth in his heavy black armor shit and Cyranule both keep up with me, and they're str builds (Cyran said he has 12 agi, so 4 athletics at the most). I should be outrunning them by a fair margin, instead they can keep up with movement speed no problem. So I've decided I'm going to stop wasting points on what appears to be a semi-useless skill.
