Yeah, I figured that out looking through the PHB and DMG. And it does make sense that you can just run flat out. That's what we did with Akos. I probably should have had you roll a couple of Balance checks to keep from running into hedges or fences. Heh. No worries.In the city, distance is whatever the closest corner is That's how far you can see
As for halving - it represents careful movement, you cannot prevent anyone from just running full out and trusting in his luck not to hit something (or being heavily armored, not caring about hitting something) - normal streets are usually passably passable
