This really should be in. I hated doing escorts because I always was much faster and had to constantly stop and wait. That annoyed the hell out of me. Running speed should of course be differente depending on attributes/skills, because you WANT to run faster than someone else, but there are hardly any reasons for you to want to WALK faster than anyone else. Instead, you want to walk at the same pace so you don't have to stop all the time and wait for people (or, if you are slower, run after them, then walk with them for a bit, then run again... Argh!)
