It didn't take much of a change in atmospheric composition to completely tank my ability to go at a pace I know as well as this needs. | |

I might be more tired but I will not be walking slower unless the gravity or oxygen level is significantly different, in which case, again, I'll know. But at those levels, that would also affect your entire body at rest, so none of the other answers would work either. | |
