Notes: The speed of a Metro bus was found by taking the average time of the 2 along its route from Dodger Stadium to Pacific Coast Highway on a Sunday morning and applying that to the length of a marathon. It's expected that the presence of 26,000 runners will slow it down somewhat. Bear times are based on their top running speed over a few miles. BB-8's time was determined by Rhett Allain for Wired. The airspeed velocity for an unladen swallow was obtained from Wolfram Alpha. Animal times may vary.
