So my personal best today was 153 centimetres (the handy reverse side of the tape measure tells me this is just over 60 inches). This is only when the tape measure is at an upright angle, low ceilings permitting. Sideways, it's nowhere near eight feet, sorry to say.
I may possibly have imagined I was in an olympic stadium at one point, smugly watching my opponents crumble at the crucial 131 centimetre stage.
