While using the hot-shots radar gun  and pretending to wank, the scatman recorded a velocity of 3 m/s. Therefore, multiplying this by an average wank time of 30 minutes, or 1800 seconds gives a wank-run of 5400 m. A pretty impressive wank-run compared to my premature ejaculation which gives my only a wank run of 20 metres.

The running start is a manuever where one partner steadies herself (usu. against a bed) while the other partner accelerates in the first's direction.  At the end of the second partner's path lies a dry butthole therefore speed is necessary to perform this manuever.  
Once adequate velocity is acheived, the second partner thrusts his erect penis into the anus of the first individual. Thus, the lubrication normally necessary to make this type of insertion is obviated.
Figure 1 depicts and accurate and scale representation of a running start in progress.
