Now there's a challenge, drive a marathon route, stopping at every possible boozer and drinking 1 standard measure drink, before driving to the next. Chances are, by the end you'll be too drunk to drive (ignoring any legal nuisances you'd have broken by the second pub). Clearly getting a taxi would remove a large part of the challenge, as it would just amount to speed drinking.
I wish that I lived close by as I'd come down to the roadside and accidently trip you up as you ran by, just enough mind to cause slight damage your calf muscle. Then, being the honourable chap that I am, offer to help you to the line. Of course with my support the line would be crossed at eaxctly 2:14:22.
