A colleague used to enter the race, organised,I think, by a national paper. He won the motorbike section one year, on an old BMW flat twin, but the resulting product wasn't up to much. It varied a good deal from year to year and producer to producer; some years it was passable, suitably chilled; but in general the whole thing seemed an overblown publicity stunt. Restaurants local to me in London used to play along with this and advertise its arrival, but I haven't seen that in over 20 years.
