Actually, electrons travel very slowly in metal -- a fraction of an inch per
second, IIRC.


But doesn't each electron just bump the next one into submission? Kind
of like a relay race?


Yes. Think of a hose filled with marbles. Push one more marble in at one
end and a marble falls out the other end almost instantaneously. The net
velocity of the individual marbles, however, is relatively low.
