depends on what you mean by well spent
for the organisers - probably - as it's a competitive event at elite level and the more elites they have running, then the bigger exposure the race will have in the media - and maybe the better the race.
for the ordinary runners doing it - probably not much difference and as long as we aren't being asked to stump up for the cost, then no big deal imho
they may also be covered by insurance for this as well
