Did you find the volunteers swamped?
I've done very low key running events where there is barely any support, but for the cost of the triathlon there should be some.

1) Was there enough food and drink at the Florida event? Will I be able to refill a bottle, for instance?

2) Were there enough portapotties?

I did a triathlon last year where I had to compete with spectators for one of 2 stalls to take a leak.
My finish time was 55 seconds off my target ... so it was pretty annoying in retrospect that I could have hit that if I didn't have to wait..
