Also, with regard to carrying spare stuff, plenty of people do that (I'd say usually over half). It's really up to you, though I recommend that you carry spare stuff, seeing as how flatting and DNFing is usually far worse than flatting and taking 5 minutes to change the tire!
+1 on the repair stuff
I would much rather carry the extra pound or two and be able to change my tire 6 miles out from the transition area than be walking my bike back and having to DNF, especially with the prices of Tris nowdays.
That said I did double flat in an off road event and ended up foregoing the run but still able to roll in with a borrowed tube from a fellow racer.
And I think I have borrowed my pump out at least twice in off-road events to folks trying to save a few pounds by not carrying one. Old days before CO2 cam einto vogue.
