These are IMO the best products out there in their respective fields:
Ultima: doesnt taste that great, and i originally thought it would be horrible on a run (when my stomach is the most sensitive), but it was awesome. I was well hydrated, my stomach had no discomfort (which i used to have with gatorade and accelerade), and i had very even energy levels, rather than the rise and fall i usually have.
Optygen: i noticed my HR dropped 10 beats when running at the same pace within a week, and a huge drop in perceived exertion. I also noticed the effects seem to “wear off”, maybe i just started running faster till my pace matched my “new ability”.
accelerade gel: i love accelerade, but it gave me the squirts. For some reason, the gel doesnt bother me, and gives me tons of energy.
camelbak: hands-free hydration. that about sums it up, also, no chaffing.
giro atmos: super-cool, both temp wise and fashion wise
Orca Elite wear: Ti3 kicks so much incredible ass, you have to use it to understand it.
shimano tri shoe: no socks, no chaffing, super stiff carbon sole, very vented, the newer ones are even more vented. also, the huge strap makes it easy to put on in T1.
endurox: great recovery drink, ive noticed much faster recovery times.
