Ok, let the man himself answer to all those allegations and questions…
No, I didn’t drink 1.5l in 4miles, I drank 1.25 during the 75min of running. Yes I drink alot in the pool, on the bike, and while running. And no, that thing wasn’t empty at mile 4, in fact it still had some in it at the end, but after 4miles it felt already empty and last week when it was 85F+ in that canyon I was in big trouble at the end of the run. It was during last weeks run when the 750ml bottle was empty after 30min that I swore myself never ever f#ing ever to run in that canyon without a Camelback again. I do as I say.
And yes, I was already tired after 6hrs of riding on Wed, a Thursday AM high intensity bike session, followed by a PM run. Friday 90min easy bike. Saturday 3hrs with 1.5hrs very hard. Yes, I was tired and I’m sure that might have contributed a little to it.
But hey, if anybody is working for Cytomax and wants to sponsor me, I’m all over that product. I usually add some additional electrolytes to it though. (and to those that already think I’m adding way to much salt, no. I’m also thirsty when I consume less electrolytes). You won’t find many other triathletes that would be sipping on your product as frequently as I do.
For those that talk about sweat rate. In a lab setting, room temp 72F -74F. with two big fans blowing on me, ~47.5min TT all out, avg. 369W, NormP 375W I drank 1.5liter of water and weighed still around 1kg less at the end. Yes, some of it is weight lost besides water, but I do have a high sweat rate which is cool for short to medium Time Trial efforts but kind of sucks in the heat, especially if I’m not used to training in such an environment. It’s tough living near the beach here with year round comfortable temperatures. Don’t feel sorry for me, I think I’m gonna make it, but it’s though 
And yes, I was also a pro drinker when I was younger. seven double shots of tequilla plus some SoCom and a couple of beers made some very very bad memories, but that’s another story…
