Race Day: What goes in the water bottle?

I typically only put water in the aerobottles because it's too messy with sports drink if it splashes out.

For a sprint, I usually take one bottle of Nuun on the bike.  Wouldn't have a chance to drink more than that on the bike. 

Water is for the flowers... 

I looked back at my pace graph.  I was thinking I averaged around 20 kph, that is where the 90 minutes came from (30K bike leg).  Lately the average pace has actually been between 22 and 25 kph.  So it isn't 90 minutes, but is is still over an hour for 30 K.

I could push it, but the run is the hardest part for me, so I want a little left in the tank.

x2 on the advice to stick with what has worked in training an DO NOT try something new on race day. 

The first time I ever tried Accelerade was at a race and I chugged some on the bike. Besides the fact that it was the most vile-tasting crap I've ever had past my lips, I cramped up and had to walk-run the 5k.

I like to use gels and Power Quencher, which is an electrolyte-only sports drink; no carbs or calories and tastes better than the Gatorade-type drinks. I'm an extremely heavy sweater so it's great for me. Also, because it has no sugars, it doesn't make the bike all sticky when it sloshes or drips.

For a sprint?  There's no need.

Put water in your water bottle.  You have plenty of blood glucose and stored glycogen to get through a sprint.  If you don't buy that idea, put whatever sports drink you want in it.

Thanks to everyone for the feedback.

I think I'll just go with water.

Isn't that product an electrolyte replacement only? I don't think it has any carbs/sugars in it. Even for a sprint I take in lytes because of my sweat rate.

You could sweat gallons, and that wouldn't be an issue in a sprint.  Replace them when the race is over if you're worried about it.  Putting extra stuff in your stomach when you're red-lining it just doesn't seem prudent.
