bike during HIM
I would think it's not the most ideal solution, but I did see people in my first HIM do it. I would think that if you're trying to be in your aerobars for that long, having something on your back would be both tiring, annoying and inefficient. I raced mine with two 26oz bottles in my cage frame and a aerodrink bottle and was fine with the amount of liquid I had; plus they usually have bottle exchanges for that distance.
Have you ridden with it in training?
I tried using one on a long ride - hated it - nasty chaffing.
Really no need for one in a HIM. You should be able to carry 2-3 bottles on the bike and with the bottle exchange getting more fluid not an issue. Unless you have a reason that you can't drink what is being offered, then maybe that is the way to go. Tho I will train with whatever is going to be on course to make sure there are no issues. Why do you want to use one?

There is three reasons I did not use one. The first is weight, any weight while in the aero bars just sucks. The second is water exchange you just can't do it with a camelbak. The third and least consequencial reason is being aero it self... I just had two bottles in the seat mounted cages I had and was good to go for my half. If you are picky about your type of drink, get the powdered version and keep a vial or two of the powder in a tool pack or pocket or something and mix your own on the exchanges...
You could use one but I don't think you would need to. They should have plenty of aid stations with water and gatorade (or whatever the use).
If you have 2 water bottles with fluid and then the aid stations then you should be fine. What usually happens is you give up your water bottle at the aid station, throw it to the side and get a new one. So, when you go to the race, bring some old water bottles, not your favorite one or most expensive one. Most races give you a water bottle, use that.
Another thing to look at is an aero-bar water bottle if you have aero bars. That stays on your bike and you don't have to fiddle with getting the water bottle out and back into the carrier. At the aid station, you get the fluid and just dump it into the water bottle.
I might use a camelback when training if the roads I bike on don't have too many places to stop to buy additional fluids.

I wear one for adventure racing (mtn biking and trekking sections). They work fine -- it's easy to get water, etc. However, in aerobars the weight is a bit less comfortable.
I agree that an aerobottle can be great -- just as easy to reach without the weight on your back and shoulders.



Has anyone used a CamelBack on the bike during a Half Ironman? Im planing on using that on mine, but I will take it off in t2 so i don't use it on the run.
Now i know everyone is gonna say..."do what works"...im just seeing what you all have done.
thanks
If you get a flat, and don't have a tube, Suck it up and run it in!!!
