INFINIT - Keep It Simple On The Bike
I have personally used INFINIT for 4 Ironmans and having a product that I have tried and tested allows me to take confidence into my racing.
I have detailed some of my actual experiences so you can learn from me and optimize your plan for your next big race or challenge.
I take all my calories on the bike from INFINIT, this ensures the osmolality (concentration) in my stomach is suitable for easy absorption across my small intestine, no inference with salt or calories from other sources.
I aim to consume 281 calories per hour on the bike on the bike, but I tailor my formulas to suit the different climates I race in. Kona will be very different to racing a temperate race.

Two Approaches To Consider
Superconcentrate Mix 6 scoops of your blend into each INFINIT Bottle. Take two on the bike. Each bottles supplies me with enough calories for 3 hours. During the Bike take in about 1/9 of the bottle every 20 minutes and follow with water immediately.
Notes: Using this method relies upon chasing your INFINIT with clear water after every drink, this will get it back to the intended concentration, so it can be readily absorbed and you stay adequately hydrated. Make certain you take the time to calculate how much water you will be taking in if you are sipping on an aero-bottle straw. I use this method in all my Ironman Racing to calculate your sweat rate I recommend you do a sweat test a couple times during your training season to see what your water loss is per hr for different conditions (hot and cool).
Pros/Cons: Minimal weight for the bike on hilly courses. Easy to take in 1800+ calories on bike. No stop at special needs. If chase amount of water is not calculated/practiced, dehydration can result.

Normal Concentrate - Prepare 4 bottles at normal concentrate (2-Scoops each) for start of bike. Place 3 bottles on bike and empty one into aero-bottle prior to starting race. Prepare 3 bottles at normal concentration and one at double concentration for special needs. Place bottles in ziploc bags with frozen water bottles. Notes: Using this method is simple and requires no thought while on course. I would suggest supplementing this with water as well, say between 200 -300 ml of clear water every hour.
Pros/Cons: Safe, no thinking required on course. Easy to take in 2000+ calories on bike. Requires stop at special needs (30 seconds if done right). Extra weight on hilly course.
Both of the above methods are great ways of setting yourself up for a great run! Both need to be practiced. Remember the number of calories is athlete specific; you may not need 8 servings, only race on what you have practiced in training. This advice was given to me and I recommend this to any Ironman athlete: Conserve your energy and fuel your body the best you can through the swim, the bike and the first half marathon, to allow for your best possible last 13.1 miles.
I prefer formulas with a weaker flavour this means that even when I mix my drinks super concentrated they still taste good. Drinks don't need to have a strong flavour to still have all your calories and electrolytes.

So there you have it, nutrition really is the key to racing successfully at longer distances. This weekend I'm taking on the Danes in their National Championships.... in Jeulsminde . I feel in good shape and will be a good test of my fitness prior to Ironman Wisconsin next month...
