Do you plan to have 1 or 2 people supporting you? Just have your support leap-frog ahead of you by about 30 minutes (say 10 miles)...(BTW, first support is a fair bit out of town, I'd have to check but it might be on the order of 45-50km which might be the only time you'd want all 3 bottles unless it is a really hot day). If you take liquid nutrition, have your "liquid food" in one color bottle, and water in the the other. That way when you are biking up to your support person, you can hold up whatever color bottle you need and be seen at a distance. That way you can drop the bottle in front of your support and they can hand up the full one as you bike by. If you need more stuff, then just stop at the back of the car and load up...it only takes 15-20 seconds.

For the run, have them leap-frog ahead every 2-3 miles or whatever interval you like to see on a supported race. Every mile is hard, so practice a handoff every 20-30 run minutes.

I'd recommend you go out on a long weekend ride and practice 1-2x before the race to work out your system and calm everyone's nerves. Prepped food in the cooler, or easily mixed food at the ready is always helpful. Also, have your support practice putting the bike on the auto bike-rack/in the car at T2.


EDIT: if you get the timing right, have the crew mix up the liquid nutrition after you have a bottle handup but before they drive to the next stop. That will let you get a bit ahead of the support car. This is nice as it can limit the time you might be at the side of the road with a bike breakdown. Get a bit ahead (5-10 minutes), then the support car will drive by -- give a "thumbs up" if all is well, and if you don't show up within 15 minutes of the next handoff then the crew can decide that maybe you've had a bike breakdown and they can circle back on the route to find you and your mechanical issue.
