Packing for a Half-Ironman

My biggest dilemma for this Saturday's Oceanside 70.3 is what I'm going to pack. I'll admit it - No matter where I go, I overpack. Why would I want to be in a position where I'm unprepared? In my mind, I envision being in each moment during the race, and I pack accordingly. This is what I'm bringing with me this weekend:

General

• Headlamp - It's gonna be dark
• Tri Top, shorts, and flip flops. I'll be wearing these to the race, but I have to remember to pack them before I leave for Oside!
• Garmin Forerunner 920xt
• Heart Rate Monitor (I Forgot this at my last 70.3 and wanted to cry)
• Garmin Vivosmart HR (yes, I want to bring both Garmins - they serve different purposes outside of the nasty tans I'll get)
• Chamois butter? I don't use this but it seems like everyone else does. 

Transition Area

• Bike Pump - they're asking us to drop off our bikes the day before
• Towel to lay on ground

Nutrition for Swim:

• I usually pack a coconut water to drink before my race. I sip this and do most of my hydrating the night before. 
• Some sort of fruit - I'll eat this as I walk in to drop off my stuff. Usually an Apple or a nectarine. 
• Peanut Butter and Jelly - this is breakfast at 3am. 
• Nuun Tabs. These things are magic in my water. 

Swim

• Sunblock
• Wetsuit
• Tri-Glide
• Goggles
• Swim Cap from Ironman
• Towel
• Chapstick - I swear by Carmex
• Water Bottle to clean off feet

T1

• I eat a Clif Bar and down a salt tab before I leave. 
• I will drink water because swimming makes me thirsty. If I have enough coconut water from before I'll usually sip some of this because it hydrates me more than water does. 
• Sunblock. Lots of spraying sunblock. 

Bike

• My bike. I should definitely bring my bike. 
• Helmet
• Sunglasses
• Shoes
• Race belt
• Race Number Bib
• Bike Shoes
• Bike Socks
• Riding Cap
• Gloves
• Water Bottle for Electrolytes
• Disposable Water Bottle to trade volunteers with
• Chapstick - I swear by Carmex
• Jersey, loaded with my nutrition in the back
• Clif Bar 
• Honey Stinger Waffles (2)
• Honey Stinger Chews
• Jelly Belly Sport Beans
• Extra Nuun Tabs
• Electrolytes - SaltStick Tabs, Hammer Endurolytes to take - usually one per hour on the ride. 
• The goal is to consume about 250 calories every hour I'm on the bike. 

T2

• I will probably eat some Honey Stinger chews and drink a bit of water here. No real prep because there will be aid stops on the run. 
• Sunblock
• Double check for race belt
• Switch to running shoes
• Grab my hat!

Run

• Hat
• Sunglasses
• More sunblock
• Running Shoes
• Running Socks
• Chapstick - I swear by Carmex

Finish

• Compression Socks
• Shirt to change into

See? I did it again! I overpacked. But I'm going to be so full and so prepared. I'm really excited! Thoughts? AM I MISSING ANYTHING?!
