This is a great resource that can be used in all three races. It’s drying quality is one of its best properties, and can be used after the swim, to quickly dry the body. For instance when putting on foot gear after the swim, you can use it to instantly dry the feet.

During the biking event, having your shoes already set on the bike allows for a quicker transition. Use a rubber band to hold your shoe onto the bike (from the area above the chain), and the band will easily break on the first rotation.

Using baby oil can help with chafing, but it is also an excellent way to to help with the removal of a wetsuit, which tends to stick to the body.

For your biking shoes, having elastic laces allows for you to slip them on easier (which are mounted on your bike). Make sure you know exactly how the laces need to be and use a lace lock, or no-tie laces. Otherwise might end up at the aid stations for a shoe tie.

A pair of golf balls can fill in for massaging devices. They are small and light. Some use tennis balls, but their texture easily snags and causes a jarring glide.

Empty water bottles are a great way to keep things dry like shammys and small towels. Even things like keys and gels held in a bottle is easier to fit in a bag, and of course keep dampness away.

A swim leash can create an endless pool when you are staying at a spot without a proper place to train and warm up. It only slightly affects one’s’ stroke, but not as much as you’d think.

Roman soldiers used to train with heavier weapons and shields. They would also train in melee longer than they would before the next rank would take their place so they could rest. 

When transitioning from the wetsuit, the best top to change into is one with a zipper. Covering your upper body in baby powder isn’t the most efficient method. So a full zip, or at least 8-inch zipper is highly recommended.
