Sprint/Olympic Triathlon Race Equipment Checklist - A minimalist approach

Some of the essentials

• trisuit
• wetsuit
• goggles
• lubricant for wetsuit
• bike with spare tubes, pump and bottle
• helmet
• bike bottle (filled with water or sports drink for +2 hrs)
• bike shoes
• race belt
• towel
• running shoes (with elastic laces)
• baby powder (for inside of shoes)
• sunglasses (optional)
• visor (optional)
• watch or GPS (optional)
• floor bike pump (or you can usually borrow one)

I could probably make a list three times as long with the unnecessary crap people bring to races, and even race with, but I will stand my ground that these are the essentials and nothing extra will make you any faster.
