A swim cap serves multiple purposes, including keeping hair out of your face, improving hydrodynamics, and enhancing visibility in open water. Choose a high-quality silicone swim cap that stays securely in place during your swim. Most competitions supply you with their own swim cap.

Cycling Gear


Triathlon bikes, also known as time trial (TT) bikes, are specifically designed for the cycling portion of a triathlon. These bikes offer several features that enhance speed and performance. One key characteristic of a triathlon bike is its aerodynamic design. The frame geometry, including the elongated top tube and steep seat tube angle, promotes a more forward-leaning riding position that reduces wind resistance and improves overall aerodynamics. This allows triathletes to maintain higher speeds with less effort, especially during long straights.

There are different types of triathlon bikes available, each with handling characteristics to suit various courses and riding preferences. One popular type is the traditional triathlon bike, which emphasizes aerodynamics and stability. These bikes often have deep-section carbon wheels, horizontal handlebars, and specialized aero bars, allowing riders to adopt a more aggressive, aerodynamic position.

Another option is the triathlon-specific road bike, which combines the speed of a TT bike with the versatility of a road bike. These bikes typically feature a more relaxed riding position and are well-suited for courses with varied terrain, such as hills or technical sections. They offer greater comfort and handling capabilities while still maintaining decent aerodynamics.

The handling characteristics of triathlon bikes focus on stability and straight-line speed. They are optimized for efficient pedalling and smooth handling during long rides. The longer wheelbase and lower bottom bracket height contribute to added stability, making triathlon bikes reliable in maintaining control at high speeds.

Triathlon bikes are designed with aerodynamics in mind, allowing for increased speed and efficiency during the cycling portion of a triathlon. Different types of bikes cater to specific preferences and course requirements, providing options for both aggressive aerodynamic positions and versatile handling. Whether you opt for a traditional triathlon bike or a triathlon-specific road bike, choosing the right bike can greatly enhance your performance on race day.


Safety helmets are a crucial piece of equipment for triathletes, providing protection and reducing the risk of head injuries. Different types of helmets include road helmets, which prioritize ventilation and aerodynamics, and time trial helmets, which offer improved aerodynamics and a more streamlined design specifically for triathlon cycling stages.

Cycling Shoes:

Cycling shoes are a vital component, serving the purpose of maximizing power transfer and efficiency during the cycling portion of a race. These specialized shoes are designed with stiff soles to enhance pedalling power and ensure every ounce of energy is transferred to the pedals. They often feature a clipless pedal system that allows athletes to securely attach their feet to the pedals, increasing control and reducing the risk of slippage. Additionally, cycling shoes have ventilation and adjustable closures for comfort and tailored fit during long rides.

Bike Shorts and Jersey or Tri suit:

Cycling-specific apparel made of moisture-wicking fabric is crucial for comfort and improved performance. Invest in padded bike shorts to minimize chafing and provide extra cushioning during long rides. Pair them with a breathable jersey that offers pockets for storing nutrition and essentials. But most triathletes opt to wear a tri suit – WHAT EXACTLY IS A TRI SUIT? A triathlon suit is the only clothing you will wear from the start of a triathlon until the finish line. As it isĀ designed for swimming, biking, and running, the pad is thinner than on biking shorts, but it dries faster, and it is not disturbing you while swimming and running.

Running Gear

Running Shoes:
