Why Brick Sessions May Not Be the Best Fit for Triathletes

How Aerodynamics Matters for Every Triathlete, Not Just Pros

Update Aero Matters: A Game Changer for PerformanceWhen it comes to triathlons, one of the nagging questions that many athletes ask is, "Does aerodynamics really matter if I'm not a professional?" After all, most triathletes are amateurs just hoping to complete their races in good time. This inquiry led me to explore the effectiveness of various aerodynamic upgrades from a practical standpoint.In 'Does Aero Matter If You Aren't a Pro?', key insights about aerodynamics were explored, offering a profound look into how performance can be optimized even at amateur levels. Understanding Aerodynamics in layman's termsAerodynamics, in simple terms, is how air interacts with an object — in this case, a cyclist on a triathlon bike. In my journey through a wind tunnel, we tested various setups at speeds that are typical for age group racers, around 30 to 40 kilometers per hour. Surprisingly, the data revealed that a significant portion of resistance cyclists face comes from aerodynamic drag rather than simply rolling resistance or friction.Comparing Bike Positions for Maximum EfficiencyWe began testing with different bike positions—a relaxed upright position, the drops, a tucked hood position, and of course, aero bars. While it may seem trivial, the difference between these positions can result in watt savings that impact your finish time dramatically. For instance, switching from an upright position on the hoods to drops provided nearly an 8-watt boost at 30 km/h and an impressive 19 watts at 40 km/h. This translates to critical time savings during an Ironman!Budget-Friendly Modifications for Weekend WarriorsYou might not be able to invest in a state-of-the-art triathlon bike, but there are ways to optimize your setup without breaking the bank. Adding clip-on aero bars to a standard road bike could contribute to similar gains in power and speed. The experiments revealed around 30 watts of savings at 30 km/h simply by adopting a more aerodynamic stance and using clip-on aero bars, which are commonly available and relatively affordable.Understanding the Importance of Fit and PositionIt’s crucial to recognize that simply acquiring the right equipment isn’t enough. As demonstrated during testing, optimizing your position on the bike significantly affects your performance. Even minor adjustments, such as widening your armrests, allowed for energy savings that might surprise you. Exemplarily, the difference between a well-fitted road bike and a time trial (TT) bike diminishes as one hones their positioning.Long-term Effectiveness: Train for SustainabilityAs I learned, maintaining an aerodynamic position throughout your race is essential. Fatigue can quickly lead to a rise in head position, potentially costing you critical minutes as you fight against drag. Training to reinforce your endurance in these positions not only enhances performance but does so without the need for constant expenditure on new gear.Practical Steps to Improve Your Triathlon GameThe data clearly showed that aerodynamics matter for the aspiring age group triathlete. Innovations like aero helmets can deliver further watt savings, with improvements seen even greater under race conditions. This insight signifies that every second counts when you’re racing, and focusing on your position and how you interact with the wind should be a priority before diving into expensive upgrades.IDoes aerodynamics really matter for you? Absolutely! Understanding this core principle can have a momentous impact on your overall triathlon performance. So why not embrace these findings? Check your bike fit, train for the desired positions, and consider minor adjustments to gear—your finishing time may thank you!
