Fitter Radio Triathlon Podcast

Ingmar Jungnickel, an expert aerodynamicist, earned this distinction for his work with US Speedskating, where he developed a revolutionary team pursuit technique known as the 'American Push'. This strategy used advanced simulation and computer modeling to help the team break world records.
His career includes:
Specialized Bicycles: He led the aerodynamics department, overseeing the development of high-performance bikes like the S-Works Tarmac and Venge.

US Speedskating: He serves as the Chair of the Sports Science Commission and is the 2018 US Olympic Committee Sports Science Coach of the Year.

Innovation: He is the founder of AiRO, an AI-powered platform that uses computational fluid dynamics (CFD) to provide aerodynamic bike fitting without a wind tunnel.

Aerodynamics plays a significant role in cycling performance, often more so than the weight of the bike. Ingmar emphasizes that many athletes mistakenly believe that a lighter bike is the key to speed. However, the real challenge lies in minimizing aerodynamic drag. 
By focusing on reducing drag, cyclists can improve their efficiency and speed without the need to invest heavily in new equipment. This insight is crucial for all cyclists, particularly those who may not have access to high-end gear or professional training.
One of the most exciting developments at AiRO is the introduction of the Digital Airo Twin technology. Ingmar explains that this innovative approach allows for the creation of a 3D model of an athlete based on just a few photos. This model can then be adjusted for various parameters like limb length and body fat percentage, enabling customized aerodynamic assessments.
This technology democratizes access to aerodynamic testing, making it feasible for everyday athletes to optimize their performance without the high costs associated with traditional wind tunnel testing.

Julie Derron's Olympic silver was a milestone, but for her that was just the beginning. She's simultaneously exploring her potential at IRONMAN - aiming for a breakthrough on the Big Island - whilst keeping her foot firmly on the pedal in middle-distance racing. In this episode, Julie Derron shares insights on training, racing strategies and her plans for Kona qualification.
Julie opens up about the challenges of transitioning between short course, middle distance and IRONMAN racing and the mental resilience required to excel at the highest levels.
