May 31, 2025 – London
Amazon Prime Video has officially announced the release of an in-depth, four-part documentary titled “Against the Clock: The Art of the Time Trial,” shining a spotlight on one of the most technical and mentally demanding aspects of competitive cycling — time trial positioning.
Set to premiere in July 2025, this immersive series promises to take viewers on a behind-the-scenes journey into the strategic and scientific world of time trials, a race format where riders compete alone against the clock and where the tiniest aerodynamic changes can separate champions from the rest.
A Focus on Aerodynamics and Precision
Each episode of Against the Clock examines how elite cyclists, coaches, and engineers work together to refine time trial positions — often down to the millimeter — to minimize air resistance and maximize efficiency. With exclusive access to training sessions, testing labs, and real-time race preparation, Amazon’s newest sports series explores the world of marginal gains in cycling like never before.
Executive producer Lena Mitchell, known for her work on several acclaimed sports documentaries, said the goal was to showcase the deep intersection of athletic ability and technological advancement.
“Time trials aren’t just about raw power,” Mitchell explained. “They’re about the pursuit of perfect positioning, where every inch of a rider’s form can affect the final outcome. We wanted to show viewers how every decision, every adjustment, matters.”
Featuring Cycling’s Top Time Trialists
The documentary includes intimate interviews and insights from some of the sport’s premier time trial specialists, past and present. Among the featured athletes are:
- Filippo Ganna (Italy), one of the most dominant time trialists of his era
- Chloe Dygert (USA), an Olympic silver medalist with a background in both track and road cycling
- Primož Roglič (Slovenia), a former ski jumper turned Grand Tour winner
- Geraint Thomas (UK), the 2018 Tour de France champion known for his versatility
- Ellen van Dijk (Netherlands), a multiple-time world champion in the discipline
These athletes walk viewers through their bike fitting sessions, aerodynamic evaluations, and mental conditioning as they prepare for some of the most grueling individual races in cycling.
Detailed Episode Breakdown
The four episodes are each dedicated to different components of the time trial experience:
- Episode 1 – “Position is Power”: This episode delves into how professional riders collaborate with bike fitters and biomechanics experts to fine-tune their position on the bike for optimal speed and comfort.
- Episode 2 – “The Wind Doesn’t Lie”: Viewers are taken inside state-of-the-art wind tunnels and computational fluid dynamics (CFD) facilities to see how teams test gear, clothing, helmets, and riding posture.
- Episode 3 – “The Hour Record”: This episode follows modern attempts to break the prestigious hour record, where cyclists ride the farthest distance possible within 60 minutes on a velodrome. It highlights both the physiological and technical demands of the feat.
- Episode 4 – “Time Trial, Mind Trial”: A psychological look at racing solo against the clock, where riders must push themselves to the limit without drafting, teammates, or external pacing.
Engineering Meets Endurance
Against the Clock doesn’t stop with the riders. The documentary also brings in insight from cycling engineers, aerodynamicists, sports physiologists, and team directors from leading WorldTour outfits like INEOS Grenadiers, Jumbo-Visma, and Team SD Worx. These professionals help paint the full picture of how every element — from the shape of a helmet to the texture of a skinsuit — is scrutinized for time gains.
Former pro cyclist turned analyst David Millar adds commentary throughout the series, emphasizing the razor-thin line between success and failure in time trialing.
“Time trials are like high-speed chess — except every move is made in motion, and the clock never stops,” Millar says. “It’s where science, strength, and strategy collide.”
Global Premiere and Availability
All four episodes of Against the Clock will debut on Amazon Prime Video on July 12, 2025, and will be released simultaneously worldwide. The series will be available in multiple languages through subtitles and dubbing, ensuring fans across the globe can experience the story.
Whether you’re a hardcore cyclist, a fan of endurance sports, or someone fascinated by human performance and innovation, Against the Clock promises to deliver a compelling look into a world where every second truly counts.
