For Afiq Aznan, the ultra-marathon is not a race against a clock, but a study in structural integrity. He approaches the sport with the technical precision of an engineer, viewing the human body as a machine that requires specific mechanical reinforcements and fuel systems to survive the transition into triple-digit mileage. To him, the distance is a logic puzzle where the variables are muscle fatigue, caloric density, and mental fortification.

This analytical approach was put to its most rigorous test recently at the Road to Muo 5.0, held from December 26–28, 2025. Following a successful 104km finish at the UiTM Ultra earlier in the year, Afiq elected to push his boundaries further, tackling the 125km category along the notoriously flat and exposed Lebuh AMJ highway. The event served as a definitive bridge between his past achievements and his future ambitions, a 21-kilometre extension into a psychological “dark zone” he had yet to fully inhabit.

Afiq’s training philosophy is rooted in a unique cross-disciplinary logic. While most road runners avoid verticality, he embraces tower running as a fundamental necessity for horizontal survival. “To compete in ultra marathon races, strong leg muscles are essential for every ultra runner. By participating in events such as tower running, I am able to increase the capacity of my leg muscles to work for longer periods, endure longer, and reduce the risk of muscle cramps,” he observes. This “hybrid” foundation allowed him to maintain a steady cadence on the highway, where the absence of hills often leads to muscle monotony and premature failure.

Despite the social nature of the local running scene, Afiq maintains a disciplined solitude in his preparation. He belongs to prominent crews like KakiOutdoor Malaysia and We.Runfar, yet he intentionally conducts his Long Slow Distance (LSD) sessions alone. This is a deliberate tactical choice. “When you train alone and do Long Slow Distance runs, you are unknowingly training your mental strength. During ultra races, most of the time you will be alone until the finish line. Therefore, running solo trains mental resilience while also improving endurance to withstand long hours of running,” Afiq explains.

The 125km journey to Muar was also a laboratory for nutritional recalibration. After nearly failing to meet the cut-off time at his previous 100km race due to an over-reliance on liquids, Afiq pivoted to a strategy centred on solid fuel. He rejects the modern industry’s obsession with supplements for the long haul. “I prioritise real food over gels. Gel usage is less effective for me in ultra-distance races. For ultra distances, real food intake is the key to long-lasting endurance,” he states. This shift proved vital when the “Zombie Hour” hit on the highway, a period he managed with tactical power naps to provide a “temporary freshness” to the mind.

Surpassing the 100km mark introduced a new level of sensory degradation, specifically eye fatigue and mental heaviness. Yet, as he crossed the Sultan Ismail Bridge in Muar, the result was a quiet, internal emotional release rather than an outward celebration. “When I arrived at Sultan Ismail Bridge in Muar, there were no words that could describe how I felt. I was overwhelmed with emotion and gratitude because only I truly know the pain and struggles I endured throughout the journey,” he reflects.

Ultimately, Afiq views the 125km distance as an experimental phase for his primary objective: a return to the 168km Route 68 Ultra in 2026. His first attempt at that distance resulted in a DNF, a rare systemic failure he is currently solving through increased mileage and refined discipline. “I consider this 125km race as part of my long-distance training in preparation for the actual Route 68 Ultra 2026 race,” he notes, treating the achievement as data for his next evolution.

Afiq Aznan does not run to find himself; he runs to test the limits of what he has built. His journey suggests that success in the ultra-distance is less about the heart and more about the architecture of the will. As he looks toward 2026, his message remains one of calculated defiance: “Do not be afraid and do not hesitate to unleash your true potential because nothing is impossible. With strong determination and fighting spirit, no one can stop you from succeeding except God Almighty.”
