The author details a profound personal transformation from a sedentary lifestyle, marked by struggles with short runs and significant back pain, to becoming a dedicated ultra-marathon runner preparing for the prestigious Comrades Marathon. Seven years ago, at 47, the author could barely complete 5 km and weighed 72 kg, suffering from severe back pain. Advised by a physician to take up running, initial attempts led to injuries and long breaks. His lifestyle was characterized by late nights, frequenting bars, and a lack of discipline.
This narrative traces a journey of significant physical and mental change. Since January 2026, the author and his running group have collectively logged 1,330 km, averaging 66 km per week. This training has progressed from short runs to ultra-marathons, including a 65 km race in the Himalayas, with endurance tested through runs lasting five to eight hours. The Comrades Marathon, an 86 km race with a demanding 1,800 m vertical ascent, represents the culmination of this effort, a stark contrast to the 120 m elevation gain of a standard marathon.
Technological tools, including AI like Claude and Monte Carlo simulations, were employed to model race probabilities and strategize training. Key figures in this transformation include friends Dr. Rajesh Benny and Nagarajan, who provided consistent support, and coach Satish Gujaran, who meticulously increased training volumes. Personal trainer Mangesh Pandey emphasized the importance of core, plyometric, and leg strength training, often overlooked by runners.
The author recounts his progression through various race distances, starting with a 21 km race in late 2023, followed by the Tata Mumbai Marathon (42.2 km) completed in 5.5 hours. He then increased his weekly mileage to 15 km, improving his marathon time to 4 hours 55 minutes. The decision to target the June 2026 Comrades Marathon was made in May 2025. Qualification required a marathon under 5 hours, which was achieved. Despite a discouraging performance in a later marathon, the author's resolve was strengthened by completing the Tata Ultra (6 hours 1 minute) and the Ganpatipule Ultra Marathon (56 km in 7 hours 2 minutes), and the Kalimpong race (65 km in 8 hours 18 minutes).
Reflecting on the motivation behind such extreme endurance challenges, the author cites ultrarunner Stephanie Case's perspective that long-distance running is a form of 'suffering well,' a privilege that offers a unique form of resilience. With 20,000 runners participating globally, including 235 from India, 120 of whom are debutants like himself, the author aims to complete the Comrades Marathon within 10 hours 45 minutes.
