How Jacob Kiplimo uses data from his Galaxy Watch to achieve world-record performances

Jacob Kiplimo, the acclaimed Ugandan long-distance runner and TeamGalaxy athlete, has been leveraging the power of data to enhance his performance on the track. With the assistance of his Galaxy Watch8, Kiplimo transforms biometric data into strategic insights that contribute significantly to his training and racing success.

This synergy between technology and innate talent has already delivered impressive results. Following his commanding victory at the 2025 Chicago Marathon and setting a new half-marathon world record in Lisbon earlier this year, the 25-year-old now aims to excel at the 2026 London Marathon.

In celebration of World Health Day 2026, Samsung Newsroom invited Kiplimo to share insights into his data-driven training regimen that aligns with this year’s theme, “Together for health. Stand with science.” Through exclusive access to his Samsung Health metrics, Kiplimo provides a glimpse into his rigorous training schedule, which includes running over 100 km in a single week. His data-driven approach allows him to optimize recovery, even incorporating a “rest day” with a 3 km run.

Kiplimo acknowledges the critical role of discipline in his success, emphasizing the importance of hard work, focus, and energy management. He credits his Galaxy Watch8 with enabling his coach, who resides outside Uganda, to monitor his performance remotely. The watch’s Running Analysis feature provides real-time data on his running form, heart rate, and pace, helping him make informed adjustments to prevent strain and improve running efficiency.

Consistency is a cornerstone of Kiplimo’s training philosophy, balanced by the understanding that rest is as vital as physical exertion. He explains that technology aids in maintaining this balance, allowing him to listen to his body and adjust accordingly. For instance, data from his Samsung Health app guided him to reduce a planned 40 km run to a 3 km jog when he experienced soreness, preventing potential injury.

For those new to running, Kiplimo advises patience and gradual progression. The Running Coach feature of the Galaxy Watch8 offers personalized training programs, providing guidance and motivation for both novices and seasoned runners aiming for marathon success.

On World Health Day, Kiplimo reflects on the role of science in his training, expressing gratitude for the data-tracking capabilities of his Galaxy Watch8. He believes that science and technology are instrumental in achieving peak performance and can empower others on their journey towards healthier living.
