DR ALLEN LIM

WHO IS DR ALLEN LIM?

Dr Allen Lim is the sports physiologist who turned the World Tour kitchen on its head. As director of sports science at Garmin–Slipstream and personal physiologist to riders including Lance Armstrong, Levi Leipheimer, Christian Vande Velde, and the Schleck brothers, he was inside the rooms where modern endurance fuelling shifted from sports-drink-and-bar standards to real food. He founded Skratch Labs, wrote the Feed Zone Cookbook series with Biju Thomas, and has shaped how an entire generation of amateurs thinks about hydration, on-bike fuelling, and recovery meals. His work matters because it sits at the intersection of physiology research and what actually works in a team kitchen on a Grand Tour.

KEY IDEAS

The major positions Lim is known for in cycling and endurance sport.

• →Hydration is about sodium and absorption rate, not just water — the standard sports-drink formulations were too sweet and too low in electrolytes.
• →Real food on the bike (rice cakes, potatoes, baked goods) outperforms gels for many riders — gut tolerance is the limit.
• →Recovery starts in the first 30 minutes after a hard session and is dominated by carbohydrate, fluid, and protein in that order.
• →Personalised nutrition is not a marketing term — sweat sodium loss, gut tolerance, and energy needs vary by orders of magnitude between athletes.
• →Race-day fuelling has to be rehearsed in training — the day of an event is the worst time to discover a product does not work for you.
