The conventional wisdom says runners need carbohydrates. Many experienced keto runners would disagree — and their performances back them up.
Mark had been running half marathons for years, maintaining a consistent but frustrating 2:15 finish time and carrying an unwanted 20kg. His diet was “healthy” by conventional standards — whole grain cereal, sports drinks, energy gels — but he never leaned out.
The first 6 weeks were genuinely hard. Running performance dropped as glycogen-dependent energy systems adapted. But Mark persisted, knowing that fat adaptation takes time.
With 12kg lost by month 4, running felt effortless in a completely new way. No more mid-run energy crashes. No need for gels. Just steady, sustainable fat-burning energy.
Half marathon PB: 1:58. Weight lost: 20kg. The transformation in both performance and body composition exceeded all expectations.
Pre-run nutrition from our keto breakfast collection and recovery meals from our keto main dishes supported Mark’s transformation.
