Rapid developments in sport science in the last 20 years have run alongside the technological improvements in racing shoes.<\/p>\n
Simply put, we know more than ever how to ‘beat the wall’ and to keep glycogen levels topped up throughout 26.2miles. <\/p>\n
In Sawe’s case, a research team from sports nutrition brand Maurten spent 32 days with the Kenyan across six trips in the last 12 months.<\/p>\n
Their team, which specialise in hydrogels, worked alongside Sawe to train him to absorb the 90-120 grams of carbohydrates included in the gels within an hour period without feeling distress. <\/p>\n
By keeping glycogen levels topped up, the body can rely on carbohydrates as its preferred form of energy, rather than fat reserves. <\/p>\n
Almost inevitably, when landmark times are set, there are those who raise suspicions. <\/p>\n
Ruth Chepngetich, winner of the 2024 Chicago Marathon in a world-record 2:09:56, was hit with a three-year ban for doping in 2025. <\/p>\n
In light of his countrywoman’s suspension, Sawe and Adidas asked the Athletics Integrity Unit to ramp up his anti-doping testing.<\/p>\n
In 2025, Adidas paid $50,000 (\u00a336,800) to increase the drug testing of Sawe in the build-up to the Berlin marathon. <\/p>\n<\/div>\n
