They’re fast, but are they fair? Amateur runners face Nike dilemma

British amateur runner and triathlete Holly Grundon was delighted to smash a long-held personal speed target to race a half marathon in less than 1 hour and 30 minutes. But the 36-year old’ s decision to switch to Nike’s much-talked-about Vaporfly trainers before securing her new “personal best” time now has her wondering if she somehow cheated herself, or dirtied a sport she’s always loved for its purity. Scientific studies as well as anecdotal evidence suggest that Nike’s Vaporfly running shoes, equipped with super-springy foam soles encasing a carbon-fibre plate, can increase running efficiency by between 4% and 6% – a prospect that has persuaded millions of would-be personal record breaking amateur athletes to ditch their old favourites and give Nike a go.
