Athletes competing for Great Britain and Northern Ireland have the option to wear three different coloured kits at the 2026 European Athletics Championships. During last year's World Athletics Championships in Tokyo, GB athletes similarly had the option to wear all three kits. In Tokyo during the men's 1500m semi-finals when Josh Kerr sported a blue and white striped jersey, team-mate Jake Wightman wore a white sleeveless top. A British Athletics spokesperson said athletes were given the choice to help their "individual needs, performance, preferences and comfort". The blue kit is designed with aerodynamic sprint features in mind, while the white sleeveless top and shorts provide a lighter, traditional option for non-sprint athletes.
