2025 Guards Trophy Championship Overview
The Guards Trophy Championship, a cornerstone of the Historic Sports Car Club (HSCC) calendar, showcases an evocative mix of 1960s Sports Racing (SR) and Grand Touring (GT) cars. These classics are grouped into performance-based classes, running exclusively on Dunlop control tyres. New for 2025, the format introduces both split-grid and combined-grid races to accommodate the growing variety of cars.
Each race awards class-specific trophies, and by season’s end, separate champions will be crowned for SR and GT categories, ensuring equal recognition across both disciplines.
Race Format Races are 50-minute mini-enduros featuring mandatory pit stops and optional driver changes. Dual-driver entries are actively encouraged, though solo competitors face no disadvantage. With anticipated grids of 30 or more cars, the Guards Trophy continues to be a highlight of the HSCC season.
New for 2025
- Additional classes for small-capacity sports racers (up to 1,150cc) and large-engine pre-’67 “big bangers.”
- Revised GT class structure to better balance competition:
- New category for up to 1,300cc
- Refined splits at 2,000cc and 3,000cc to distinguish between marques like MGBs, TR4s, and Austin Healeys.
- Invitation classes for both SR and GT categories allow a broader range of historic cars to participate in non-points scoring entries.
