The 2026 LeMieux-sponsored Badminton grassroots championships featured a BE100 course designed by James Willis. Riders faced a 2,997-metre track with an optimum time of six minutes and 19 seconds across 21 fences.
The course opened for competition on 5 and 6 May at the annual Badminton Horse Trials. It included obstacles such as the BE Tree Trunk, Tuckwell’s Triple Bar, LeMieux Lake, and the final LeMieux Horseshoe. Organisers provided fence-by-fence photographs to help competitors prepare.
