Science Supplements Cup

The Mitsubishi Motors Cup

The Science Supplements Cup is the official name for the grassroots eventing championships that take place each year at Badminton House ahead of the main five-star Badminton Horse Trials.

The competition first moved to Badminton in 2010, as the Mitsubishi Grassroots Championship and in 2016 was renamed the Mitsubishi Motors Cup.

When Mitsubishi called time on their sponsorship of Badminton after the 2019 event, the event was rebranded as the Science Supplements Cup, although the cancellation of Badminton in 2020 and 2021 means the competition is yet to run under that banner.

The first year that the grassroots championships ran at Badminton the cross-country was on the same day as the first day of dressage for the showcase class, which caused some issues with top-level horses being excited by the tannoy and cross-country atmosphere. The timetable was subsequently changed so the grassroots cross-country has since always been scheduled on the trot-up day for the main event.

The competition takes place at BE90 and BE100 levels. The traditional route to qualification has been via fiercely contested regional finals around the country, but British Eventing revealed at its 2020 AGM that these would be replaced by area festivals, which would provide a target in their own right, as well as being part of the route to the championships.

The opportunity to ride on the hallowed turf at Badminton has caused huge excitement among grassroots riders ever since the championships moved to the Gloucestershire event. The event has fuelled interest in these levels of eventing and bolstered the market for horses which can be competitive in BE90 and BE100 classes.
