Equine supplement company NAF (Natural Animal Feeds) will be an associate sponsor of British Eventing’s (BE) amateur championships — the Mitsubishi Motors Grassroots Festival (29-30 May).

This year, for the first time, the championships will be held at the Mitsubishi Motors Badminton Horse Trials (30 April-3 May).

To enable more riders to qualify for this year’s festival no championship was held in 2009.

Tracey Lloyd of NAF said: “We are thrilled to have set up this agreement and to be associated with Mitsubishi Motors and Badminton Horse Trials in such an exciting and eagerly anticipated initiative as the Grassroots Festival.

“We are always keen to support enthusiastic amateur riders in their chosen sport.”
