Once again rain interrupted the eventing calendar with an unexpected deluge on Friday night resulting in Great Witchingham International Horse Trials organiser David Sayer abandoning the national classes on Saturday as the ground became saturated.

However, by Saturday afternoon it was drying out well and the three-day section was underway.

'We had made the decision to come off the summer meadows course about a month ago,' said David.

'Then we put down almost 80 tonnes of limestone.

'The spring course has all prepared take-offs and landings anyway and we have a great advantage as we have mostly fixed fences, so you're not jumping on fresh ground. This means we can normally guarantee to cope with the wet weather – but that was just too much.'

The cancellation on Saturday meant that the Novice and Intermediate classes were not run, although a full day of eventing was able to take place on Sunday.

The BE100 three-day event concluded in the show jumping arena and it was Norfolk's Georgie Bell and Norton Renee who finished a clear round to take first place. An instructor at the Playbarn Riding School in Poringland, Georgie and her 15-year-old gelding Renee pulled a rare clear round out of the bag.

'His dressage is usually very consistent and he's always a cross country machine, but if you look at his showjumping record he's got about five clears in his whole career – so what a day to pull one out,' said Georgie, who was also celebrating her wedding the week before.

The top class of the weekend was the CIC* and a full field competed.

It was Lincolnshire's Alex Postolowsky, riding Tim, and Antonia Brown's and Sara Lucas' Wow II that triumphed.

Towards the end of Sunday the BE90 classes took place, again with excellent entries – and the ground was still perfect.

Tilly Morgan and Rialton Shadow triumphed in section R, having ridden an unbeatable dressage of 28.5.

The veterinary practice manager from Wymondham said: 'He is always up there with the dressage really and I have an excellent trainer in Tessa Fielder.'

Tilly moved to Norfolk from Surrey a year and a half ago and competes in dressage and show jumping in the local area. She keeps her horse at Whiterails Livery in Great Melton and is now looking to move up to BE100 at Little Downham and Burnham Market Horse Trials.
