Britain's Laura Renwick topped off what was an incredible week at Millstreet International Horse Show CSI*** by winning the Noel C. Duggan Engineering €50,000 1.60m Grand Prix.

Riding Heliodor Hybris, the Essex-based rider was one of only three double clears. Owned by Colin Bates, Heliodor Hybris is an nine-year-old gelding by Diamant de Semilly out of the Cannonball-sired mare Carpe Diem Luka.

Renwick said: "I brought Heliodor Hybris to Millstreet specifically for the Grand Prix. He jumped once on the Friday then in the Grand Prix. I'm really pleased with how he performed and also with my eight-year-old Irish-bred mare MHS Washington who won Saturday's ranking class and then was fifth in the Grand Prix. I always love to come to Millstreet and it's a great opportunity to bring young horses to contest the prestigious finals, an excellent result to top off a good week."

Swiss course designer Gerard Lachat set the challenge for the 32 starters and with riders facing a technical track, just seven maintained clean sheets first time out. Along with these seven combinations, the fastest four-faulter also proceeded to the second round.

Out of luck

First to go carrying four faults, Dermott Lennon and Valent proved out of luck when they added a further eight faults to their tally and finished on 12 faults for eighth place.

Double handed in the jump-off, Laura Renwick proved out of luck when she faulted at the second vertical with MHS Washington (ISH), but a fast time of 53.72 saw her take fifth place.

County Meath's Alexander Butler and Monastery Stud More Pleasure faulted at the fourth vertical and finishing on a total of four faults in 58 seconds saw him take seventh.

Next in Jessica Burke and Dermish Cruise kept all the poles in place but two time faults when clocking 68.70 meant she had to contend with fourth.

The first double clear came courtesy of Edward Butler who partnered Cornet Son to a faultless performance in 60.85 to take the lead. Despite a blistering round from Butler, his lead was short-lived as Liam O’Meara lowered the target to clear in 58.63 with Mr Coolcaum. Next to take it on, Holly Smith set off in a blistering pace with Lammy Beach, but she was ruled out of contention early when faulting at the third oxer and her final score of four faults in 55.91 meant she finished in sixth place.

Last to go, all eyes were on Laura Renwick as she took it on with Heliodor Hybris. Renwick made up the time towards the end of the course and crossed the line in 56.34 to take the win and, in the process, demoted O’Meara to second and Butler to third.
