Several riders will use this fixture not only for a "warm up" for Badminton several weeks later but also to gain the precious Olympic qualifying points, to earn a place at Beijing 2008.
Riders that are nail bite-ingly close to individual Olympic qualification are Michael and Trish Ryan, Jayne Doherty, Niall Griffin, Sasha Pemble, and Geoff Curran.
Every effort has been put in place so that the event runs smoothly and even Margaret Spiers has come in out of retirement to show off her fabulous secretary skills, with Len Caskey at the helm as president and his right hand lady and international eventing judge Jean Mitchell playing the key role of event director.
Ginny Elliot the new Irish performance manager will be registering for the London marathon on April 12, where she will pound the pavements for charity and is disappointed she will be missing the event.
The ground jury for the three star will consist of Patrick Connolly Carew and Vanda Stewart from Ireland and the president of the ground jury will Les Smith be from England.
The dressage will be the FEI 3-star test B and will run from 8am to 10.30am with horses and riders galloping on the tough cross country phase between 11am and 12noon and to create even more excitement the show jumping will be jumped in reverse order from 3pm to 4pm in the main arena in front of the VIP marquee.
The main sponsors include Red Mills who are launching their new dog food range at the event, Irish vet P.J McMahon who is also vet to the USA Eventing Team, Achievers a Dublin based specialist recruitment company run by sporting enthusiast Paul McGrath, Isaac Agnew, and Climate Design owned and run by one of Dublin well known bachelors Rowan McKevitt whose impressive client list includes Anglo Irish Private Banking, Kelloggs, Supervalu, and Centra to name a few.
Ian Stark, former British Eventing medal winner, has been course designer for all three Tyrella Events in 2008.
He watched Tyrella event running last spring and was delighted to hear that he would be adding the design of the three star course to his repertoire.
Ian's son Tim has been following in his father's footsteps helping hard working Tyrella course builder Cyril, and Tim has also built several of the portable fences for the event.
Ian said: "There is lots of scope and ground is excellent and it is great that it can run at this time of the year, and the ground coped well with the wet weather last weekend.
"It is an attacking galloping course, not twisty with a big ditch at the second fence and fourth fence is in to water. Riders and horses will be straight into the course, with no warm up and have to be ready and firing from the word go. There are generous strides, and anyone going in a forward rhythm will find it a good course to ride"
"There are new double of corners near the house and that will be interesting fence which has no alternative. Riders will have to swallow the bravery pills and go for it. The course will consist of mainly new fences and fences that have not been jumped already in Tyrella one and two."
Commenting on the course, Dennis Currie said: "The track at Tyrella is big and bold and mirrors the style Ian Stark the course designer used to ride.
"The event is an exciting prospect with our top Irish riders competing in this event and going on to Badminton, and hopefully the Beijing Olympics 2008 and we hope they will find this course challenging."
Rider Jayne Doherty said: "The Tyrella CIC*** is hugely important fixture in Irish eventing and has been so well supported by riders, Eventing Ireland and the land owner David Corbett.
"If we are to win medals at Championships, we need to build our depth of three star horses in Ireland and Tyrella International three-star will inspire our two-star riders to ascend to three star level, provide qualification for our three star riders for four star level, championships and Olympics and increase competition and therefore results at this level."
