ITV Racing presenter Ed Chamberlin has said racing commentator John Hunt will be kept "in our thoughts" during the July Festival at Newmarket.
Hunt's wife and daughters were killed with a crossbow on Tuesday in the quiet cul-de-sac of Ashlyn Close in Bushey, Hertfordshire.
A minute silence was held for Hunt during Ladies Day, the first day of the festival taking place at Newmarket Racecourse in Suffolk.
Racing commentator Chamberlin, 50, introduced ITV's coverage of the racing, and said: "We should be excited about the start of the July festival.
"But as I'm sure you've seen in the news, leading commentator John Hunt's wife and two daughters were killed yesterday in their own home.
"We will have four live races for you with John and his family very much in our thoughts."
Fellow racing commentator Richard Hoiles, a friend of Hunt, paid tribute to his colleague at the start of ITV's programming.
Hoiles said the commentator would often talk about his wife, Carol Hunt, and two daughters, Hannah and Louise, and recalled how, at an "annual shindig at Christmas 20 odd years" he proudly showed pictures of his daughters to people in the pub.
"It's impossible to rationalise such a heinous, pointless and terrible act in modern day society really," he said.
"I've known John for 30 years. We started out together and during that time he's become one of the most respected and liked members of the press room.
"Respected because of his fantastic ability, not just in racing, but in other sports such as swimming for the BBC at the Olympics.
"And liked because of his easygoing personality, good sense of humour, his excellent company and, if you spend even a few moments in his company, the odds are that the talk will turn to family.
"There's plenty of people in the press room - I have no idea of their family.
"But we all felt we knew Carol and the girls, possibly far better than we actually did.
"It has been a folklore that after our annual shindig at Christmas 20 odd years ago we'd all retired to the local pub and out would come John's wallet with pictures of the girls at primary school, who he'd share with random bar staff and anyone else who would care to listen."
He added: "In the helter skelter of modern-day life it's quite easy to lose track of the things that we hold dear, but John never has.
"I know I hugged my kids tighter last night on leaving for here. Knowing that that simple pleasure has been cruelly snatched away from one of mine, and many in the press room's, greatest friends.
"Words just seem hollow and inadequate in such circumstances and all we can try and do is provide some crumb of comfort by trying to exhibit the warmth and respect in which John and his family is held, as will be shown by the many tributes that will be held up and down the country today."
