Kieren Fallon added a floral tribute for the two apprentice jockeys who died in an apparent arson attack as investigators continued to try to establish how the blaze began.
Flowers from the six-times champion jockey were placed on the gates which lead to the flats where Jamie Kyne, 18, and Jan Wilson, 19, perished early on Saturday morning.
They died when a fire ripped through a three-storey block of flats in Norton, near Malton, North Yorkshire.
Fallon's bouquet said: "You will be missed everyday. RIP. With love Kirsty and Kieren Fallon."
Another message described Kyne as a "gent of racing" and one said they would miss his "cheeky smile and witty banter". These tributes were placed alongside more than a dozen others just yards from where the blaze broke out.
Fire investigation officers moved into the flats complex to begin a painstaking examination of the scene.
It is understood the staircase was destroyed in the fire - an outcome which delayed both the rescue operation and the recovery of the two bodies.
The work to establish the exact cause of the fire could take up to three days to complete, police said.
A local man in his 30s, who was arrested on suspicion of arson with intent to endanger life shortly after the fire broke out, has been released by police on conditional bail pending further inquiries.
There were thought to be six people in the flats in Buckrose Court when the fire broke out. Earlier, they had been celebrating after receiving their "pool money" from a local trainer, witnesses said.
