This afternoon's thetote.com-sponsored Gold Cup and the other scheduled chase on the card at Punchestown have both been cancelled due to weather conditions.
The County Kildare track has been hit by a deluge of rain ahead of day two of the Festival together with strong winds.
A five-race card, comprising of three hurdle races and two bumpers, will now get under way at 4.55pm.
Punchestown's PR Manager Shona Dreaper said: "We are racing today with a five-race card, beginning at 4.55pm.
"A designated route has been planned through the enclosures to get 1,200 hospitality guests to their destinations.
"The shopping village will be closed initially, but could be opened later, and all other members of the public are going into the grandstand."
It is thought the Punchestown Gold Cup will be rescheduled to take place on Saturday's card, although that has yet to be finalised.
