It's understandable if there's a chance races can be rescheduled within a 2/3-day meeting but there's no meeting scheduled for Sunday so in this case stakes should be refunded.
Edit - B365 have refunded my chunky bet on Prince Escalus.
Christ. How long can it take to decide whether to reschedule or not?
I imagine they will be trying to work out if they should save all the graded races . It may be out of the box a bit but I would move the International to Festival trials day . The race has always struggled a bit since the Christmas Hurdle was made a Grade 1 and I bet CH would run in it with the Contenders Hurdle having been abolished and the Haydock race is not a CH trial no matter what they call it .
BHA say the races lost over the weekend will not be rearranged.
