It’s a sound argument, but it runs up against he fact that there are no Novice or Beginners Chases at this time of the year, only novice handicap chases.
The BHA, in their wisdom, opted to remove all such races from the program between April 1st and September 1st, with the exception of Graded Novice Chases run at Aintree.
Young Getaway could have waited for a novice handicap chase, but they are few and far between, and finding one in your local area, over the desired distance and handicap rating band, would be a matter of luck.
