Dave Nevison's tips: three best bets for Thursday

Unlike many in this field, Unspeakable still seems to be progressing, albeit at a modest rate from a low base.

He has been contesting low-grade handicap hurdles and chases this season but has definitely run better over fences, and produced a career best last time out. 

The application of a tongue tie might well have aided his performances on his past two starts, and he does not have to improve again to go very close in this weak contest.

This extreme test of stamina looks like being just the ticket for Stellar Stream who finished well to snatch second behind the very progressive Katate Dori (one of the favourites for the Ultima last week) on his latest start, and he certainly isn't up against anything of that calibre on Thursday. 

He ran well in cheekpieces last time out and hopefully the application of first-time blinkers, plus stepping back up an extra half mile, can bring about further improvement. 

Callum Pritchard claims his full 5lb allowance here, and that will be a great help at the end of this marathon trip.

Keppel Queen quickly returned to hurdling after she fell over fences on her penultimate start, and the switch back saw her return to decent form under this rider, Benjamin Macey, who has finished runner-up on the two occasions he has rode this mare.

The selection has run a decent race already over this course and distance, so is clearly suited by the track, and with her jockey able to claim this time, she might be able to finally break her maiden.
