One of the biggest difficulties I have when betting on jumps is knowing when a horse is running to its full potential and when it is being prepped for a target race or as a handicap plot. One of the most obvious examples of this was Holywell. Before the Cheltenham Festival last year, he had been beaten in two Class 4 chases, won 2 and unseated in another. Despite this, I know people lumped on him to win the Grade 3 Handicap Chase and the Grade 1 Novice Chase following it at Aintree. He is now one of the favourites for the Gold Cup.
So my questions are:
a) How do you spot a horse that is not running to its full potential and so may have more to offer?
b) How do you know when this horse will return to form (or which race it has been prepped for) and win at (probably) massively inflated odds?
I will give my thoughts on the two topics and am more than happy for the more educated of you to correct me as appropriate (although if you want to agree I'm more than happy for you to do so

a) This is the most difficult aspect for me. Particularly over the jumps it seems very easy for horses to improve from nowhere (that said I don't watch most races as 5mins for a jump race is very different from 90secs for a flat). So the (few) markers that I have come up with on NH for reasons for horses to improve next time are:
- Horse held up and never has a chance to get into race (a la Boston Bob in JNWine Champion Chase). However how do you differentiate between held up and never getting into race, and held up and not good enough?
- Horse travels well but fades towards the end of the race (a la Uxizandre in Old Roan Chase) But at what point do we expect the horse to tire? I use around 2f on flat, but is it more over jumps?
- Horse is campaigned over hurdles to protect chase handicap mark (a la nearly any Grand National horse)
b) The only thing I can think of to use for knowing when horses will improve is they are racing in a big handicap - usually at a big festival. But what about the C3/4 horses who are never going to run in the big handicaps? How do we know what their targets are (or do we not)
- In terms of preparation races, I tend to see a horse that has run around 30 days before a big race as a positive for it being a prep race for this one. Does anyone have any thoughts on whether this is a good train of thought or not?
Apologies if that's a bit of a long read guys, but I tend to struggle a lot with NH compared to the flat so any help you can give is massively appreciated.
