So, it summary - for the OP - If you want to tie your money up in season long accumulators, Boylesports are probably fine. If you want more than 50p each way on a horse that actually has a chance of winning, they are to be avoided because they aren't really bookmakers. By definition, a bookmaker takes bets.
Well,a couple of things,I have more than a passing interest in this subject and have even bought and read a book called 'Speaking in Forked Tounges' by a couple of northerners( well from your part of the world) - see YouTube- who are campaigning on this very subject.
And it's not just Boylesports is it?
My understanding is that they are smaller than most well known bookies? If they were a big bookie then I would be more understanding of the exasperation horse race bettors feel.
As far as 'season long' accumulators is concerned I never got much of a chance to talk about what I do because I kept being criticised .
Had things been different I might have got so far as pointing out that one of the many things I've learned in 17 years of doing what I do is that there is an optimum time for beginning to place long term bets.
And I suspect that almost everyone would be surprised to know just how close to the end of the season that optimum time is.
Plus of course hopefully Boylesports in common with other bookies will eventually allow cash outs on long term bets.
But more importantly,
If you are betting purely to make money you should know that things change and you have to adapt.
If you don't you will fall by the wayside.
I don't care how much someone knows about horse racing,long term sports markets are so fucking easy to beat that anyone who refuses to learn how to do so ( if they don't already know) has no right to complain about bookies not being interested in taking money on a sport that increasingly they have little interest in accommodating,when they are more than willing to take money on those sports that,as I say, are far easier to beat.
Cheers.
