Actual start of a race

[Dices]

Hi everyone , sorry if this is not the right place for the post. I'm trying to find a way to "predict/know" the time that Betfair suspends the race (because it has just started), let's say 10secs or less before the suspension. eg a radio that comments the race and says " they just left " , something like this. With the BF delay I will know that the market will suspend in the next few secs. Are there such sources? radio, tv , sites , services? free or paid? UK and IRE races / International BF user Thanks
