The advent of betting in running means that punters are no longer disappointed if they fail to place their bet before an event has started.
Traditional bookmakers such as Stan James or bet365 don't offer betting in running on horseracing, but it's very popular where football, golf and cricket, to name but a few sports, are concerned.
In running betting on horseracing is commonplace, however, on betting exchanges such as Betfair.
Football is without a doubt they most popular in-running betting medium with traditional bookmakers, and most offer a huge choice of markets, in many cases the options are almost as plentiful as pre kick-off.
In essence, the odds fluctuate in accordance with the way that the game is progressing. If, for example, Arsenal are playing Liverpool and they are 5/1 to win 1-0 in the correct score market prior to kick-off, if they go 1-0 up say halfway through the first half, their odds might tumble to, for aguments sake, 10/11 to win 1-0 in the correct score market. If, however, it's still 1-0 at the mid point through the second half, the odds about this outcome would have contracted significantly, probably to somewhere in the region of 4/9. Generally speaking, betting in running markets are offered on televised events.
