In-Play Horse Racing Trading A big edge?

[napshnap]

It really depends on the race length and whether it's flat, short distances (5f -7f) or hurdles over a longer distance (1m to 3m). For me laying in running can only work 100% of the time by laying definite losers and then you're talking odds of +25 and therefore requiring a very large betting bank.

Nothing will ever work 100% of the time and there's no such thing as a definite loser. People who try to make money that way are the ones who lay all the 1000 IR winners, because at one stage it looked a definite loser!

would be interesting to know how many runners that are leading fall at the last in races over 3m, what’s the percentage etc & if there’s a particular class of race that this occurs?

Well if they're miles ahead they usually trade at 1.02 1.03ish....so i'd guess the people who've studied it think about 2%
