Dear MAYTHEHORSEBEWITHU just automatically backing every horse a jockey rides is well known to lose money over the long term. Similarly each way betting on the tote is generally very poor value, as is automatically each way betting every horse. The maths of each way betting shows you are best backing short priced horses each way with bookmakers (definitely not the tote) in fields of 8 runners. But punters, as a group, being losers do the exact opposite. Back horses at long odds each way in big fields. That's also why all bookies are happy to bet each way in those races but many do not bet each way in fields of 8 to 10 runners.
