No horse racing took place in the UK on Wednesday as part of a historic protest against the government's proposed betting tax rise.
The British Horseracing Authority's strike meant it was the first time in modern history it had voluntarily refused to race.
Meetings at Lingfield Park, Carlisle, Uttoxeter and Kempton Park did not take place and were rescheduled.

Why was there no horse racing in the UK on September 10
The BHA strike came in response to a UK government proposal to align tax on horse race betting with the 21% levy on online games of chance. Horse race betting is currently taxed at 15%.
The UK government is set to announce its Autumn Budget in October.
Senior racing figures, including owners, trainers and jockeys also attended a campaign in Westminster to highlight what they perceive to be the threat of the Treasury's proposal.
Analysis commissioned by the BHA suggests the tax increase would cause a £300million revenue hit for an industry worth £4.1billion to the IK economy, putting 2,752 jobs at risk.
Jockey Tom Marquand told Sky News: "If you take away money, all it will do is dilute the funds that are propping up [racing]. Owners need to be winning money for races to be able to pay for horses' upkeep and training costs.
"It's almost like taking a Jenga block out of the pile and not expecting it to fall down. Inevitably, if you take out the base, the rest crumbles.
"And racing is very much an example of that. If the funding goes, everything else crumbles around it because it's such an important part of the sport."
