Bookmakers were floored by "painful" Cheltenham Gold Cup day results as four of the big favourites won.
Punters celebrated a stretch of well-backed winners – including the big race hero A Plus Tard. Sent off the 3-1 market leader, the tough chaser helped earn Rachael Blackmore a place in the history books.
As he raced 15 lengths clear, the 32-year-old became the first female jockey to win the Festival feature. Vauban (13-8f), State Man (11-4f) and Billaway (13-8f) also headed the betting for their respective races – and they were part of an amazing five-timer for Willie Mullins.
