Lengthen Your Odds on all UK races

Lengthen Your Odds is a special betting market that William Hill offers on horse races in the UK.

Place a single win bet on any race in this market and you will be able to boost your odds by predicting the winning margin of your selection.

How William Hill Lengthen Your Odds works

William Hill’s Lengthen Your Odds is not a betting special, but rather a special horse racing market that applies to UK racing.

When you select the market you will get a list of horses competing in the race, along with options to back your select winning the race. Odds are offered on each horse winning the race by:

  • 1 length
  • 2 lengths
  • 3 lengths
  • 4 lengths
  • 5 lengths

The bigger the margin of victory you predict, the higher the odds on offer. Picking your horse to win by 5 lengths will offer a payout several times higher than backing your horse in the straight win market.

When betting on the William Hill Lengthen Your Odds market bear in mind that this bet is effectively a ‘hidden’ accumulator bet, combining two separate bets – winner and winning margin – into one bet.
