distance betting !!!

Depends on where you placed the bet.

13.4Winning Distance Bets
Unless stated otherwise in the Market Information, winning distances' bets are on the sum of the winning distances from each race on one particular day at a race meeting.
The winning distance in a race will be the officially declared distance between the first two horses past the post. However if either the first or second horse past the post is disqualified because: (i) of an incorrect weight carried; (ii) they have taken the wrong course; (iii) the jockey of either horse fails to weigh in, or weighs in light after the race; then in each case the winning distance shall be that between the first and second horse under the official result.
For the purpose of this bet, the maximum distance on any individual race will be 12 lengths for Flat races and 30 lengths for National Hunt races (which includes National Hunt Flat Races) and these distances will be applied where only one horse finishes a race. For distances below half a length, the following scale will be applied:
Nose: 0.05 length
Short-head: 0.1
Head: 0.2
Short-neck: 0.25
Neck: 0.3
If a meeting has three or more races abandoned or declared void, then all 'winning distance' bets will be void, unless the entire market has been unconditionally determined.
When only one or two races are abandoned or declared void, then 'winning distance' bets will be settled with a default distance used for each abandoned or void race. The default distances are 2 lengths for Flat races and 10 lengths for National Hunt races.
In the case of a walkover the following distances will be applied:
Flat: 5 lengths
National Hunt: 12 lengths
