Countifs Until Criteria Is Match

I am looking for some help, I have been searching the forums all morning but have failed to come up with a solution so I am looking to the members expertise for help!

Here is a basic setup of my table.

Column A - Dates
Column B - Type (Flat, AW or NH)
Column C - Runner (Horse Names)
Column D - Result (Won, Place or Lost)

Now this is what I am trying to achieve, I want to count the number of rows UNTIL the results column produces "Won" but I have multiple if functions.

The Countifs formula would be =Countifs([Column A],"<"&[@[Column A]],[Column B],[@[Column B]],[@[Column C],[Column C])

This obviously counts the whole workbook, I want it to count only up to the first instance of 'Won' in Column D and the have it reset for the next row and count until the next 'Won' again and so on until the end of the workbook.

For example

20/02/2013 AW Abigails Angel Lost - Count would be 2
11/01/2013 AW Abigails Angel Placed - Count would be 1
27/12/2012 AW Abigails Angel Won - Count would be 5
24/10/2012 AW Abigails Angel Placed - Count would be 4
25/08/2012 AW Abigails Angel Lost - Count would be 3
12/08/2012 AW Abigails Angel Lost - Count would be 2
19/07/2012 AW Abigails Angel Placed - Count would be 1
11/06/2012 AW Abigails Angel Won

Hope I have explained it ok and if not let me know otherwise thank you in advance for any advice/help.

Thank you for the effort but not quite what I am looking for, I guess I should have given a better example of the table. Columns B and C are not all of the same so it would be more like this.....

20/02/2013 AW Abigails Angel Lost - Count would be 2
11/01/2013 AW Abigails Angel Placed - Count would be 1
27/12/2012 AW Abigails Angel Won - Count would be 3
24/10/2012 AW Abigails Angel Placed - Count would be 2
25/08/2012 FLAT Abigails Angel Lost - Count would be 2
12/08/2012 FLAT Abigails Angel Lost - Count would be 1
19/07/2012 AW Abigails Angel Placed - Count would be 1
11/06/2012 AW Abigails Angel Won - Count would be Blank as no Previous Win
10/06/2012 FLAT Abigails Angel Won - Count would be Blank as no Previous Win
20/02/2013 AW Bobs Delight Lost - Count would be 5
11/01/2013 AW Bobs Delight Placed - Count would be 4
27/12/2012 FLAT Bobs Delight Lost - Count would be 1
24/10/2012 AW Bobs Delight Placed - Count would be 3
25/08/2012 AW Bobs Delight Lost - Count would be 2
12/08/2012 FLAT Bobs Delight Won - Count would be Blank as no Previous Win
19/07/2012 AW Bobs Delight Placed - Count would be 1
11/06/2012 AW Bobs Delight Won - Count would be Blank as no Previous Win

So what I need is what you have given me but with multiple conditions inserted into it. Is this possible?
