Horse Racing Nuggets

My mate Dave Renham is a mine of information on uk horse racing.

I am firm believer that if you take the time to carefully assess the past you are likely to make better decissions about the future.

This applies very well to betting on horses as well as to other walks of life.

Dave recently started producing a little column called “Do You Know” for full members over at

This is just a tiny extra on top of all the usual great research learning over there.

Below is a copy of a recent one.


Did you know?

This is a new section that I started last week where I will share some facts and figs that hopefully you will find interesting and useful. Last week I mentioned that Dandy Nicholls had a great record in the Ayr Gold – the result of the 2010 race on Saturday saw Nicholls have the first and second at 14/1 and 8/1. Here are the facts and figs for this week:

  • Did you know that favourites in Novice chases win around 46% of the time? Despite the high strike rate however, they make a loss of around 4% to SP.
  • Did you know that Tony Mc Coy has ridden 23 winners from 104 for Paul Nicholls in the past 5 years? BUT despite a decent strike rate you would have lost £388.90 if you had backed all 104 runners at £10 per bet.
  • Do you know the chances of six National Hunt favourites winning all six races on a six race card? Well statistically it should occur once in every 774 meetings (this is assuming NH favourites win 33% of all races – which they tend to do).
  • Horses that won on the flat last time out lose around 17 pence in the £ if you back them to repeat their win. However, horses that won in National Hunt racing last time out lose under 14 pence in the £ if you back them to repeat their win.
  • Since 2005 Frankie Dettori has won just over 20% of the races he has ridden in. However, despite that he has had a losing run of 31.

ROI In Horse Racing

ROI In Horse Racing

I received a question from someone new to betting on horses.

They had seen me refer to ROI and wondered what that meant.

Quite simply ROI stands for Return on Investment.

It is a way to measure the profitability of a set of betting selections
whether they be your personal picks, system selections or a tipsters tips.

A complete mad gambler is unlikely to care about such things.
If however you have a more investor style attitude to your betting
ROI figures give you a very good measure as to whether a method is worth following or not.

Let’s do a few quick examples.

Example 1:

Assume you place 100 bets of £100 each

The total you have invested is 100 * £100 = £10,000

For arguments sake let’s say your bets do well and the total return to you is £12,000

( ie £10,000 original stake and £2000 profit )

Your Return on Investment ( ROI ) is therefore £12000 / £10000 = 1.2

Normally this is expressed as a percentage

As a percentage 1.2 is 120%

Example 2:

This time let us assume the betting has not been so good and has lost some money.

Again we have 100 bets of £100 each for a total investment of £10,000

The return this time is less than staked.

We only get £7000 back.

So ROI = £7000/£10000 = 0.7

Or expressed as a percentage 70%

From the above you can see that the breakeven mark is at the line of 1.0 or 100%

ROI above 100% is good
Below it is bad

Profit on Turnover

POT or Profit on Turnover is an alternate measure of betting profitability.

Here we look at net profits as opposed to net return   ( return includes original stake )

Using the same data from the two examples above

1 – POT = £2000 / £10000 = 0.2 or 20%

2 – POT = -£3000 / £10000 = -0.3 or -30%

Note how when using POT 0% is the line of breakeven.
Also note that POT can be positive or negative.

Horse Racing Stats For Saturday

It always helps to understand the past when betting on horses.

Below are a few interesting facts for Saturday’s racing.

These are just a tiny tiny sample from the member message over at

Positive Stat

Pegasus Lad   (1:50 Sandown)      Mark Johnston – horses stepping up in trip from 1m or less and tackling at least 1m1f; SR 20.6% ROI +23.8%

Negative Stat

The Two G’s   (5:50 Lingfield)       Poor sire stat – Mark of Esteem 2yo non handicaps over 5f SR 3.3% ROI loss -71.3%

SR = strike rate

ROI = return on investment
