In the second part of this two part article, part one available here, Jon Shenton digs into Mark Johnston's performance record in search of profitable betting angles. Here he looks at older horses as well as Johnston's favourite course.
Roughly 70% of Johnston’s runners are 2- and 3-year-olds so perhaps there is less focus on his older horses. The vast majority of these more mature runners’ activity, as you might expect, is in handicaps (all bar 150 or so runs, which have a losing ROI of c.25% at SP). It makes sense, then, to concentrate on the journeyman handicapping cohort for further review.

|Age restriction||Runs||Wins||Win%||P/L (SP)||Place%||ROI (SP)||P/L (BF)||ROI (BF)||A/E|
The table above shows the split of the runners in the two age groupings for eligible handicaps, and it is apparent that a Johnston 'older horse' in a 3yo+ handicap is worth a second look. In fact, if we split things down further by age of runner, we can see that the focus ought to be on 4- or 5-year-olds in 3yo+ handicaps. The table below illustrates the breakdown by age:

|Horse Age||Runs||Wins||Win%||P/L (SP)||Place%||ROI (SP)||P/L (BF)||ROI (BF)||A/E|
Horses aged six and older have a record of 1 win from 66 races, losing 95p in the pound over time. In fact, checking the record of Johnston 6-year-olds-plus in all handicap races (including the 4yo+ category) makes for ugly reading with just 13 wins from 155 runs, something of a red flag when seeing horses such as Final or Watersmeet taking their place in the stalls next time.
The 4/5-year-old performance also comes with a major health warning sadly, in that there are a couple of long odds winners buried in there - at 66/1 and a couple of 33/1 shots too - which are enough to inflate the profit level significantly without negating the angle entirely. Ordinarily these could and probably should be ignored: it is not generally good policy to rely on a few Hail Mary’s to land so I’d probably take these out of the equation. That may be a risk averse mindset but I have a preference for higher strike rates, and more reliable data-driven wagering.
That extra reliability can be attained by trying to establish which may be the better quality horses within the data. In very general terms the higher the weight carried (or ranking of horses' official rating in the race) the greater the chance of that horse winning in a handicap.
If we analyse these 4/5-year-olds in terms of position in weights (excluding jockey claim) we get the following breakdown:

|Pos in weights||Runs||Wins||Win%||P/L (SP)||Place%||ROI (SP)||P/L (BF)||ROI (BF)||A/E|
As can be seen, horses in the top three in the weights are worth closer scrutiny, and I suspect that Johnston, with his vast army of young horses, knows better than most how to place his slightly older fleet to maximise probability of a strong run.
Mark Johnston’s positive training record at Goodwood is well documented: 53 victories over the past six years from 355 runs, with a pretty healthy 14% profit if you backed every single one at SP.
There are some cautionary tones to heed, however: during 2018 we’ve seen the best strike rate (18%) but the worst wagering return since 2013, with losses of 19% at starting price. Few braindead simple approaches last very long, and perhaps the market has wised up and adjusted, or perhaps it is genuinely a case of the shorter priced horses landing (average price of winners in 2018 is approx. 5/2 compared to the overall 13/2 or thereabouts). One to keep an eye on as usually Johnston's second- and third-string entries can be relied on to hit their mark during the season, and especially at the Glorious - sorry, Qatar Goodwood Festival - meeting.
Overall, there are not many Johnston horses that go to Goodwood at huge prices. Indeed, only 23 have gone off with an SP of 20/1 or bigger, and not a single one has even hit the frame. It seems sensible to be apprehensive of any horse at these prices, with the yard apparently knowing more about what is expected than many in the betting media and indeed public.
Another consideration when evaluating trainers is checking how their runners perform in relation to their layoff: how many days they have been off the track. The table below shows the breakdown of all Johnston's Goodwood runners split by the last time the horses stretched its legs in competitive action.

|Days Off||Runs||Wins||Win%||P/L (SP)||Place%||ROI (SP)||P/L (BF)||ROI (BF)||A/E|
It could be argued that the data alludes to the fact that Johnston has a plan in mind when sending horses to this particular corner of the Sussex countryside, getting them there in peak condition through a relatively recent tuning run, 11-25 days looking optimal. Backing in line with this improves the strike rate to nearly 20% and a SP profit level of 64%. Horses that haven’t run for more than 25 days have a rather lean record of three wins from 69 runs (not all data included in the table) so should be considered unsympathetically based on that evidence; evidence which is supported by the fact that Johnston famously keeps his horses fit on the racecourse rather than at home, so greater absences may be assumed to infer an issue of some sort.
A fair amount of rummaging around the Johnston battalions since 2013 has kept me very busy, although it has still left a feeling that I’m just scratching the surface. Hopefully there are a few angles of interest, or at least some food for thought for development of your own approaches. As ever with analysis of this nature sample sizes can be small, but that’s the beauty and challenge of it all: trying to figure out if these snippets of data and patterns can be used as a basis to bet in the future, in this case to pinpoint some of Johnston’s next 4194 winners!
Possible angles and betting opportunities (from part one and two of this article)
- Johnston First Time Out 2-year-old fillies over 5-6.5f, especially during the months of May to August
- Previous 2yo winners in novice races if they have had a recent run throughout spring and summer
- Winless 3yo runners with five or fewer career runs in 3yo handicaps
- 4/5-year-old runners in 3yo+ handicap races, particularly if they are in the top 3 official ratings / weights
- Goodwood runners shorter than 20/1 that have had a recent run (ideally 10-25 days)
- Tread carefully with Johnston runners in nursery handicaps and any older horse (6+) running in a handicap.

POST SCRIPT 3rd September 2018: My mate Ben Aitken has taken the Mark Johnston theme and run with it a little further, looking at performance by run style. Regular followers of Geegeez Gold pace content may be able to guess at the findings, but they're pretty striking all the same, and can be checked out here.
