The Truth About Cadence Part 3

Having looked at sprinters, our attention now turns to the middle distance runners. Traditionally competing in the 800, 1500 and perhaps the 3,000m; the research hit a problem – World Athletics didn’t report on any of these races at the 2017 World Championships. Fortunately, as I was writing this series of posts, the 2024 European Championships in Rome were taking place and so, I had to be like Jack Daniels, and do my own bit of counting. Using the televised footage I was able to replay certain sequences of the races to get an idea of the cadences involved.

I watched each race through in its entirety to get an understanding of how it played out and identify which runners were near the front of the pack and of whom I could get an unobstructed view. Often the TV director regularly switched between close-ups and long shots of the race, on different runners and by necessity switching to different cameras positioned around the track. Typically I managed to count the paces for 15-20secs and then multiplied that up to get a value per minute. Being manually calculated in this way, I could be out by a few steps per minute but we’re interested in getting a rough idea of the numbers involved – not doing an exact scientific breakdown!

Having identified one runner for each race I then did a lap-by-lap breakdown for them. This was necessary because longer races can start off slowly, building the pace and then finishing in a mad dash to the line. We might expect different cadences as the race pace picks up or lulls. With only one runner analysed per race it’s by no means a perfect look at the cadences we see but it’s an indication.

800m

The men’s final was won by France’s Gabriel Tual in 1:44.87 and it was his data I collected for the two lap race. The first lap took 53sec which is around 3:30/mile and his cadence was 197spm.

The 2nd lap was marginally quicker at 52sec but in the home straight Tual put in a big sprint finish and this was what I measured. I watched and rewatched the video multiple times as my first calculation had him registering a cadence of 234spm, a second viewing it was 224 and I finally settled at 228spm. This is a significantly higher value than the rest of his race but what we expect when runners sprint.

For the women’s 800m, I used Great Britain’s Keely Hodgkinson as my subject. She’s run the fastest time in the world this year and is in with a chance of winning gold at the Paris Olympics. She actually won the gold at these championships, but I recorded her cadence in the semi-final where she ran 1:58.08.

The first lap of the race was run in 57.6s followed by a slightly slower second lap of 60.4sec. The cadence for the first lap was 202spm, rising to 206spm on the second. This might seem strange given the second lap was slower but from 400-600m the runners slowed before Keely accelerated away on the final bend where I measured her second lap cadence.

What we can see from both the men’s and women’s race is it’s not unusual for 800m runners to have cadences of over 200 during the main race. And with speed being a key requisite for its runners, it’s no surprise to see that a runner like Tual has the ability to hit even higher cadences.

1,500m

Norway’s Jakob Ingebrigtsen is arguably the star of male middle distance track racing at the moment. It was his data (table 1) I captured during the heats of the men’s 1,500m event. Due to the race being a 300m lap followed by three full 400m circuits, it is difficult to know where to place the short ‘lap’ when trying to ascertain split times.

Lap 21864:09
Lap 31933:49
Lap 42083:37

Being a heat, it was an easy race for Jakob and he seemingly jogged off the start line such that everyone was ten metres ahead of him. From there he sat at the back of the pack avoiding trouble until the final 300m when he overtook everyone and finished first. We can see his cadence is steady around the 186-194 mark while he was at the back and then when he accelerated it went over 200.

The women’s final where I obtained the cadence data was run even more tactically with the first two laps at a relatively sedate pace before it began to wind up and Ireland’s Ciara Mageean came through to take the gold. Even though the pace was a little slower we see that the cadences were all lower throughout.

So that’s cadence for middle distance runners. Bear in mind, the data provided here is limited to four individuals – Gabriel Tual, Keely Hodgkinson, Jakob Ingebritsen and Ciara Mageean. There’s strong reason to believe its representative for all elite runners but there will be some individual variance with others.

If this data shows us anything in particular it’s that the faster you run – the higher your cadence. Intuitively that makes sense. We see the “magic 180” figure is being adhered to at paces around 4:30/mile and when middle distance runners break into a sprint they go over 200spm but never approach the cadence of the short sprints.

In the next post – we will look at the cadence of long distance runners. Most recreational runners only compete in these types of races so it should provide interesting data. Click here to go to it.

Olympic thoughts – Fast women

Tuesday afternoon, day eleven of the 2021 Tokyo Olympics, gave me an opportunity to look at world-class 800m running. It was the final of the women’s competition and from a British perspective there was huge interest. Three women making the final brought back memories of the 1980-84 Olympics when British men ruled middle distance running with Seb Coe, Steve Ovett, Steve Cram and Peter Elliott at the top of their game.

Racing two laps of the track, beginning in lanes with a standing start, runners break at the end of the first bend so that by the 200m mark they’re running together. I’d estimate the time for the first 200m was 27.7 seconds, the next 200 was a relatively slow 30.12s to give a first lap of 57.82s. The second lap was 57.39s (29.33s + 28.06s) for a winning time of 1:55.21

The race was won by USA’s 19-year-old Athing Mu and she is something of a sensation, as is silver medallist Keely Hodgkinson who is the same age. There’s a possibility they could be pushing each other to faster times for the next decade. There was almost a bronze medal for Britain’s Jemma Reekie but she was beaten on the line by Raevyn Rogers; and Britain’s third runner Alexandra Bell finished 7th out of eight.

This was one of the faster 800m finals but they’re usually won in the 1:55-57 range. From what I’ve learned about running the 800 the first lap is typically faster with the second about two seconds slower; but today was a negative split. The slower second 200m was the culprit and would have been part of Mu’s gameplan as she has run 49.57sec for the 400m. She would have been confident that if she could be leading at the bell, she’d be able to outpace the rest of the field over the second lap. Consequently she took the lead as the pack formed on the back straight of the first lap and then imperceptibly slowed the pace. She never relinquished first place and went on to win by two-thirds of a second which is huge at this level.

There is nothing slow about these women. The pace of the winning time is 3:52/mile (2:24/km) with the average per 200m being 28.8 secs. If they could do a parkrun at this pace, they’d be done in twelve minutes. But remember, as I wrote in my article on True Speed, top speed is a lot higher.

As it happened the women’s 800m final was followed twenty-five minutes later by the women’s 200m final and gives us a good chance to compare. Having already won the 100m title with the 2nd fastest time in history, Elaine Thompson-Herah was now going for a “double double”. She didn’t disappoint as she went on to run the 2nd fastest 200m time in history at 21.53s – that’s six seconds quicker than the fastest 800m split.

By comparison, the PBs of the three British women for 200m aren’t close. Alexandra Bell ran 25.74s in 2016, Keely Hodgkinson ran 26.5s in 2018 and Jemma Reekie a wind-assisted 27.3s in 2015. These times are not poor by the standards of the rest of us but, as you can see, they’re a long way off being close to competitive over a sprint distance. There’s a genetic element to what event you’re best suited to, but also note how the longer the distance you run, the more you trade off speed for endurance. Mu’s two laps of fifty-seven seconds were significantly slower than her 400m ability.
