This week the Australian Swimming Trials have brought fast swims, most notably a 50 free Australian Record by Cate Campbell in the with a blistering time of 23.79. From my research, this is the 4th fastest 50-free of all-time and a 50 free Australian Record (breaking her own record).
For those who haven’t followed one of our analyses, these analyses are for fun and to spark debate. There are some inherent flaws in this race analysis:
- Videos are taken from YouTube videos (often with subpar angles)
- There are analyzed with Kinovea
Let’s break down the new 50 free Australian Record by Cate Campbell. See the recent Caeleb Dressel fastest 100-yard breast race analysis.

Cate Campbell is ON SONG!

50 Free Australian Record Analysis
First 25 Meters
First 15 Meters
With a 0.75 s reaction time, Campbell doesn’t get off the block well. However, she is able to break the surface of the water at 3.8 seconds and hit the 15-m mark at ~5.8 seconds. She only takes 4 strokes to this mark. She covered this distance in ~2.5 m/s.
15 Meters – 25 Meters
Cate took 9 total strokes over the next 15 meters. She covered this length in 4.9 seconds at a velocity of ~2.0 m/s. Her distance per stroke was 1.1 meters/stroke.
First 25 Meters Analysis
Taking the first half of the race in ~10.7 seconds, she had an overall velocity of ~2.3 m/s. She took 13 strokes over this length.
Second 25 Meters
25 Meters – 35 Meters
Maintain her consistency, Cate takes another 9 strokes over this leg. However, she is beginning to lose speed, taking the next 10-meters 0.2 seconds slower, at 5.1 seconds. Her velocity drops below 2 m/s to ~1.9 m/s, while her distance per stroke remains at 1.1 meters/stroke.
35 Meters – 50 Meters
Into the finish, Campbell closes the last 15-m in ~8.0 seconds at a velocity of 1.8 m/s. Her DPS increases to 1.15 meters/stroke, as she is unable to maintain her stroke rate. Her stroke count was 13.
Second 25 Meters Analysis
Her second 25 meters she took 22 strokes and had a ~13.1 seconds.
50 Free Australian Record Analysis
Cate was able to go a 50 free Australian Record with a remarkable 23.79 seconds.
Most of this is attributed to Cate’s:
- Great distance per stroke.
- Consistent distance per stroke and speed.
- Low stroke count.
Theoretical Improvements for Cate
Time for some fun, how can Cate improve her 50 free Australian Record?
Well, there isn’t as much to analyze in the 50 free, but there are a few aspects for Cate to improve.
- Improved Reaction Time?: I hate to suggest it as reaction time doesn’t correlate with a faster time to 15-m. However, she is nearly 0.1 seconds slower than the field off the block. She is able to hit the 15-m mark with the field, but I can’t help but wonder … if she can keep her start the same and get off the block a few hundredths faster…
- Maintain Stroke Rate on Last 15-m: Perhaps if Cate can maintain her stroke rate on the last 15-m, then she may be able to finish with the same velocity as her previous 10-m (25-35-m). Clearly, this is easier said than done, but many of the top sprinters are able to “charge the wall” and finish with similar velocity as their previous marks.
Anyway, it is great to see Cate back and swimming faster than ever. Hopefully, she can continue to improve and swim well in her upcoming races to push the World Record.
