One of the more popular questions I receive on my podcast is what cadence should I ride at. There is a lot of evidence and success for athletes with a high cadence and also a lot of evidence and success for athletes with a low cadence.
To make things as simple as possible, I would follow this.
- Ride at your natural cadence.
- In a race simulation session or looking back at past races, analyse the data and look at where can you improve.
Below is a cadence fade chart for both Ironman and half Ironman. For example if an athlete is doing a Ironman and the athlete does most of the race with a cadence of 90rpm and in the last 30min of the race the cadence drops to 81rpm, this will show a fade of 10% showing that the athlete needs to either change their cadence or look at ways to limit the cadence fad towards the end of their race.
There could be a number of reasons why an athlete sees a cadence fad and may not be the wrong cadence.
I have also added a power fade here as well to help when you analyse your training/race data.
