I can’t say I ever really cared about my running cadence - I just ran at what felt natural and comfortable. Turns out that is about 166 spm which seems to be the most average cadence out there.
I’ve had many knee issues over the years, but I don’t think I’ve had ITB issues until this year - the big difference there was how sudden it would come on and how debilitating it was. This was not a struggling through thing. I had to stop and walk. Which was an obvious concern for me on longer runs - I did not want to be facing a 10k+ walk/hobble back. So I did take it seriously.
I had a full week off running when I just did knee strengthening instead (I found it frustrating that this happened to me as I have actually taken lower body strength exercises seriously for the past three years) and then four weeks of building up gradually, running on the flat only and working on cadence. Cadence and stride/gait alignment (width) seem to be the recommended changes for ITB. I know I have a bad crossover gait as I kick my own feet sometimes when running, but I feel like it’s harder to consciously change this. Increasing cadence means a smaller and quicker stride and so perhaps because I am more conscious of my feet landing closer together this will actually naturally also push out my gait width.
I felt really stupid when I first tried to increase my cadence. It felt very unnatural, but having a boring out and back flat route was very useful for practising with this. I tried both slow paces with a high cadence and then my natural pace (between 4 to 5 mins per km) at a high cadence as well. I was mostly my own metronome and counted to myself, but some high paced punk (Snõõper) or dance (Ela Minus) does help. After some experimentation I found a smaller step cadence and pace that felt ok. I think it’s actually slowed my pace ever so slightly.
There aren’t many practical steps for increasing cadence (and not increasing pace at the same time), but basically it means intentionally taking smaller quicker baby steps. If you do high cadence running on the spot and then also at a slow a pace as possible then you should find your cadence increase at your natural pace. At times I’ve also found it helpful to think about moving my feet from my glutes as opposed to my knees (i.e. barely moving my knees) and also taking lighter floaty steps (almost skipping). It is 100% worthwhile doing all this on the flat as it’s harder to keep a consistent cadence uphill and off-road.
I have managed to make this change stick. Doing a before and after with my last six runs (i.e. some of my common routes) I’ve gone from an average of 164 spm to 175 spm. I’m happy with this. If I can keep it around 175 that is a decent difference.
