I often see people say that carbon-plated shoes only really help at faster paces, and I’m trying to wrap my head around that.
For example, a runner who’s “fast” at 5:00 min/km (around a 50-min 10K) has a completely different running economy than someone who’s fast at 3:30 min/km (around a 35-min 10K).
From my own training, running at 3:30 min/km feels almost like a sprint — especially during strides — and I feel like I’m putting a lot more force into the ground with each step. Meanwhile, faster runners can cruise at 3:30 min/km with much more efficiency.
That got me thinking:
If I’m running at 3:30 min/km, am I using the carbon plate more than a faster runner at the same pace?
Do I get the same level of benefit if I’m working just as hard (relative effort) as a faster runner?
And finally, would heavier runners see more benefit at slower paces since they’re applying more force with each step?
