Ground Contact Time (GCT) is an essential indicator of your running efficiency
Ground contact time (GCT) is the most straightforward metric to understand. It is the time the foot spends on the ground, from initial contact to terminal contact. This metric is measured in milliseconds (ms). An explanatory video of GCT is available here.
In an analysis of 50 customers, where more than five shoes were analysed, the GCT varied by an impressive 11% (Percentage Difference)
RUNRIGHT-3D measures GCT, helping you make informed decisions tailored to your customers’ needs.
GCT is an essential indicator of your running efficiency and biomechanics.
Efficiency: A shorter GCT generally means you are running more efficiently, spending less time on the ground and more time propelling forward.
Injury Prevention: Longer GCT often indicates overstriding or low cadence, which increases stress on the lower back, hips, knees, and ankles.
Performance: Elite runners have shorter GCTs, which helps them run faster. Reducing your GCT will improve your speed and overall performance.
How do shoes affect GCT?
The image on the left exemplifies how variable GCT can be between shoe designs.
It’s the same runner at 9 kph and 14 kph. Running at 9 kph, the Saucony Endorphin Elite displayed the fastest GCT. However, at 14 kph, the Adidas Ultra Boost had the faster GCT; nonetheless, this particular runner did not like the Adidas’s dynamic fit.
All in all, GCT depends on shoe design, pace and the individual input of the runner.
Don’t forget that strength and conditioning can also improve GCT. Comfort and fit are personal choices.
It is worth remembering that shoe choice can affect GCT by an impressive 11%.
