1. Compare charts
After a training run, I head straight to my running performance stats and select “visualize your run performance.” Here I get a detailed breakdown of my run, and the option to “compare charts.” This allows me to choose different stats and see how they affect each other — for example, I can select just my pace, heart rate and stride length. This can help me get an idea of how hard I’m working when I take bigger or smaller strides. The idea is for my body to not work so hard, so I can preserve my energy (especially for long trail runs when I need it). If I’m noticing a trend where I’m taking longer strides and seeing my heart rate increase and pace decrease, that’s something I can try and pay more attention to in training.
