In our research, we found that runners are divided on which direction is more intuitive for pace charts, and they hold those opinions strongly. We received volumes of feedback on the redesign, and the axis direction of our pace charts was a hot topic of dispute.
Internationalization is the kind of problem whose solution is comparable to replacing the wheels of a moving train – it’s not acceptable to slow down the product development cycle while it is happening.

Running uphill requires more effort than running on a flat grade, so GAP adjusts pace to be faster than the actual running pace. Similarly, GAP is slower than actual pace on downhill terrain. This post discusses improves we have recently made.
