It’s addictive when you’re on training apps like Strava. You’re looking at your graphs and you’re wanting that weekly mileage to be progressively increasing. It’s actually not the healthiest way to do it. You should be striving for consistency.
“If you can run 20km for a few weeks and then build it up to 24km for a few weeks, it’s a much better way of doing it if you want to run long-term. It reduces the injury risk, and you can then add the intensity at the same time. Whereas if you’re trying to add distance and intensity, that’s going to increase your chance of injury.
