These are upper limits, not targets. Repeat a week or step back if you feel worn down, sore in one spot, or short on sleep.

The 10% rule is a coaching rule of thumb, not a proven threshold. Runners on low weekly totals can often add a bit more; runners on high totals usually add less. Use the slider to match.

Weekly total is only half of it. Avoid a single long run that is much longer than anything you have done in the past month.
