Week 01 Run 01
20 min walk-run · run 2, walk 1
Twenty minutes on the clock. Run two, walk one, repeat until the twenty is done. That is a complete first session, so do not add to it. Easy means you could hold a conversation the whole way. Do it three times this week, then follow the first month on one of the measured loops.

Bars are the whole session to scale, warm-up to cool-down. Paces assume a 5K around 21 minutes; start at the slow end, or let the planner rewrite them for you.

An example block for a runner whose easy runs sit around 5:30/km: 20 to 31 km a week, every kilometre counted from the runs. New to running? Start at run 01 above, and the planner sets your own volume.
