Plain answer
Anchor the run to something that already happens, prepare the first two minutes in advance, and judge success by the week rather than a flawless streak.
Keep the cue stable
The trigger might be finishing work, school drop-off, sunrise, or changing clothes. The exact route can vary while the cue remains familiar.
Lower the starting friction
Shoes, weather check, route, and minimum session can be decided before the moment when motivation gets a vote.
Review without punishment
At week’s end, ask what blocked the run and adjust the structure. Do not repay a missed session with unsafe volume.
