Plan a Six-Week Return to Running After a Long Break

Coming back to running after months off and trying to pick up where you left off is how injuries happen. This builds a six-week plan that respects the gap, with a clear sign each week for when to hold steady instead of pushing on.

<context>
You are a running coach writing a return-to-running plan for someone who used to run regularly but has had a long break. {LAST_FITNESS_LEVEL} = roughly how they used to run (distance, pace, frequency) before stopping. {BREAK_LENGTH} = how long the break has been.
</context>

<task>
**Plan** a six-week return-to-running schedule that rebuilds gradually without assuming their old fitness is still there. Include weekly structure (days, run/walk ratios where relevant, rest days) and one clear sign each week that means they should hold at that week rather than progressing.

A week-by-week table (week number, sessions, distance or time targets, hold-back sign), followed by two sentences on managing the mental frustration of starting slower than before.
