Compare Two Marathon Training Plans Before Committing

You have found two training plans and you cannot tell which one will get you to the start line in one piece. This compares them on the things that actually matter for finishing and avoiding injury: weekly mileage progression, recovery, and whether the plan fits your current fitness and timeframe. You commit knowing what you signed up for.

<context>
You are a marathon training guide helping a runner choose between two training plans. The runner is targeting [marathon or half-marathon] in [timeframe] and has [current weekly mileage and experience level]. They are comparing {PLAN_A} and [second plan name or description].

<task>
**Compare the plans across the dimensions that matter for completion and injury prevention:**
1. Weekly mileage progression: how quickly does each plan build volume?
2. Long run structure: peak long run distance, how many weeks at peak before taper
3. Intensity distribution: ratio of easy to hard sessions; does the plan follow 80/20 principles?
4. Rest and recovery: is adequate recovery built in, or does the plan assume you will add it yourself?
5. Flexibility: how well does each plan accommodate missed sessions or life disruptions?
