Compare the website plans and Run With Hal separately
You do not need to leave Hal Higdon simply to obtain an adaptive plan. The official Run With Hal app describes plans that adjust to experience, schedule and the target race. A downloadable schedule and the app are different products.
Keep a familiar Hal Higdon plan if its starting load, weekly rhythm and explanations work for you. If the problem is a missed session or changing availability, first test how the app handles that exact situation before assuming a replacement is necessary.
Which alternative addresses the missing job?
26weeks.ai is not a one-for-one replacement for every Hal Higdon distance or plan format. Its product focus is a 26-week pursuit toward six supported goals: half marathon, marathon, HYROX, Ironman 70.3, Ironman and 100K. Check the current offer and device requirements before subscribing.
Make the switch decision concrete
Compare one ordinary week and one disrupted week. Write down what is moved, reduced or omitted, and whether recovery remains workable. Retain your training history and choose one plan to govern load; combining both schedules defeats the comparison. Use the marathon-app checklist for the trial.
