If you're training for a distance other than the half marathon, want the cheapest possible plan, or you're experienced enough to self-correct when a plan doesn't fit your week, an app is a reasonable choice. Runna is well-built for that. It's not a bad tool, it's just a different tool than a coach.
If you've used an app before and hit a wall you couldn't explain, if you want someone to actually look at why a session went badly instead of just logging it, or if the half marathon specifically is your target and you want a plan built around its pacing and taper (not a marathon plan with weeks chopped off), that's what a coach does that an algorithm can't.
Yes. Runna is an app that generates a training plan and adjusts it algorithmically. RunLetters Half Marathon Coaching is a real coach, Caroline Claassen, who builds and adjusts your plan directly, runs live group sessions, and answers your training questions herself. It's the right alternative if you want a person behind the plan, not just an app.
Runna's plans are generated and adjusted by algorithm based on the data you log. A real coach reviews your training, asks why a session felt hard, and adjusts your plan based on judgment, not just logged numbers. Runna also covers every running distance; RunLetters Half Marathon Coaching only trains the half marathon, so every plan is built around that one distance's pacing and taper logic.
