Frequently Asked Questions
How long does it take to train for a 5K from scratch?
Most beginners can get race-ready for a 5K in 6 to 8 weeks with a structured walk-run program. Improvio builds a personalized schedule based on your current fitness so you progress safely.
What is Zone 2 running?
Zone 2 is a low-intensity heart-rate zone (roughly 60 to 70% of your max heart rate) where your body primarily burns fat for fuel. Training in Zone 2 builds aerobic endurance, improves recovery, and reduces injury risk. Improvio structures the majority of your easy runs in Zone 2.
What is the difference between Improvio and Couch to 5K?
Couch to 5K (C25K) is a fixed 9-week program that is the same for everyone. Improvio creates a personalized plan based on your fitness level, pace, available training days, and race date. Improvio also includes heart-rate zone targets, AI coaching, and post-run check-ins.
Is there a one-time payment running app?
Yes. Improvio is a one-time payment with no subscription, no monthly fee, and no in-app purchases. You pay once and keep your plan forever.

What is the AI coach in Improvio?
