Snel vs
Kaizen

Both data-driven. Only one builds your plan.

Kaizen is a smart training app that gives you weekly volume and intensity targets, then lets you decide how to fill them. It's a flexible, data-driven approach. Snel takes a different path: it generates a complete structured plan with daily workouts, specific paces, and periodised phases, then adapts it as you go. Both are data-driven. Only one tells you exactly what to run tomorrow.

Flexible structure

Kaizen gives you weekly volume and intensity targets without prescribing specific sessions. If you prefer deciding what to run each day, this flexibility is a genuine advantage.

Race prediction accuracy

Kaizen uses your training data to predict race times with solid accuracy. Their model is well-regarded in the running community for giving realistic estimates.

Minimal friction

No workout-by-workout logging needed. Kaizen reads your Strava data and adjusts your targets automatically. It's about as low-effort as training guidance gets.

Full structured plans

Snel tells you exactly what to run every day: workout type, distance, pace zone, warmup and cooldown. No guessing, no decision fatigue. Open the app and go.

Warmup and cooldown drills

Each workout includes specific warmup and cooldown routines. Kaizen focuses on the run itself; Snel covers the full session.

Coach personality

Choose a coaching style that matches how you train: Supportive, Motivational, or Clinical. Kaizen's guidance is purely numerical.

Free to use

Kaizen costs around €80/year. Snel delivers structured plans, VO2max zones, and weekly adaptation on a free tier. Pro (€49/year founder price) adds integrations and advanced analytics.

Injury prevention

Body-check prompts, load monitoring, and automatic volume reduction when fatigue signals accumulate. Snel actively works to keep you healthy.
