Personal Best Running

Stop guessing your training. Start running with science. Personal Best Running builds your personalized training plan using the Jack Daniels VDOT system — the same methodology trusted by Olympic coaches and elite runners worldwide. Just enter your race goal, current fitness, and training availability. Everything else is handled for you.

Here's what you get:

• A Complete Periodized Training Plan — Your plan is structured into scientifically-proven phases: Base → Build → Peak → Taper → Race. Each week balances volume, intensity, and recovery with the right mix of runs.
• VDOT-Based Training Paces — No more "run by feel" ambiguity. Every session shows you the exact pace target calculated from your personal VDOT (aerobic fitness index). Paces adjust as your fitness improves — you always train at the right intensity, never too hard, never too easy.
• Athlete Profile & Progression — See your predicted race times across every standard distance. Track your runner level on a progression bar, understand how far you are from the next level, and see exactly what it takes to get there. Multi-distance predictions show you're not just training for one race — you're building fitness for life.
• Seamless Calendar Export — Sync your entire training program directly to Apple Calendar. Get day-by-day workouts complete with purpose-built notes explaining the why behind your training, alongside exact distances, paces, and structured sets
• Export to PDF — Prefer a physical copy? Export your full training calendar to a clean, readable PDF. Print it out, stick it to the fridge, and cross off the days as you crush them.
• Methodology Guide — An in-depth reference explaining the science behind VDOT, the 5 training zones (E/M/T/I/R), RPE, periodization, volume rules, and more. Learn why your plan works, not just what to do.

Why this app is different: Most running apps give you generic templates or AI-generated variations. Personal Best Running is built on the Daniels VDOT system from Daniels' Running Formula — the gold standard in running coaching since 1979 — combined with evidence-based research in endurance training, periodization, and tapering. Your plan isn't just a template with your name on it. It's built from scratch using your race distance, target time and current performance.

For every level. Whether you're running your first 10K or chasing a Boston qualifying marathon, the plan scales to your fitness. The VDOT system is inherently personal — it meets you where you are and takes you where you want to go.

No subscriptions. No guesswork. Just science-backed training that works.
