About Summit

Stop stitching together a spreadsheet, a pace chart and a Pinterest checklist. Summit is a single training planner built for runners training for anything from a 5K to a 50K. Enter your race date and current mileage, and it builds a full week-by-week plan — base, build, peak and taper — with progressive mileage, automatic cutback weeks, and your long run scheduled on the day you choose. Enter one recent race result and it calculates your real training paces using the Jack Daniels VDOT method — the same science behind serious coaching plans, not a generic "race pace × 1.1" guess.

What's inside

• Training Block Builder — full periodized plan (base → build → peak → taper) for 5K, 10K, Half, Marathon or 50K, tailored to your experience level, weekly mileage and available training days. Race day always lands exactly on your chosen date.
• VDOT Pace Calculator — one race result predicts your equivalent times at every distance and sets your Easy, Marathon, Threshold, Interval and Repetition training paces automatically.
• Even-Split Calculator — enter any goal time and get mile-by-mile checkpoint splits instantly.
• Training Log — log every run with auto-calculated pace and effort (RPE), and track compliance against your plan automatically.
• Shoe Rotation Tracker — log mileage per shoe with retirement warnings before they wear out under you.
• Race-Day Toolkit — a temperature/wind-based outfit guide, a fueling & hydration calculator scaled to your finish time, and a fully editable, printable race-day checklist.
• Dashboard — countdown to race day, this week's workouts, an 8-week mileage trend, and plan compliance at a glance.
• Built-in Help tab with a getting-started guide, FAQ and glossary — plus full JSON export/import for backup.

Why it beats free alternatives

Most free pace calculators use a single flat multiplier for every training pace. Summit uses the actual VDOT formula, so your paces are internally consistent with real exercise physiology. Most free training plan generators hand you a static PDF; Summit builds a plan around your mileage, your days and your race date, then tracks your actual compliance against it.
