What it is

Built for First-marathoners and PR-chasers training 12-20 weeks for NYC, Boston, Berlin, Chicago, London, or local 26.2.. Train. Taper. Finish. — a browser-native interactive dashboard that lives in a single HTML file, no installation required.

The Marathon Training Dashboard fixes that in one HTML file. Open it in Chrome, type in your last long run, and watch a complete race operating system come to life: a 16-week training plan that knows where you are this week, a mileage log that rolls up every shoe and surface, a race-day prep checklist that survives taper-week anxiety, and the feature no static plan offers, a Race Pace Calculator that ingests your recent training paces and projects your finish time and per-mile splits by heart-rate zone.

Every keystroke autosaves to your browser. Close the tab, reopen tomorrow after your 5 AM run, your log is exactly where you left it. Export a JSON backup any time you want to keep a copy or share with a coach.

★ EXCLUSIVE ZONE

The Race Pace Calculator is built into Tab 5 and is the reason this product exists. Drop in your last three long-run paces, your goal time, and your aerobic threshold heart rate. It computes your target marathon pace, projected finish time, recommended pace per mile, and a printable pace band split by HR zone. You walk to the start line knowing the number.

WHAT’S INSIDE (5 tabs)

Overview, your weekly dashboard. Days to race, total weekly mileage, longest run this cycle, projected finish time, plus a 16-week training game plan.
Weekly Log, the streak engine. Date, miles, pace, route, shoe, surface, HR avg, RPE, plus a per-week mileage rollup.
Training Plan, the schedule. 16 weeks pre-loaded with easy, tempo, long, recovery, race-pace, and rest days, customizable per buyer level.
Race Day Prep, the checklist. Gear, nutrition, taper-week protocol, course notes, sleep target, alarm time, pre-race breakfast.
Pace Calculator ★, the finish line. Recent paces in, target marathon pace and per-mile split sheet out, broken by HR zone.
