MaraPace: AI Marathon Coach

Your pocket marathon coach. Get a personalized week-by-week plan, target paces and heart-rate zones for your goal time — plus AI feedback after every run.

MaraPace is your AI-powered marathon and half-marathon coach. Tell it your goal finish time and race date, and it builds a personalized week-by-week training plan with exact target paces and heart-rate zones for every session — then reviews each run and tells you what to adjust.

BUILT AROUND YOUR GOAL • Set a goal time (e.g. half 2:00, full 4:30) and MaraPace derives your easy, tempo, interval and long-run paces. • Enter your race date and your plan auto-scales to the weeks you have — 6 to 32 weeks. • Every workout has a clear structure: warm-up, main set, cool-down, target pace and heart-rate range.

AN AI COACH THAT ACTUALLY RESPONDS • Log a run and get instant, specific feedback on pace, effort and heart rate. • Ask follow-up questions — "legs are sore, can I run tomorrow?" — and get a real answer. • Weekly AI reports summarize plan-vs-actual and what to focus on next.

TRAIN WITH PRECISION • Heart-rate zones personalized with the Karvonen method (optional measured max/resting HR). • Apple Health import — pull in your recent runs automatically. • Plan-vs-actual and pace-trend charts track your progress.

STAY MOTIVATED • Follow friends, compare weekly mileage and cheer each other on. • Daily reminders keep you on schedule. • Fully bilingual: English and Simplified Chinese.

Training paces and heart-rate guidance are grounded in established running science (Tanaka, Karvonen, Daniels' VDOT). MaraPace is a training aid, not medical advice — listen to your body and consult a professional before starting a new program.
