Paceflow: AI Running Coach

Paceflow

About this app

Train smarter, not harder. Paceflow generates a personalized running plan based on YOUR personal best, current weekly distance, and training days — with exact paces for every single workout.
Enter your PB and Paceflow instantly calculates all your training zones: easy, tempo, intervals, race pace, recovery. Set your goal distance and target time, and get a plan built specifically for your fitness level.
YOUR PLAN ADAPTS TO YOU:
Your training plan isn't static — it responds to how you actually train. Skip a workout? The plan adjusts, making the next sessions easier to get you back on track. Ran more than planned? Paceflow recognizes your effort. Reschedule workouts freely — move them to days that work for you. The plan evolves with your life, not against it.
PERSONALIZED FROM DAY ONE:

Your PB determines all training paces — no generic zones
Current weekly km sets your starting volume — no impossible first week
Number of training days shapes your schedule — 3 days or 6 days, it fits
Goal validation tells you if your target is realistic, a stretch, or too aggressive

Weekly volume charts — see your km trend week by week
Completion stats — workouts done, total distance, average pace
