About Paceriz: AI Running Coach
Should you run the plan today—or take a rest day? A plan is only the starting point. Paceriz reads your synced run data, assesses your current fitness, then reviews what you actually ran each week to adjust the following week—and explains the main reasons behind the plan. [It remembers yesterday's workout] Finished intervals yesterday? Open the app today and see why an easy run is on the schedule: to let your heart rate settle. The home screen also shows changes in your fitness metrics and your projected finish time for your target race. [Your plan adapts to you] Set your target race and the days you can train. Paceriz maps out each week: easy runs, intervals, tempo runs, and long runs; how far to go; and the appropriate pace or heart-rate range. Each week, it reviews what you actually ran before deciding whether to add volume, hold steady, or ease back for a week so your body can absorb the work. [Plans that explain why] Why is this week set up this way? Why is it lighter than last week? Your plan and weekly review explain the main reasons behind the schedule, so you don't have to guess. [See yourself getting stronger] Fitness measures such as aerobic endurance and speed endurance update as you train. Your projected finish time adjusts with your latest training data; mileage accumulates automatically, and eligible runs can set new personal records. [When life changes, talk to Rizo] Sore legs, poor sleep, or a sudden work trip? Tell Rizo, your coach. Rizo can suggest plan adjustments, which take effect only after you confirm. This feature is available with a subscription. [Keep recording your usual way] Sync your training from Garmin Connect or Apple Health. Runs recorded on Apple Watch can also be imported through Apple Health. Connect Garmin to send workouts to your watch and follow them as you run. [Who it's for] • You're training for a half marathon or marathon and want a plan that adapts to your current fitness • You want a personal record but aren't sure when to add mileage or take a rest • You're starting out and want to build steadily from a 5K or 10K Eligible new users get a 14-day free trial with full features, including weekly reviews and next-week plan adjustments.
