About Rai
Rai is a Brazilian sports-technology company that uses artificial intelligence to create and adapt personalized running plans for every runner.
We combine sports science, real training data, and artificial intelligence to deliver a running coach that fits in your pocket — from your first 5K to the marathon.
What Rai is
Rai is a Brazilian digital platform built by runners and engineers to solve a real problem: generic training spreadsheets don't evolve with the runner. Rai does.
We serve runners of every level — from beginners who have never run 1K to marathoners chasing a new personal record.
What sets Rai apart
Rai brings adaptive artificial intelligence — not just automated spreadsheets — to amateur running training, adjusting upcoming workouts based on each runner's actual execution.
- AI that adapts the plan week by week based on actual execution, not a fixed formula
- Direct integration with Garmin, Strava, Apple Health, and Health Connect for automatic workout analysis
- Science-based methodology (training zones, periodization, the 80/20 principle)
- 24/7 coaching chat for questions, adjustments, and feedback
What Rai does
- Creates 100% personalized training plans based on your goal, level, and schedule
- Analyzes your synced Garmin, Strava, Apple Health, or Health Connect activities in real time
- Automatically adjusts the upcoming weeks based on execution and feedback
- Offers a 24/7 coaching chat for guidance on pacing, recovery, and injuries
Who Rai is for
Rai is for anyone who runs or wants to start running: from a first 5K to marathon preparation, including runners focused on weight loss, health, or performance.
