FIT-DB is an integrated triathlon training management platform that helps athletes plan, track, and analyze swim, bike, and run workouts using evidence-based training principles.
Everything you need to manage your triathlon training
Build structured training schedules using periodization principles. Organize your training across base, build, peak, and taper phases for optimal race preparation.
Record every swim, bike, and run session with detailed metrics including distance, duration, heart rate, RPE, and custom notes. Track your progress over time.
Visualize training load, intensity distribution, and fitness trends with interactive charts. Monitor your training stress score (TSS) and weekly volume.
Calculate heart rate training zones using Dr. Stephen Seiler's 3-zone model based on ventilatory thresholds (VT1/VT2). Supports both %HRmax and Karvonen methods.
Monitor recovery status with sleep quality tracking, fatigue indicators, and readiness scores. Get science-based recovery recommendations between sessions.
Visualize your entire training plan on an interactive calendar. Plan mesocycles, manage training load progression, and schedule race events.
FIT-DB is built on peer-reviewed sports science research. Our training intensity distribution model follows the polarized training approach advocated by leading exercise physiologists.
The heart rate zone calculator implements Dr. Stephen Seiler's 3-zone intensity model based on ventilatory threshold markers, validated across endurance disciplines including swimming, cycling, and running.
FIT-DB (Fitness Database) is a personal triathlon training management tool designed for age-group triathletes and endurance athletes. The platform provides structured training plans, workout logging, and performance analytics in a single integrated system.
Our mission is to make science-based training accessible to every triathlete, whether you are preparing for your first sprint triathlon or training for an Ironman.
FIT-DB supports Sprint, Olympic, Half-Ironman (70.3), and full Ironman distance training plans with customizable weekly hours and training phases.
Compatible with Garmin Connect — FIT-DB integrates with the Garmin Connect platform to import activity data including heart rate, pace, cadence, and power metrics directly from your Garmin device.
