COROS Running Fitness provides a continuous fitness score updated after every run, functioning as a proprietary alternative to VO2max. It analyzes pace, heart rate, grade-adjusted performance, and environmental conditions to produce a number reflecting your current running capability. The system tracks marathon fitness separately from base running fitness, acknowledging that 5K fitness and marathon fitness require different physiological adaptations. It also provides predicted race times for distances from 5K through marathon based on your current fitness score and training specificity.
What Running Fitness Doesn't Do
Proprietary score — not directly comparable to VO2max or metrics from other platforms
Running-only — no cycling, swimming, or multi-sport fitness tracking
Predicted race times assume optimal conditions and pacing — no course or weather adjustments
No structured training plan to improve the score — monitoring without prescription
What AiTrainingPlan Adds
Tracks fitness across all sports and provides standardized metrics for cross-sport comparison
Race predictions account for course profile, expected weather, and your specific race preparation quality
Prescribes targeted workouts to improve specific fitness dimensions — speed, endurance, threshold
AI identifies fitness plateaus and introduces new training stimuli to breakthrough
