Understanding and balancing training stress for optimal performance
Successful endurance training is about finding the right balance between stress and recovery. Stride helps you manage this balance through three key metrics: Load (fitness), Fatigue (tiredness), and Form (readiness).
Load represents your current fitness level. Think of it as your “fitness bank account” - the cumulative training you’ve done over the past 42 days.
The golden rule: Don’t increase Load by more than 5-7 points per week to avoid injury and burnout.
Athlete Level | Typical Load Range | Weekly Hours | Description |
---|---|---|---|
Beginner | 20-40 | 3-5 | New to structured training |
Recreational | 40-60 | 5-8 | Training for fitness/fun |
Enthusiast | 60-80 | 8-12 | Regular events/races |
Competitive | 80-100 | 12-15 | Racing seriously |
Elite Amateur | 100-120 | 15-20 | Podium contender |
Professional | 120+ | 20+ | Full-time athlete |
Fatigue shows how tired you are from recent training - calculated as your 7-day average Training Score.
Form = Load - Fatigue. It indicates how ready you are to perform.
-10 to -25 Form: Optimal for building fitness
-10 to -25 Form: Optimal for building fitness
-10 to +5 Form: Balanced and ready
+5 to +15 Form: Race ready
Build Week (Increasing Load)
Recovery Week (Absorbing Training)
High Load, High Fatigue, Negative Form
Situation: Load 85, Fatigue 95, Form -10
Meaning: You’re fit and training hard. This is sustainable for building fitness.
Action: Continue if feeling good, consider easy day if very tired.
High Load, Low Fatigue, Positive Form
Situation: Load 85, Fatigue 75, Form +10
Meaning: You’re fit and fresh. Ready for peak performance.
Action: Great time for racing or testing. Don’t stay here too long.
Low Load, High Fatigue, Very Negative Form
Situation: Load 45, Fatigue 65, Form -20
Meaning: You’re doing too much too soon.
Action: Reduce training intensity. Focus on consistency over big days.
Declining Load, Low Fatigue
Situation: Load dropping from 80 to 70, Fatigue 50
Meaning: You’re losing fitness from insufficient training.
Action: Gradually increase training volume to rebuild.
Base Phase (12 weeks)
Build Phase (8 weeks)
Peak Phase (3 weeks)
Form Range | Training Decision |
---|---|
Below -30 | Take rest day, risk of overtraining |
-30 to -20 | Normal hard training, monitor fatigue |
-20 to -10 | Balanced training, ideal for most days |
-10 to 0 | Fresh, good for intervals or testing |
0 to +10 | Peak form, race or maintain |
Above +10 | Too fresh, losing fitness, train more |

Remember: Fitness is built during recovery, not just during training. Respect the recovery process!
