Frequently Asked Questions (FAQ)
How is running pace calculated?
Pace is calculated by dividing your total running duration by the total distance covered. It is usually expressed as minutes per kilometer (min/km) or minutes per mile (min/mi).
What are splits in running?
Splits represent the time taken to complete specific intervals of a run, typically every kilometer or mile, helping runners track consistent pacing.
What are heart rate training zones?
Heart rate zones are percentage ranges of your maximum heart rate (HRmax). Zone 1 (50–60%): recovery and warm-up. Zone 2 (60–70%): fat burning and endurance base. Zone 3 (70–80%): aerobic fitness. Zone 4 (80–90%): threshold and speed. Zone 5 (90–100%): maximum effort. HRmax is commonly estimated as 220 − age, though the Tanaka formula (208 − 0.7 × age) is more accurate.
What is VO2 max and why does it matter?
VO2 max measures the maximum volume of oxygen your body can use during intense exercise, expressed in ml/kg/min. It is the gold standard for cardiovascular fitness. Average values: sedentary men 35–45, active men 45–55, elite athletes 70+. For women, values are typically 10–15% lower. Higher VO2 max is strongly correlated with longevity and reduced disease risk.
How do I calculate my one-rep max (1RM)?
The Epley formula estimates 1RM as: weight × (1 + reps/30). For example, bench pressing 80 kg for 8 reps estimates a 1RM of 80 × (1 + 8/30) = 101.3 kg. The Brzycki formula (weight × 36/(37 − reps)) is slightly more conservative. These formulas are most accurate for 3–10 reps. Always warm up thoroughly before attempting a true 1RM test.
What is a good running pace for beginners?
A comfortable beginner pace is typically 6:00–7:30 min/km (9:30–12:00 min/mile) — fast enough to elevate heart rate but slow enough to maintain conversation. The "talk test" is a reliable gauge: you should be able to speak in short sentences. Focus on consistency (3–4 runs per week) and gradual volume increases (no more than 10% per week) rather than speed.
