  "summary": "Calculate stride length from distance and step count using biomechanical gait-cycle definitions.",
  "description": "This calculator computes stride length—the distance covered in one complete gait cycle (from one foot contact to the next contact of the same foot)—using the biomechanical definition that one stride equals two steps. It divides the distance traveled by the number of steps recorded, then multiplies by two to convert step length into stride length, reporting both metrics in centimeters and meters. The method follows the gait-cycle definition established in biomechanics literature and is applicable to walking, jogging, and running activities where step count and distance are known.",

  "faqs": [
    {
      "question": "What is the difference between stride length and step length?",
      "answer": "Step length is the distance from one foot contact to the next opposite-foot contact. Stride length is one complete gait cycle—left foot contact to the next left foot contact—which equals two steps. This calculator computes both, with stride length as the primary result."
    },
    {
      "question": "Why does my running watch show a different cadence?",
      "answer": "Most watches report cadence in steps per minute (individual foot contacts), not strides per minute. A cadence of 180 steps per minute equals 90 strides per minute. This calculator uses steps (foot contacts) as the input and multiplies by two to derive stride length."
    },
    {
      "question": "How can I measure my step count accurately?",
      "answer": "For the most precise count, run a known distance on a track (400 meters is standard) and manually count each foot contact, or use a running watch with a footpod or accelerometer. Video recording can also help verify step count over shorter distances."
    },
    {
      "question": "Does stride length vary with running speed?",
      "answer": "Yes. Stride length typically increases with faster paces and decreases at slower speeds or uphill. Elite runners exhibit longer strides at race pace than during recovery jogs. This tool calculates average stride length over the measured distance; it does not capture within-run variability."
    },
    {
      "question": "What stride length is optimal for distance running?",
      "answer": "No single stride length is universally optimal. Efficient stride depends on leg length, strength, flexibility, and individual biomechanics. Research suggests a cadence near 180 steps per minute (90 strides per minute) is common among competitive distance runners, but individual variation is large."
