  • 10 Percent Rule

    Injury from volume spike — never exceed 10% weekly increase.

  • Taper Trust

    Taper feels wrong but works — do not cram miles last week.

  • Warning

    Know when to DNF — persistent pain or confusion means stop at the next aid station.

Safety Notes

  • Overtraining — monitor resting heart rate.
  • Trail roots — ankle strengthening pre-training.
