Not medical advice
No content on 26m.com — including run scores, clothing recommendations, training plans, heart rate zones, VO2 max estimates, BMI calculations, or any other output — constitutes medical advice. Always consult a qualified physician before beginning or changing an exercise program, particularly if you have cardiovascular, musculoskeletal, or other health conditions.
Weather accuracy
Weather data is sourced from Open-Meteo and reflects forecast or current conditions at your requested location. Forecasts are inherently uncertain. Conditions can change rapidly. Do not rely on this data for safety-critical decisions. If conditions look dangerous, trust your instincts over an algorithm.
Training plans
Training plans generated on this site are algorithmic guides based on your stated goal time and current mileage. They are not personalised coaching. They do not account for your injury history, sleep, nutrition, stress, or any other individual factor. A certified running coach can provide guidance that no algorithm can.
Ultra-marathon distances (50K and beyond) carry serious physiological risks including but not limited to: hyponatremia, rhabdomyolysis, hypothermia, hyperthermia, and severe musculoskeletal injury. Appropriate prior experience, medical clearance, and a trained support crew are essential before attempting these distances.
Pace and performance estimates
VDOT scores, VO2 max estimates, equivalent race time predictions, and pace adjustments are derived from published exercise science models. They are estimates. Individual physiology varies significantly. These numbers are starting points for planning — not predictions of what you will run.
