What this site is
26m.com provides free tools for runners — including a weather-based run score, clothing recommendations, and running calculators. All tools are provided as-is, for informational and entertainment purposes. Nothing here constitutes medical, fitness, or safety advice.
Use at your own risk
Running outdoors carries inherent risk. Weather data may be inaccurate, delayed, or unavailable. Clothing recommendations are general guides. Scores and verdicts reflect algorithmic outputs — not professional assessments of your specific situation, fitness, or health. Always use your own judgment before going outside.
Ultra-marathon training plans, in particular, carry serious physiological risk. Consult a physician and experienced coach before undertaking distances of 50K and beyond.
