1 - Personal illumination: Seeing and being seen is your priority
When night is falling or it is already dark, it is very important to pay attention to your immediate environment (potholes, puddles, branches strewn across your path, etc.) so that you do not fall or continue your walking session with soaked feet.
Take a torchlight with you, worn either on your forehead or chest: the most important thing is to know how to use it and be sure that the batteries will not give up on you during your walking session!
To be seen: make sure you wear light-coloured clothing and reflective bands on your arms and legs. You can even stick reflective bands on your clothes - anything is possible for your safety!
