Choose visibility
In poor light, start with a familiar, lit route and use reflective clothing. A light can help you spot uneven surfaces. Make sure you are visible from the direction of traffic at crossings.
Judge the surface in person
Conditions can vary between a sheltered block and an exposed path. Slow down or walk where grip is poor, and turn back if the next stretch looks worse. A short walk or an indoor session is a practical alternative.
Make the return easy
Plan a turnaround near a warm indoor space or transport stop if the weather changes. Bring a dry layer if you will be standing around afterwards. Check the conditions again before heading back out.
