If you choose to run during winter: 

• Avoid high-snow areas or routes with parallel streets, as it can expose you to sudden cold. 
• Avoid areas with street puddles, and do not run near the transit route of buses, which can splash you with cold water suddenly.

• Try to run when there is sufficient daylight. This helps avoid any tripping or falling.

• If it is snowing, avoid large puddles and slippery surfaces.
