I went out tonight and ran 9km. Had a good run.
Whenever I go out at night for a run, I make sure to wear a white, or light, shirt. I realize, as a driver, that dark shirts can be difficult to see at night, and it is dangerous. I see a lot of runners and walkers wearing dark clothing - shirts, skirts, long pants, and it is really dangerous. While walking/running on the sidewalk, it is no big deal. But if you are running in the street or even when you go into the street to cross the street or if the sidewalk is damaged so you need to step into the street for a bit - it is really dangerous and drivers can have a really difficult time seeing you.
Please - runners, walkers, etc. - please, at night wear light shirts, if possible with reflectors of some sort to improve your chances of being seen by drivers.
