You definitely want both your rear light and front light if your going to be riding that early and on a bike path like that. For the most part its a pretty good ride, but im pretty sure that the bike path goes out into the westlock area, like by the central traffic zone. So your going to want to watch for that, definitely advisable that you are visible. Most of it is pretty good in terms of pavement, but some parts can be pretty crappy. maybe a few pot holes or gravely spots hear or there.
I haven't really ridden it in a while so it would be nice to start riding it again. Its a nice stretch, there can be quite a bit of bike traffic at certain times of the day, so its not dangerous to ride really. Well I hope you have a good time riding and welcome to the forums. Hope to see you out there sometime!
