Nothing should get in the way of a training run, so for me, lighting is important. Getting run over might slow me down.
When choosing how to illuminate yourself, crank the screen on your smartphone up to 100%, stare into it, and think about what you are competing with.
When running on the highway, I make sure to 'spear' oncoming drivers with my headlamp, a few times. This ensures that they see me in plenty of time to plan.
When I hear traffic behind me, I spear the signs ahead, as this reflects and again, attracts the attention of the drivers.
When approaching an intersection, I shine my beam around it as I approach, again to be more conspicuous.
My light dims itself when pointing at something lighted, so it's easier on the drivers than it might be otherwise. My chosen headlamp at the moment is the Petzl Reactik. Rechargeable, great quick adjusting strap and has an app so you can play with the features on your phone if you want.
I use a headlamp, with a blinker on the rear, blinkers on my mitts, reflective outerwear highlights and a noxgear Tracer360.
Where I run, I am often sharing open lakes with skidoos capable of terrifying speeds, and so I am a bit pro-active about being seen.
I should say that I get free gear from Noxgear for promoting their stuff. They send me a free one when a number of people in my hometown strava group uses our discount code. I won't give you the code here, because I don't really care about what you light up with, just try to make it better than this. :)
Wearing it I feel like the love child of James Cagney and Andy Gibb.
doesn't it have a manly-disco vibe?
