Basic black is the way to go for many evening events. Runners and walkers who exercise in the dark need to see and be seen. To reduce their risk of close encounters with cars, they need to wear brightly colored and reflective gear between dusk and dawn.
Safety is first.
You have to be aware that motorists are not usually aware of you. That's what Judi Wilham and her husband, Bill, tell the runners and walkers in their Training for Life mini-marathon preparation program in Indianapolis. But runners have lots of options, because there's a growing array of glowing athletic gear available. A piece or two will do the job, but it's possible to outfit yourself from head to toe in apparel and accessories that flash or glow, reflecting the beams from vehicle headlights and street lights. It doesn't cost a lot to increase your visibility.
