When I go out running I (always) carry this:
iPhone 4S, with the following apps running; Spotify and Runkeeper (missing in photo due to camera in use)
Headphones (CHEAP from Thailand, but they’re the only ones I’ve found that stay in my ear while running)
New Balance Armband
Hot Pink Mace
Garmin Forerunner 405CX
Sunglasses (if sunny)
Q: What are you bringing on your runs? Something you just can’t be without?
