so you're a young white male - black men running are more likely to need to prove they are't running to or away, but for fun. Gear signals "runner" vs "arrest me". Ymmv on this one these days but the black guys running in my area were always careful to look the part.

in a safe location Fairly obvious. Phones at a minimum. Pepper spray too sometimes. Safe varies by gender. I ran through a heavily monitored area (data centers and government offices at 5 am) near a police station and still had a car turn and slow to follow me for a bit until I found a lit shopping are with people.

Running short distances Longer distances need water, electrolytes, and a phone. A bit of moleskin for blisters and a pack of tissues is also useful. If you're regularly doing 2-3 hours running without water, I would maybe worry about your kidneys.

in good weather A little rain isn't bad weather. If you are half naked running in the snow, I am going to assume you are on drugs. "Good weather" is also relative to running. If you are running in high humidity or heat, you need a hat, a shirt or sunblock, water, electrolytes.

During daylight hours only

You know folks running in the dark without a headlamp or reflective vest?
