For a 39°F (4°C) run, wear a moisture-wicking long-sleeve base layer, running tights, light gloves, and an ear-warmer or beanie. Add a wind or insulated layer if it's breezy. Dress to feel slightly cool at the start.
No, 39°F (4°C) is not too cold to run outside. With proper layering it's very runnable — focus on covering your hands, ears, and head and wearing moisture-wicking fabrics.
Most runners wear tights at 39°F (4°C). Your legs generate a lot of heat, but full-length tights keep you comfortable at this temperature.
