Well, there is no real way to actually run on ROBLOX, but if you have a run tool in possession, just select it, hold down the left mouse button, and walk like normal. It will make you walk faster than normal. Also, some morphs and suits you can get as models make your walk speed faster (examples - a Sonic the Hedgehog morph, a Robot suit). Also, some gears you can find in games have secret ways to activate a run feature (such as in the game, Gravity Gun Fun, if you push the key "F" when you have the Gravity Gunselected, your speed doubles).
It is better to walk then run in the rain.
