Running blood is quite different from organ meats such as heart, kidneys, brain, liver etc. The word 'Running' has been used here to differentiate blood - from spleen that some people thought was blood.
Blood is Forbidden. Organ meats of Halal animals are nowhere Forbidden, so they are absolutely Permissible.
During Jahilyah, the Arabs used to bleed a camel and drink the blood. Recently, I have watched on video the British soldiers enjoying the drinking of chicken blood. Abhorring!
Kindly remember that in the Qur'an, Halal food is mostly accompanied by TAYYAB (clean, decent, aesthetically sound).

6:145 Say, "I do not find in the revelation given to me, any food that is prohibited for one who wishes to eat, except: Carrion (dead meat), or running blood, or the flesh of swine – for it is a barrier to moral development. Or, anything (not just meat) that, in defiance to commands, has been dedicated to other than God.” If one is forced by dire need without being deliberate and without transgressing, your Sustainer is Forgiving, Merciful.
[2:173, 5:3. Rijs = Unclean = Disapproved = Contaminated = Foul = A barrier to moral development. Science still needs to learn how pork can be a barrier to morality. Fisq = Deviation = Abomination = In defiance of Divine Commands = Disobedience of God = Drifting away from reason]
6:146 For those who are Jewish, We had prohibited some edibles, such as animals with undivided hoof, the fat of the cow and the sheep, except what is attached to their backs or their intestines, or what is mixed-up in the bone. But that was only a temporary retribution for their disobedience (4:160). We are absolutely True to Our Word.
16:115 He only prohibits for you the dead animal, blood, swine-flesh and anything that has been dedicated to other than God. In a forced situation, provided one doesn't exceed the necessity, remember that God is Forgiving, Merciful. [2:173, 6:145]
2:173 He has forbidden you: dead meat (carrion), blood, swine-flesh, and anything (not just meat) that has been dedicated to other than God (be it a person, an idol or a tomb 5:3). But if one is forced by necessity, neither intending disobedience, nor exceeding, it will not be a violation that hurts his own ‘self’. Indeed, God is Forgiving, Merciful.
[6:121, 6:145. Ithm = A violation that drags down the ‘self’ = An act that hurts the human ‘self’ = Anything that makes it difficult to rise up = An impediment to activity = Any action that depletes individual or communal energy. Ghafarah = Helmet and armor. Forgiveness involves protection from the detrimental effects of faults]
5:3 Forbidden to you (for food) are:
Carrion, blood, the flesh of swine, anything (not just meat) that has been dedicated to any other than God (such as an idol, grave or saint), any animal that has been strangled to death, or beaten to death, or killed by fall, or gored to death, or eaten by a wild animal unless you are able to slaughter it while it is still alive, and (also forbidden is) what is slaughtered on idolatrous altars (devotional stones or blocks in shrines considered sacred). And (you are forbidden) from dividing one another’s portions through raffling, for these are deviations. This Day, I have perfected your ‘Deen’ (Law) for you, completed My favor upon you, and chosen for you AI-Islam (Submission to God) as the System of Life. This Day, the rejecters of the truth have lost all hope of (making bargains in) your System of Life. But, do not fear them, but fear Me. This Day, I have perfected your religious law for you, completed My favor upon you, and chosen for you Submission (Al-Islam) as the System of Life. If anyone is forced by dire necessity (to consume the forbidden), with no intention of transgression, (should remember that) God is Forgiving, Merciful.
[Mayitah = Carrion = Dead meat = An animal that dies of itself. Azlaam = Dividing eating portions by placing or shooting arrows = In other contexts Azlaam also includes the conjecture of foretelling the future = Raffle = Lottery = Divining arrows = Clairvoyance = Dividing things or time for one another through randomly picking up slips of paper. Deen = System of Life = The law. 2:173, 2:185, 2:219, 5:90]
