Does running help rid THC

Possibly; THC is fat-soluble, so burning fat can increase the rate at which the body eliminates the detectable compounds. (Despite a common misconception, burning fat that contains these compounds doesn't make the exerciser "high a second time around.")

However, this is greatly influenced by a lot of factors. Some people can smoke marijuana on a daily basis for many months, exercise and drink lots of water for 2 or 3 days, and then pass a urinalysis drug test. Others will fail the test several weeks after cessation, regardless of exercise. Many "detox" products advertised online only hope to dilute your urine; modern urinalysis drug tests can detect highly diluted urine.

So, the tried-and-true method for eliminating marijuana compounds from your body is to simply wait it out with time, exercise frequently, and drink lots of water. On that note, exercising frequently and drinking plenty of water isn't bad advice, regardless of drug use.
