yes, but it is just a 30 min aerobic run on the day I don't eat, the following morning it is a small meal of oats and protein 2hrs before I get back to the weights and sbr.
You really don't have to though...the big benny comes from losing the weight. Matt does a great job citing and explaining this in Racing Weight.
If all other things remain constant and you drop weight running becomes much easier/faster.
