I try to run or play basketball at least once a week. Usually shoot for 2 or 3 times when it's hot and I just want to stay in the gym. Obviously any aerobic activity is going to help condition your cardiovascular system so that's a plus. If cycling can help you get that training in on days where your body is obviously too beat up to run then, yeah, it would help you a lot. On the other hand, you can't primarily cycle and expect your body to stay in condition for the sort of running that you're doing. Low impact sports do not develop things like bone density, tendon and ligament strength, etc.
