I think running a 2 mile distance, 6 days a week would be considered moderate. As for exercising 2 hours a day, every day...that would depend on what you're doing. If you're doing yard work or house cleaning I don't think that would fall into either moderate or hard. If you're doing yoga and walking in addition to the 2 miles of running, I would say moderate. If you're adding in strength training in addition to the 2 miles of running, then I would say hard.
Maybe you could give more details about what it is you're doing for those 2 hours daily exercise? Keep in mind, my response is only my opinion.
If you are persistent, you will reach your goal. If you are consistent, you will keep it.
