Insanity Workout opinions?

amz1111

I currently go to the gym about 3 times a week and run twice a week, only seeing average results. I was wondering if anyone could give me their opinion on the Insanity 60 day workout programme? It looks incredible, but im sceptical it could just be another passing fancy. My other worry is that i have the great north run in september, and if i did the insanity workouts im not sure if i could train for that at the same time.. but would i need to? I would start the programme (if i did it) in july and finish end of August. The great north run is the 16th september.

Plus it's summer soon.. should i really being doing exercise inside? It would probably mean cancelling my gym membership too... I'm really unsure what to do! Any one that is currently doing the programme or has completed it, I'd really appreciate your views. Thank you!
