That's fine - what I recommended if you're determined to use BOTH products.
Running is catabolic, yes, but as long as you stay under 30-40 minutes (you know that I think ~20 minutes is plenty long enough for a cardio session), and your nutrition throughout the day (especially post-training) is fine, then you should have no trouble bulking.
If you're bulking though, you may want to cut your cardio back to 3-4 days a week - every day is definitely NOT required, and you want at LEAST ONE day off ALL training a week to let your body recover!
You could do this, one serving of Assault pre-training and then only 2-3 grams of creatine immediately post-training.
