Character run cycle

I have finally started to animate my character using the walk cycle, he moves well and all his features work perfectly. Running cycle is one of my weaknesses which I struggle work with mainly for the reason of my characters always jumping steps or in other words jittering which refers to the missing points of action in an animation resulting incomplete and jumpy movement.

So far I have coped with the key-framing and am finding it fun to do so, my movements for my character are very simple because his run cycle is just one cycle in one place repeating itself because my character does not move any where else apart from being on a treadmill so my animated role is simple. I have enjoyed working on running cycles have been easy so far because maya functions simply with key-framing, I originally thought the process of key-framing was going to be hard based on Maya being a complex package. Referencing has been very useful and I have understood thoroughly how to animate a run cycle stage for stage.  

To make sure my character moves properly for the animation I will need to focus on the stages of the movements to make sure my characters move right and in the correct and precise angle or points. my main points I will need to focus on based on my use of Maya would have to be steps of my run cycles because I never seem to get the stages of a walks cycle right, will need to keep to reference guide in order to get my run cycle right.
