For my run cycle I started off with a reference from the Animators Survival Kit.
I used this image to build up my basic key poses. From here I tweaked the feet outwards and rotated the hips and the top of the chest. I decided to use this rig since it was really maneuverable. I also used the main rig around the waist to adjust the height of the jump between steps. I also added in some curvature to the feet, bending them slightly when the foot was landing and lifting off.
Once I was happy with the final outcome, I added in a single directional light and a camera to set up my scene. I also used the show tab to remove the hud display as well as the controls around the rig.
For rendering I used Arnold within Maya. I changed the format to PNG and changed the display to 1020. From here I used this image sequence and imported them into Premier Pro to combine and connect to make my animation loop. I exported the video as a H.264.
Below is my final animation:
