Gareness 

A state of Great Awareness similar to the oneness experienced through contemplative meditation, however achieved during physical exercise.

eg, you can achieve Gareness through long bike rides
eg, a person can reach a state of Gareness when the physical is transcended while experiencing muscle burn
eg, Dude, you totally won that race because you were in Gareness.

Gameness 

It is a determination to master any situation and never back down out of fear. Something that you must be born with, it can't be taught.

Thanks to his gameness, he took control of the fight when it went to extra rounds.
