I wonder, was (/is) there any very very strong man of great virtue? (the person need not be an athlete, he could've just as well been a lumberjack or blacksmith etc. Also, any great bodybuilder also qualifies)
Virtue as in, say, Charity, Kindness, Patience, Self-Control/Temperance, Humility (at least not being incredibly proud) and Chastity (as in "one wife" not partying with the ladies until dawn). Maybe not an avatar, but at least more than the average human.
Edit: must have been famous. There certainly were lumberjacks, blacksmiths and even a few knights.
