I personally have never been farther than about 7.5 miles from earth's surface.
Apollo astronauts have traveled as far as lunar orbit, around the far side of the
moon, roughly 238,000 miles from earth. That's about 1/2% of the distance to
Mars when Mars and earth are as close together as they can ever be, and about
1/4% of the distance to the sun.
The moon
The moon is the farthest a man has traveled. Mars is planned for 2018.
Currently, the farthest a human has traveled into space is about 400,000 kilometers. That is the distance from the Earth to the Moon.
The U.S. astronauts who've traveled to the Moon.
Humans have orbited the moon. When they were around the "back", they were about 240,000 miles from the earth. That's the record so far.

That would have to be the Voyager Project. It left the Solar System some years ago and it's still going strong.
