Keep the Drunk Guy Walking

42 Meters.

Given all the pratice I've had, you'd think this would easier.

Edit: Just got to 74.
 
Im not a good drunk walker I guess - I only got up to 31
before I quit
 
I did 133 and gave up. There's a trick to keep him walking straight. I don't want to spoil the game for you guys, so I won't say.
 
52 and I don't drink!!!
