I havent read the whole thread but I don't think the 50/50/50 is impossible by any stretch. This past thursday and friday I did the following:
Thursday 4 PM - 14 Miles
Thursday 11 PM - 7 Miles
Friday 12 AM - 1 Beer
Friday 7 AM - 9 Miles
Friday 3 PM - 12 Miles
Friday before midnight - 12 Beers
So in 32 hours I already had 42/50 miles complete, and 13/50 beers complete. I was just going about my normal business and had not even heard of the 50/50/50 at the time. There was a lot of room to squeeze some more in there too. I went to class on friday, easily could have put down 3 beers and taken a nap instead prior to my afternoon run. Also could have added 2 beers before bed on friday night. This would have given me 18 beers in the first 32 hours. So from there lets say I sleep for 8 hours, get up and put in my last 8 miles, leaving me with 9 hours to drink 32 beers. Obviously going to be difficult, but by no means impossible. If you break those 9 hours out with the following beers per hour, 2 , 2, 2, 3, 3, 4, 4, 4, 8, I think it is definitely POSSIBLE. Although, I have no interest in doing it any time soon.
