The Devil Dogs are one of my favorite bands.
Lindgren indeed has mental stability issues and to expect the kind of consistency and rationalism from his as you do other people is unrealistic. It is not like he is all of a sudden going to get better. People making fun of him of being critical of some of his statements should really take a long look in the mirror and be thankful that they have not had to live with the demons the Lindgren has.
But he is also a guy that beat the USSR runners in the 10,000 meter race in a dual meet in 1964 as an 18 year old. This was a truly astonishing accomplishment. Then just a year later was placed in a ridiculously untenable situation for anyone, let alone an 18 year old kid, during the NCAA-AAU quest for control. The pressures he received from both sides was also astonishing. Then of course he disappeared for all those years.
I wish him well, happiness, and hopefully some contentment, for the remainder of this life. I don't really care whether he did a 147 mile run or not, or whether he thinks he did and did not, or whatever. It just does not matter right now.
At least half the people that post in Lets run lie about their best mile or 10K times anyway.
