Jim's typical VO2max was 5.9 liters (which of course is 5900ml) and if you divide that by his body mass that varied a bit (usually around 73kg), you get 80.8. I did get a 6.0 liter max one time, and that gives an 82.2 per kg value (identical to what I usually got for G L). The highest I personally ever tested was Ron Clarke, at 6.4 liters (use whatever weight you have confidence in to get a per kg value). In those days lactate evaluations were not available in the field and we did not do any. Can't comment on #3 -- ganske pa Svenske nagontid (sorry don't have all the Swedish letters on my keyboard)
Drew -- one of my favorite Alamosa stories was the time Jim and I had breakfast at a pancake house and as we got up to pay a teenage girl (who ate near us with her younger brother) said to Jim, "My brother thinks you look like Jim Ryun," to which Jim replied, "Yes, I am," to which the girl replied, "No you're not," and after one more round of the same we just had to let it go at the fact that he was not Jim Ryun. And Jim went back to his $1.50 per hour job at a local grocery store, to pay for his time training at altitude (an even better story one day at that store).
I better start writing all this stuff down before it gets lost.
