This is most discouraging -- Micah True, awesome and unbelievable ultramarathoner, who probably logged 100 miles or more every week and lived on a super-healthy diet, including lots of chia seeds, evidently dropped dead during a routine 12 mile run in New Mexico. He was 58, not much older than I. He was one of the heros of Born to Run, one of the few books about endurance sports actually worth reading (actually, there are quite a few, but small as a percentage of the total -- other good ones include Lance Armstrong's It's Not About the Bike and Lynne Cox's Swimming to Antarctica). So here is a guy who runs (ran) like a fiend, eats (ate) only what he should, and pretty much devoted his life to doing good and boom, he drops dead. Seem rather unfair or something. I hope it turns out that he had an undiagnosed aneurysm or something and didn't just give himself a heart attack by running too much. There is some recent evidence that extreme endurance sports can damage your heart, however.
