A co-worker observed that I seemed to be more nervous about this 100-mile race than any other recent race. He was right. I really didn’t know what to expect, even though if successful, this would be my 30th career 100-mile finish in five years. My reason for a case of the nerves was a sore right knee. This knee had been scoped in 2004 and the doctor warned me that I should give up running. At that time I was not yet an ultrarunner, and not even a recreational runner. I ignored the doctor’s warning and put 14,000 miles on that knee since the operation. However, after my 83-mile run in the Grand Canyon on Thanksgiving weekend, the knee has been a problem again. Was my running career nearly over? The knee had calmed down, but I just wasn’t sure.
