Another sub-three by the skin of my teeth. 2:59:35 gun time, maybe 30 sec better on chip time (yes, I was up pretty close to the front). Strategic mistake was to start needing a pee. By 15k there was no choice but to stop. That was 50 sec. Went through half in 90 min 30 sec. So for the first time I had to negative split and somehow pulled it off. It was amazing. There was a grey haired old man sitting on my shoulder urging me on. More later. Off to celebrate now!!
