Doesn't count time from when Garmin said 20 to end, but somehow official results have me a few seconds faster. Didn't get in the wave with the 3:30 group and never caught them. At 4 miles realized no way I was going to maintain 8min/miles but by then too late to avoid a rough finish. Splits also reflect tailwind until mile 13 and then headwind the rest of the way. Still, happy with first twenty in 3 years.
