64–77º. I made my sub-four-hour goal! But it wasn't easy. I reached the seventh mile with an extra minute to work with, thanks to some uneven, excited pacing. I was steady to mile 20, but the course became much warmer and quieter as I entered uncharted distance territory. My pace slowed, and I lost my buffer minute by mile 24: six seconds behind schedule. I felt awful, but increased to an 8:46 pace to finish the race. I was too tired and walking funny to be jubilant at the finish line, but I'm very happy I made it. It was also amazing to see my wife four times along the sidelines; with 45,000 runners, I didn't expect to see anyone. Thanks to everyone on DM who motivated me throughout training!
