Thanks everyone for the support. I am really happy with the result. It was a little warmer than I had hoped, but I paced myself well (despite a hilly course), fueled well, pushed hard through some tough sections despite my headphones dying at mile 20/km 32. A great first marathon and despite thinking it would be my first and last, I think I'm going to try again. 5km splits were insanely consistent. (That's me, thumbs up, about 1 mile in!!)
