117th running of the Boston Marthon. I started fast, hitting the 5K mark at 18:36 and holding strong through the halfway point in 1:23:08. A couple of side stitches, first on the left, then right, brought me back down to Earth and reminded me that my primary goal was breaking three hours. I cruised at about 7:00/mile until Mile 18, where we hit the Newton hills, the most notorious of which is Heartbreak Hill, which crests at the Mile 21 Marker. The wind really kicked up as we turned onto Commonwealth toward Boston, and I wisely held back on the downhills because I could feel hamstring cramps creeping in. I fought hard the last few miles, finally kicking at the Mile 26 Marker to finish in 2:59:11.
