Last year I finished Boston in 3:42. It was my second marathon and I wrote all about it here.

Since then I have been training hard, following a rough Hal Higdon plan roughly and putting in my 20-40 miles a week. My PR for a half marathon is 1:39 and the calculators seemed to think I can do a 3:27. I also used the Yasso estimator and could repeatably hit 3:30 800 yard repeat sprints. OK, put it all together and I was going to go after a conservative 3:38 this year, something like an 8:20 pace.
We got to Runner's Village and I waited in the 35 min bathroom line, later found some sunscreen, and overall was ready to go. I felt good, weather was nice - still a little chilly to stand around in short sleeves but warming. Once they called our group off we went.
Miles 1-2 - Very congested, seemed to be moreso than last year. I planned on 8:30s through here ('warming up') but couldn't really maintain that pace with the others blocking the way. As a result I did what I said I wouldn't and was playing dodge-the-guy in front of you. There is an uphill at 1.5 and people were slowing to a 10 min pace...had to really make moves to get around them. I came out of the 2 miles at 8:33 pace - almost perfect. Then I realized my heartrate was at mid-high 150s, the upper end of my aerobic zone. Slight concern, but figured once I settled in I would be fine.
Miles 2-9 I planned to get into a groove at 8:20. I see now that I was closer to 8:10/8:15 through here. I was sweating a decent bit as well, something that I wasn't planning on this early. The sun was blasting and we didn't get shade all day. The runners had thinned enough that I wasn't dodging as much, but by this point I was watching my heartrate closely. You can see from the splits that I slowed a couple times closer to 8:30 to try and get the heartrate down but it wasn't budging. Still, I figured if I can keep it in the 150s I should be ok. Still feeling strong, miles were coming along easily.
I should mention the crowds, they were fantastic. I was pretty animated, slapping plenty of hands and shouting to the crowd, having fun. Great signs throughout (my favorite was "I do my marathons on Netflix") bands, just very positive.
So at Mile 9 I am averaging 8:20 and feeling fine, but worried about the high heartrate. Logically I knew I should slow, but competitively I had to keep pushing, couldn't give back that time I had built up to this point. Miles 9-16 I planned to pick it up to 8:10 pace. I picked it up for a couple miles and watched the heartrate climb into the low 160s, which I knew meant leaving aerobic zone. Soon I slowed back down to 8:20/8:30 pace but the heartrate wouldn't stop climbing. At this point I knew I was in trouble and that it was only a matter of time. Fatigue began setting in, which didn't worry me much, but I knew cramps were nearby. My wife/family/friends were at Mile 14.5 so I just focused on that. At this point I was still on a 8:17 pace.
Seeing my family and friends was awesome... I stopped for a couple minutes for photos, hugs. I wanted to warn them that disaster was near for me but before I knew it I was back in the crowd bounding off.
Mile 15 or so is when the quad started twitching, and at Mile 16.5 (beginning of the Newton Hills) shows the first cramp where I had to stop. I massaged it and kept moving, but a mile later it was back in force. At Mile 19 I ducked into the Medical Tent and a nice woman gave me a massage. It felt better, but within a mile I was right back where I started, cramping hard. I was run/walking from this point forward. I tried another Medical Tent at 21, but they were busy with others... I used the time to take a breath and then headed back out.
The crowds at BC were awesome and in Brookline to the finish. They were cheering hard to get me to run if I was walking and I did my best - honestly they carried me through. Those last 5 miles I managed a handful of 9:00 pace quarter-mile splits, run til the muscles locked, then walk til they loosened a bit and repeat. I caught up with a few team-members and as we turned onto Boylston we ran straight down to the finish, crossing with our arms raised. Finished at 4:10, 28 mins slower than last year and with severe positive split.
So that's that, toughest run I have ever done and in stark contrast to last year's run. I am still not sure what changed so drastically this year...weather was warmer but not excessive, pace was a little quicker but not excessive. I was sick last week but seemed ok. Maybe it was a combo of all of these things.
Lesson learned - heartrate doesn't lie. I plan to start running more to it than pace going forward, not looking forward to putting myself in that spot again. Still it was a helluva day and I was glad to be a part of it.

I only put up first 14 as my pace went all over the place afterward
