Boston Half Marathon - 9/16/2012
I signed up for this half marathon the afternoon before. I wanted to use it for part of my long run but also wanted to push myself. I thought my 1:39 Half Marathon PR was soft and I thought 1:37 was doable.
The night before, we took my father-in-law for dinner for his 70th birthday. I didn’t drink but I ate a big steak and didn’t get to bed until 12:30. I was up at 4:45 to prep for this race (started at 7 a.m.).
Did an easy 3 mile warmup prior. The weather was almost perfect. Clear, dry and temps in the lower 50’s. This along with a flat course sealed it for me. I was going to go for it. I’d have time before my marathon in November to recover fully from this race.
Initially, my goal was to do 7:20-7:25 pace. That would put me at 1:37 time.
Mile 1 – 7:08 152
Went out a bit too quick for my liking but my legs felt okay….body still had a bit of chill from the brisk air and my HR was okay.
Mile 2 – 7:12 161
I really had to decide whether I would slow down or just ride it out at a faster pace.
Mile 3 – 7:16 161
Mile 4 – 7:18 163
Admittedly, my mind started racing about my slowing pace and my HR that continued to go up slowly but surely. I started to envision 8+ minute miles later in the race.
Mile 5 – 7:15 165
Something happened here. I just decided to go for it and see how long I could hold it.
Mile 6 – 7:13 165
I quickly realized my HR had stabilized. I decided to push it and keep banking my time and see how my HR would respond later.
Mile 7 – 7:13 165
Mile 8 – 7:14 166
Mile 9 – 7:11 166
Mile 10- 7:11 167
Mile 11- 7:11 167
Mile 12 – 7:07 168
Admittedly in mile 12, I was pushing the pace just a touch. I was hanging with the #6 and #7 women in the race. Eventually, they were pushing the pace faster than I was ready to do. So, although I picked it up, they picked it up more.
Mile 13 – 7:01 171
I passed a couple people here who were definitely slowing. The women though had really picked it up and must have rolled off 6:30ish final mile.
Last 0.16 – 6:42 174
I finished strong but didn’t try to kill myself. I was happy with my race and felt no need to blast my body with an all out sprint.
Time – 1:34:28 (PR!)
Overall - 60/1198
Men - 51/474
40-44 Age Group - 7/78
ARE YOU KIDDING ME? Pretty pumped up. Makes me breaking 3:30 in Philly a much more plausible goal. (My marathon PR is 3:36).
I’m also really pleased with how consistent my pacing was. I’ve never a run such a consistent pace in my life. I also usually run courses that are much hillier. But this race was just churning out the miles. I was in the zone.
For the first time, I really relied on the HR and it worked. (easy Ned…..I’m married.

) I’ll look at my other marathons, but I’m guessing a 155-160 HR during my marathon will be sustainable and will net me my 8 minute miles.
