Berlin Marathon Race Report: Splits and Analyzation (Pt. 4)

I feel really great about my showing in my first marathon, but now it’s time to get down to the numbers. I’m not going to be doing any “coulda, shoulda, woulda.” My most basic goals were to do my best and finish the race, prove to myself that I can do it, and I did those things. I’ll be more critical next time around, when I actually do focus more on pace.

Let’s look at 5k splits first, then 10k splits.

5k Splits

0 – 5k: 32:32
5 – 10k: 33:05
10 – 15k: 34:10
15 – 20k: 32:54
20 – 25k: 35:22
25 – 30k: 36:00
30 – 35k: 34:40
35 – 40k: 35:24

10k Splits

0 – 10k: 1:05:37
10 – 20k: 1:07:40
20 – 30k: 1:11:22
30 – 40k: 1:10:04

Analysis

Amazing, that’s all I have to say. I have never recorded such fast 10ks before, not even in training. I would love to run an actual 10k at the pace I ran the first 10k of this race. Not bad.

And the 5ks… They are more “all over the place.” The best was the first by 22 seconds, but I’ve run 3 miles considerably faster, so I’m pretty sure I can do a better 5k any time. Definitely not bad for the first 5k of a marathon, though!

Then there was a 36-minute 5k in there too, the 25 – 30 kilometers. As I said earlier, things are rather fuzzy in my brain during that time, so I was was obviously having a hard time of it. I’m kind of surprised that my last 5k wasn’t faster than the second-to-last, but that must be because I walked longer to encourage Denise (F546) at around kilometer 37.5ish, that’s the only thing I can figure there.

That faster second-to-last 5k is also a bit surprising because I am pretty sure the stop at kilometer 32 during which Rob re-secured my bib felt really long. Apparently it either wasn’t too fast, or I picked up my pace enough to offset the time. Or a combination of the two.

I think seeing these splits and thinking about what might have caused them will be important for my next marathon (whenever that will be…). They should help me figure out where I need to prepare for physical or mental weakness. Looks like I really need to be prepared from 20 to 30. I wonder if that’s normal. At the beginning and end, the excitement carries you, but in the middle you slow a little. Any marathoners reading this, please feel free to weigh in!
