My Marathon by the numbers

I spent the days after the marathon basking in the glory of my finish but quickly I was back to work in the gym and on my training plans.  First order of business was spending some time looking over the data behind my marathon.  I looked over my Garmin data and the race splits.  Overall, I'm pretty pleased that I was able to consistently bring my pace down over the second half of the race.  I can honestly say I'm surprised I was going so slow miles 25 and 26.  Sure my legs were tired, but I thought I was moving faster than that!

My pace, mile by mile from my Garmin:
Mile 1: 11:27
Mile 2: 10:54
Mile 3: 10:46
Mile 4: 10:08
Mile 5: 10:51
Mile 6: 10:51
Mile 7: 11:03
Mile 8: 10:39
Mile 9: 10:33
Mile 10: 10:27
Mile 11: 10:28
Mile 12:  10:11
Mile 13: 10:20
Mile 14: 11:00
Mile 15: 10:25
Mile 16: 10:24
Mile 17: 10:25
Mile 18: 10:14
Mile 19: 9:58
Mile 20: 10:23
Mile 21: 9:46 (Oops, too fast!)
Mile 22: 10:15
Mile 23: 10:18
Mile 24: 10:07
Mile 25: 10:32
Mile 26: 10:36
Mile 26.2: 9:36
Finish: 4:38.42

Overall: 11568 / 23714 (Top 48%)
Gender: 3878 / 9985 (Top 38%)
Division: 796 / 1854 (Top 42%)

Key observations:
- Mile 4 was too fast.  I think we had just finished a bunch of hills and were ready to start moving a bit faster.
- Mile 21 was too fast.  I was getting a little too excited about the finish line ahead of me!
- I still had some kick into the finish line - that was fun!
- The first half marathon of this race, 2:22.45, was faster than my first two half marathons.
- The second half marathon of this race, 2:15.53, was faster than my half marathon PR at last year's Wine and Dine half.  Wow!  I've gotten a lot faster this year.
- Average pace for first 13 miles: 10:39.  Average pace for second 13 miles: 10:17. Whoa!  That was a bigger change than I expected!

Do you spend time analyzing race data?


  1. I should probably claim responsibility for that mile 21 speed, I think that's when I started to pick it up - sorry!

    I'm glad you posted this, since I had my Garmin set for the intervals I only get the data by intervals so I'm not able to see it broken down by mile, I meant to ask you if you could send me this!

    I still can't believe we both negative split by so much - go us! : )

    1. Haha that's ok - I might not have finished under 4:40 otherwise! :) I noticed that in the begining we would have 2-3 consistent miles, a fast one and then a slow one haha! A coworker of mine actually did the math for first half and second half average pace...he announced it on a very large teleconference. I was both proud and mortified haha!

  2. Nice analysis and great job on the race! Congratulations!!!

    1. Thanks April! I'm an engineer by degree so nerdy analysis is my thing!

  3. Great splits! Way to stay strong the entire way. Did you run the entire way or do run/walk intervals? I'm trying 2:1 intervals as I get into longer runs but I think I'm going too slow when I walk and it's keeping my pace slower. Or maybe I need to do my running faster? Any advice for this?

  4. That's amazing! Congrats! I'm training for my first marathon at WDW this January. If you could choose a few key workouts from your training that helped you get these splits what would they be? I appreciate the advice!

  5. Regardless of your pace, splits, etc, you did GREAT! Congrats! But I know what you mean, it is always fun to go back and analyze your accomplishments. It in some ways confirms "yea, I rocked that race"

  6. Awesome job -- totally inspiring as I head into my first marathon in two weeks!

  7. Way to go!!! That is so epic to me. I am just happy I am finishing 10ks at your marathon pace. You rock!!

  8. Great job Christine!! You definitely kicked some booty!

    I love analyzing race data. I blame it on my type A personality haha!
