I ran a sub-90 minute half marathon at Rock ‘N Roll D.C.

After three failed attempts last fall, I finally did it. I broke 90 minutes in the half marathon at the St. Jude Rock ‘N Roll D.C. Half Marathon on St. Patrick’s Day weekend! My official time was 1:29:27, good enough to win my age group and finish among the top 50 females at the race. 

I’m honestly still on cloud 9. Yes, Boston has been the focus of my training, but the desire to run a sub-90 half never went away and when I registered for Rock ‘N Roll D.C. a month out from Boston, I definitely thought “maybe this is my shot.” And it was! 

Here is my recap of my first sub-90 half marathon! 

I was originally registered to run the Cherry Blossom 10 Miler – I had gotten in as a seeded runner, meaning I was able to bypass the lottery because of my time at Cherry Blossom 2022 (still my 10 mile PR.) But when I registered, I did not realize it was 8 days before Boston and I knew I did not have the discipline to not race it all out …. So I transferred my bib to an Instagram friend’s husband. That’s when I decided to register for Rock ‘N Roll D.C. on March 16. I had run this race before, wayyyy back in 2015, as I trained for the Pittsburgh Marathon. I ran a then PR of 1:46 on a day with torrential downpours. I really enjoyed the course, even though the weather blew. I knew there were some rolling hills, but nothing crazy (or so I remembered!) I also ran the marathon, which no longer exists, in 2016. So I decided to register for the 2024 race. 

I wasn’t expecting there to be any pacers, as I couldn’t find anything on the website that said anything about pace teams. But I was pleasantly surprised to find out there was a 1:30 pacer, whom I met at the expo the day before the race. He told me he planned to go out slightly ahead of pace due to the infamous hill in Rock Creek Park. I did remember that hill from when I ran the half marathon and marathon years ago, but didn’t think it was going to be all that bad. (Spoiler alert: It was.)

On race day, I got up extremely early and got to D.C. by 6 am, even though the race wasn’t starting until 8. Ridiculously early, yes, but I was still scarred from my experience getting to the Annapolis Running Festival so damn late. At least I wasn’t rushed!! I checked my bag, used the porta potties about 100 times, LOL, chatted with other runners, and did a 1-mile warmup before hopping into my corral around 7:45. The weather was perfect. Low 50s, very little wind. The cherry blossoms were also blooming and looked beautiful! It was sunny enough that I didn’t wear arm warmers with my tank top and shorts, and felt very comfortable as soon as I started running. 

Rock ‘N Roll D.C. is a big race – over 13,000 people in the half, I think. (There is also a 5K.) I was put in corral A, just behind the elites, and the course was initially very crowded and I felt boxed in at the beginning. My goal pace was 6:50, but I ran the first mile around the National Mall in 7:07, which did not inspire much confidence for the rest of the race. Still, I told myself it was only the first mile. Lots of time to make up the difference.  

Mile 2 was a 6:52 – OK, much better, and I was locked in with the pace group by then. There were probably about 15 to 20 of us running with the pacer, and we were almost elbow to elbow as we ran across Arlington Memorial Bridge and back.

Those miles flew by, and I ran a 6:39 for mile 3 and a 6:18 (maybe?! The buildings could have messed up my Garmin) for mile 4. At that point, I was like, shit. 6:18 is faster than my 5K PR pace, so the fact that I ran that fast so early in a half marathon – if it was indeed accurate – was a bit alarming. But I was feeling pretty good and was able to get down a Maurten gel, and I continued to hang with the pace group. At that point, we were running down Rock Creek Parkway, and I knew the Rock Creek hill would be a little more than halfway through the race. The next few miles were also ahead of pace, but they were pretty flat: 

Mile 5: 6:43 

Mile 6: 6:36

Mile 7: 6:44

The hill came around mile 7.5. And. It was SO MUCH WORSE than I remembered. Heartbreak Hill ain’t got nothing on this incline. The Naval Academy Bridge is a piece of cake in comparison. This hill crushed my soul and I thought my race was over when I got to the top of it and the pacer left me (and a bunch of others) in the dust. I almost wanted to walk for a second, but there were so many spectators lining the course there, including a sergeant yelling “come on! It’s only a speed bump! Get to the top!” Haha. When my watch beeped for mile 8, I saw I had run a 7:06, so I definitely slowed down significantly, but not as much as I’d feared. But still, getting back up to speed wasn’t easy and I had lost track of the pacer, which was discouraging. I told myself to just do the best I could. 

I had been told that the race course was mostly flat and downhill after you turn onto Calvert Street following the Rock Creek hill, but honestly, that’s BS. There are a lot of rollers in the later part of the race. But I was able to drop my pace to sub-7s again. The race was definitely getting harder and the sun was glaring in my eyes despite my sunglasses, but I wasn’t going down without a fight. 

Mile 9: 6:58

Mile 10: 6:41

I hadn’t set my Garmin to elapsed time, and I actually had no idea how much longer I had to break 90. And I can’t really do math under the best of circumstances, so forget about trying to do it in a half marathon. I just tried to run as fast as I could, and I threw down some surprisingly fast miles in the final 5K of the race. There were more spectators around at that point as we headed toward the Capitol, but to be honest, I was so in the zone that I can’t remember much.

Mile 11: 6:37

Mile 12: 6:26

Just after I hit mile 12, I saw the pacer right up ahead of me! I had caught up! I thought he was probably aiming to finish just under 1:30 and I told myself, just hang on. You’re almost there. You might really be going sub-90! The main thing I remember is that around mile 12.5, the last band on the course (as it’s a Rock ‘N Roll race, there are bands every mile or two) was playing a rendition of the ‘90s R&B slow jam by Mint Condition, Pretty Brown Eyes. Love me some ‘90s R&B, but that was an interesting choice late in a half marathon. 

I ran mile 13 in 6:53, made the final turn toward the finish line, and gunned it as best I could. I’ve  never been great at that final kick, but I ran the final 0.29 (guess who was crap at running the tangents? I was probably weaving around other runners too much in the earlier part of the race) in 1:44. I immediately stopped my watch and saw 1:29:29 (official time was 1:29:27), let out a scream, and went up to the pacer and hugged him. My pace according to my Garmin was 6:44/mile over 13.29 miles. Again, I did not excel at running the tangents in this crowded race. Maybe if I’d run an actual 13.1, I could have been under 1:29! Oh well.   

Why did I finally succeed at sub-90?

My theory is that I finally accomplished my goal because I have been running higher mileage this spring. I’ve averaged around 60 miles per week in my Boston training, and have peaked at 65 miles per week. I am a runner who frankly does better when running a lot of miles. Less is not more for me. I saw a major breakthrough in my marathon time when I increased my training mileage from an average of 42-45 miles per week to an average of 52-53. Then I had another big PR when I started averaging 60+ miles each week. I am probably lucky that my body can handle that kind of training load and that I have the time to fit all the miles in – not everyone can, or wants to, of course. Last fall, when I first started trying to break 90, my weeks averaged around 55 miles and I only broke 60 miles per week twice in my 12-week training plan. That may not have been enough to accomplish my goal, even though I was doing way more half marathon specific pace work. Anyway, that’s what I think!   

Now it’s on to Boston! I was aiming for a 3:15, but this half time indicates I could be a little faster than that. Of course, Boston is a tough course and the weather is unpredictable at best…. But I am feeling optimistic and excited! 23 days to go!

  1. Congratulations! I loved reading this blog, especially since I can relate to that sub 90 goal. I can’t believe how much you were able to speed up at the end. Truly remarkable. Seems like perfect pacing, especially with that monster hill. Honestly that hill is why I have only run this race one time in my life. It’s also great that you figured out what works for you in training. For some runners, high mileage is truly a game changer and it’s great that your body is able to handle that.
