Race Report: We Run Seoul 10K and Season End Marathon (10K)

Been awhile since I wrote a race report, so I figured since the racing season is just about over, it's past time.

First, an addendum to last season - about a week after I finished my second half marathon, I read about this guy named Martin Rees. The guy is a friggin' beast. He's over 60 but still runs a 71 minute half marathon, one of many world records he holds in his age group. I wouldn't be surprised if he has all the age group world records from 1500m through marathon within a year or two (if he doesn't already). Anyway, I'm inspired when I hear about people getting super good at something they started later in life, so I read that article, got pumped up, and less than a week after my second half marathon, stupidly went out for a long run (~9-10 miles). With less than a km till I was home, all of a sudden, my left knee really started hurting, enough to make me stop running immediately and limp home. The next day, walking was very painful. I completely stopped running in order to let the knee heal, but after three or four weeks or so, it just wasn't getting any better. After a great deal of research, I decided that the cause of the pain was a serious muscle imbalance, and since resting doesn't fix entrenched muscle imbalances, that's why the knee wasn't improving.

For background, ever since I first set foot in Asia seven years ago, people have made fun of the way I walk. It's strange how some things are noticeable immediately to Asians but not to Westerners. Specifically, every Asian culture I've encountered has told me in some slightly different way that I walk like a duck. That is, feet pointed outward. I always just thought everyone walked differently, and that happened to be the way that I walked. But the more I looked into it, the more I realized that there was a reason I walked that way, and biomechanically, it's totally incorrect. Basically, duck feet are often caused by inactive glutes, along with other muscle imbalances. This is most likely the same reason my squat kept maxing out at a relatively low weight - I was overusing my quads, which are small muscles, and not using my glutes, which are huge, powerful muscles. If you develop this muscle imbalance long enough (like, my whole life), then you end up with what's called an anterior pelvic tilt, which causes all sorts of terrible posture problems and also sets you up for injury when you run.

Anterior pelvic tilt. Good for showing off the booty, but not much else.
So I decided I needed to fix this muscle imbalance before I got back to serious running. Basically as soon as I started focusing on working my glutes, my left knee started getting better. Ironically, my right knee started hurting quite a bit. But finally after a few months of dedicated work, both knees started feeling quite good, better than before, and I was able to get back to running again. The problem is not fixed - I looked back at footprints I left in the sand last month as I mindlessly walked along the beach, and was appalled to see the veritable duck prints trailing behind me - but it's much better than it was before, and I feel like I have a more solid base to work from now. I also notice duck walkers everywhere I go these days.

Enough of that for now. Onto the races!

Race 1: We Run Seoul (10K)

Last year, We Run Seoul was my first ever 10K, which I ran after a few months of Maffetone aerobic training and was more than pleasantly surprised to run in 48:58. This year, I came down with a serious cold, one of my first of the year, a week or two before the race. It was one of those annoying upper respiratory coughing colds, and I thought I might have to skip the race, but it was good enough by race day that I decided to run, despite doing very little running in the weeks leading up to the race. The race was crazy, chaotic, packed with people (about 30,000, I think). Having not done any speedwork, I actually felt like I was running fast, but when I crossed the 5K point at 25 minutes, I realized it was not going to be a great time. I finished in 50:01, which means I actually got slower over the last year. But it was fun, because it felt like a fast pace to me, and a 50 minute "base" 10K is not so bad.

Race 2: Season End Marathon (10K)

After We Run Seoul, I really wanted another shot at a 10K before the season ran out, so I signed up for a race over a month out, giving me some time to get ready. At the time, it seemed like a good idea. It was still beautiful fall weather, and I was excited to actually have some time to do a few dedicated workouts before the race.

Fast forward to the race, this past Sunday. It was 20F (-7C). Not only was it the coldest weather I've ever raced in, it was literally the coldest weather I've ever attempted running in. It's weird gearing up for a race wearing long pants, long sleeve shirt, light jacket, hat, and gloves. I ran around for 10-15 minutes before the gun, but just couldn't warm up at all. In fact, it took until somewhere between 1 and 2 km to be able to completely feel my feet. I also decided that for the first time since getting my heart rate monitor, I would run with the GPS watch but without the heart rate strap, instead relying on "feel". The great thing about heart rate training is also the worst thing about heart rate training - it's super easy to become addicted to constantly checking your heart rate. I was worried that going by feel without any training was a bad idea (you're not supposed to try anything new on race day), but I gave it a shot anyway.

The first mile came in at 7:15, way faster than the 8 minute pace from We Run Seoul. I slowed it down a bit the second mile (~7:45), because I was worried I had gone out too fast and was going to die of a side stitch before the halfway point, but I settled into a nice pace around 7:35, and felt pretty good, so kept going. At the turnaround, I looked down and saw 23:30 on my watch, which had me at PR pace. I picked it up slightly in the second half, and really started pushing in the last mile, and when I came out of the tunnel and into the stadium (the race started and ended in one of the stadiums from the '88 Olympics), I knew it was going to be good. I looked down before the final bend and saw I was at 46:10, and kicked as hard as I could to the finish, crossing in 46:28:61! A full three and a half minutes better than the previous race, and 45 seconds better than my prior best. All in all, a great race, and a great way to end the season.


So, where am I in terms of running? Well, I still don't really consider myself a "serious runner", although as my brother pointed out, I've run multiple half marathons, and am actively trying to improve my race times, so that probably makes me a "runner". :P Before this race, I squeaked my mileage up to a maximum of 21 miles per week, and got in 3.5 actual "speed sessions". Now I wonder what would happen if I could get up to 25-35 miles per week, and actually get through more than just a handful of speed sessions. 45 minutes definitely seems within reach now, but I'd really like to get down to 40 some day....

I like the shorter distances (5K, 10K), and will probably stick to those unless I get my mileage high enough to justify doing a half marathon. I like the feeling of moving fast, and 10K is a short enough distance that you feel like you're moving for sure. I actually really enjoy sprinting, too, and will probably throw in some sprint workouts for fun, but I have no idea if I can actually get official timings in sprint distances.

But even more important than the races, which are just arbitrary milestones that don't mean anything to anyone other than myself, it feels kinda awesome to be able to quickly cover the amount of ground that I can nowadays. The week before the race, I managed to complete my first "easy" run (i.e., average heart rate 147 bpm) 10K in under an hour, including warming up and some walking. When I started this whole thing a year and a half ago, I couldn't have imagined racing a 10K in less than an hour, let alone lightly jogging one. And during the race over the weekend, as I was flying next to the river on a brisk winter morning, I thought to myself, "Man, I feel like a better human now that I can run 6 miles in 45 minutes." Weren't we meant to be able to move quickly across the landscape? And as I returned my thoughts back to the modern era and headed down into the subway after the race, I realized that if I really needed to run another 10K right at that moment, I could do it. It would be painful, but I would survive. Just on my own, without water or fuel, wearing light clothes, I could totally run back in less than an hour. And that made me feel nice and warm and forget about my muscles already starting to get sore.

Why Korean Is Hard For Native English Speakers

A couple of days ago, as an experiment, I wrote my first blog post ever in a non-English language . It was an attempt to explain some of the reasons that Korean is hard to learn for native English speakers, so I figured I might as well try to write it in Korean. Those of you who actually read Korean can see how awkward the attempt was =). In any case, the post came from an email conversation I had with The Korean from  Ask a Korean , a fantastically well-written blog about all things Korea from the perspective of a Korean who moved to the United States during high school. Since I tend to geek out on language things, I figured I might as well post part of that conversation. An edited version follows. --------- Out of the languages that I've attempted to learn so far, Korean has been the hardest. I've done a lot of meta thinking about learning Korean, and I think there are a number of reasons it's difficult for non-Koreans (and especially Westerners) to learn: 1) Obvi

Stuttering in Korea

I had given up on English. It's my native language, but I figured after 30 some-odd years of disfluent speech, it was time to try something else. So I signed up for language classes in Korean, rationalizing that if I was going to try to teach myself how to speak, I might as well learn a new language along the way. This might seem completely insane, but when the prevailing theme of your conscious thoughts for multiple decades is some variant of "Why can't I say what I want to say?", you come up with lots of crazy ideas. For background, I've been a person who stutters for my entire life. I wrote about it on this blog a few years ago, so I think it's time for a followup. I've learned a lot since then, about myself and about stuttering, but in this post I simply want to give some insight into what it's actually like to stutter, and how my speech has changed over time. After the last stuttering post, the predominant reaction I got from friends was ei

Is It Worth It To Learn Korean?

Learning Korean as a non-Asian foreigner is an exercise in masochism. Note that I specify "non-Asian". Why does that make a difference? Simply because Koreans possess a deeply-ingrained belief that non-Asians are incapable of speaking Korean. The self-fulfilling prophecy of it is that since Koreans expect you to be incapable of speaking Korean, due to this mental block, they are likely to not understand you regardless of your proficiency level. Additionally, they won't respond to you with normal Korean like they would respond to an Asian person, because they assume you couldn't possibly understand. You will rarely ever have an opportunity to hear natural Korean, because Koreans simply won't speak it with you unless 1) they are open-minded and awesome (meaning they have probably lived abroad - thank you to all of you), or 2) they have known you long enough that they've gotten past the odd sight of a foreigner speaking Korean. In short, nearly every time you o
