Houston Marathon | 2:17:44 | 12th Place Overall

I've got a lot to say and share about this race, but I'll try and keep it as concise as possible.

It's been 4 years since I've run a marathon that I've been remotely content with.

Most of my challenges have been getting to the start line without an illness or infection. It's been so hard to feel like I've been in the best shape of my life, then have the opportunity to fully express that just disappear overnight.

Then time passes, and you start to wonder where the limit is and how much more you can get out of a body that's been training hard for 16 years. I wondered if I could even mentally run the marathon successfully again.

But, last Sunday, though I didn't qualify for the Olympic Trials (2:16:00), didn't PR (2:16:59), and I didn't set a Course PB (2:17:33), I walked away with an experience that erases the bad luck and negative loop I've been stuck in for all this time.

I've shown myself that my goals are doable. I can run that big goal time/pace for 2 hours. Now, all I have to do is find out how I can clean up those last 15 to 20 minutes.

That's it. That's workable.

Here’s a snapshot of my Intervals.icu data tracking training metrics from July 2025 through yesterday’s 2:17:44 at the Houston Marathon.

Background-

Last July, I raced the Bix 7 in Davenport, Iowa for a few reasons. I wanted something meaningful to train for during the summer, I wanted to compete against a deep, tough field, and I wanted to support a historic grassroots race that still deserves attention. This was one of those events.

The race went poorly. I felt awful from start to finish and ran 36:55 (5:15 per mile), an effort that left me frustrated and honestly concerned. In the days and weeks that followed, I tried to figure out what had gone wrong. The conclusion was clear: I had overcooked myself between Grandma’s Marathon and mid-summer. I was burned out, and there was no fixing it by pushing harder. If I kept training aggressively, things were only going to get worse.

You can see that clearly in the early red dips in the chart. Those represent the energy hole I was stuck in. Between that race and my honeymoon about a month later, I kept running but pulled way back on both volume and intensity.

After that, I took five weeks that were essentially rest. I averaged about 10 miles per week, with several stretches of seven-plus days without running at all. I enjoyed my honeymoon, let my body heal, and never once regretted that decision.

Over the next 14 weeks, with a refreshed body and mindset—and working closely with my coach-I put together the best training block of my life. Nearly every week was better than the one before.

That blue line reflects my fitness based on accumulated training load. The green line represents optimal load. There were only two notable spikes early in the block: one marathon-pace long run and one very hot long run. After that, the green line gradually settles into the proper range, which suggests an ideal training stress that signals you are on track to get fitter.

On race week, the blue line sat right at the upper end of the ideal “fresh” range. That told me the taper was spot on from a data standpoint. Based on how I felt in the final two weeks, the data matched reality perfectly.

On race day, I executed my plan as well as I possibly could. The goal was sub-2:16 (5:11 per mile) and a third Olympic Trials qualifier. I hit halfway in 1:07:50 and held pace until about four miles to go. The final stretch was very hard. The wheels did come off a bit, but I kept enough together to finish in 2:17:44 (5:15 per mile), my third-fastest marathon and just 45 seconds off my personal best (only 1.5 second per mile difference).

Could a slightly more conservative start have produced a PR? Maybe. Maybe not. I had a clear goal, I committed to it, and I went for it. I have zero regret about that.

The bigger point is this: in July, I couldn’t hold 5:15 pace for seven miles. I certainly couldn’t hold 5:11 pace for 22 miles.

Knowing when to rest and when to push matters. Trusting that you can go from essentially zero to the best shape of your life in 14 weeks matters too. That process, when done right, is one of the most rewarding experiences a runner can have.

Finished my largest and final key workout of this Houston Marathon block this weekend, with a “race” in the middle.

The workout was 40 × 1 minute “fast,” 1 minute “float.” The idea was to alternate between slightly faster than marathon pace and slightly slower than marathon pace.

It’s a big workout - one I’ve done four times before: most notably before my PR in Frankfurt (2:16), twice before a top-50 finish at the 2020 Olympic Trials (2:18), and again before my next-best time at Houston (2:17) in 2022.

Across all five times I’ve done this session, I’ve averaged no faster than 5:10 and no slower than 5:12 per mile over 15.4–15.5 miles. Today was a 5:12 average, which makes me feel really good about where my fitness is right now. It’s in line with the best I’ve ever been, and not that I need confidence, but it is reassuring.

I ran the first 10 miles as part of the Frostbite Series 10-Miler at Forest Park. I finished first (though most of the other faster guys weren’t racing) and found out afterward that it was also the Missouri RRCA 10-Mile State Championships, which was a nice bonus that I only found out after I got home and was looking through the race results.

Thanks as always to for always putting inviting events during the usually frigid and less race-friendly winters!

I’m looking forward to putting all the pieces together in two weeks and finding out what I can do at one of my favorites races.

Had a good go at the Chesterfield Turkey Trot on Thursday - 15:08 for 2nd place. I’ll take it.

Frozen body aside, I managed to warm into it and negative split my way through with miles of 5:00 → 4:56 → 4:44 (4:52 avg).

Not my fastest road 5K ever, but it’s right in the neighborhood of my best, and that’s a good feeling heading into next week.

I get one more crack at the 5K before I stop acting like I'm training for this distance, at , where our crew is going after the team win. If things line up, I’d love to dip under 15 - and after this race, that feels extremely doable.

Sometimes it IS sunshine and rainbows



I’ve always enjoyed the feeling of coming to the track after many weeks / months away from it. That’s even better when you’re rolling off more “aerobic” work and that first session comes more as a surprise to the system. It’s that “hey, maybe I’m not the slow” feeling 🤣

Either way, training has been going well but still a ways to go to be marathon ready by January. a lot of miles ahead.

All smiles in New York 🗽

What an incredible time I had out on the course for the this last Sunday!

So so so much energy out there on an absolutely perfect day in the city. You can’t ask for more than what was given to the 60k + runners.

I’m thankful for a healthy body to be able to run a marathon (at a decent pace!) for training purposes, and to be able to spend a few days meeting with and cheering on many of the runners I coach throughout the city.

Nobody does it like NY. I understand why I heard “best marathon in the world” countless times over the last 5 days. Sure, it’s not the fastest, but what you get from this race is unmatched (or at least not yet experienced by me!).

This weekend wipes away the abysmal attempt of running the same race in 2021. I took a different approach. I chose to take it in versus try to take it all.

2:27:28 for 66th place (1:15:05 / 1:12:25 splits)

Took first* place at the Go! Saint Louis Halloween Half Marathon in Eureka yesterday morning with a time of 1:06:41, though I made a huge error around 2.25 miles into the race and completely missed a turn. My time would have been right around 1:10:00 if I hadn’t made the mistake.

The second place 10k finisher and the rest of the Half Marathon podium finishers made the same mistake but their mistake made their race longer.

This one of the many messy points of this race, but no need to go any further than that

The race was held right here where I live in Eureka, on roads and routes that I’ve run now thousands of times (and yet still missed a turn) so I was excited to try and get a win for Eureka. It’s kind of a silly thing, but I feel some sense of pride to have myself or any other Eureka resident finish atop any podium in Saint Louis races. There’s not that many of us out here!

Fortunately, I was able to make that happen, and despite the swell of emotions I had in course, I had a good run overall for where I’m at in training right now, and can hopefully use this as boost/support to my fitness as I get it going for Chevron Houston Marathon in 2026.
