Eindhoven Marathon 2026 – Back from years of injuries: 3:13 in my daily trainers (with a cold)

TL;DR: After years of on-and-off injuries, I rebuilt with strength work and patient volume, developed calf issues in my super shoes, raced in my NB 1080s with a cold, hung on to the 3:15 pace group with a twinging calf and finished in 3:13. That's a ~9-minute PR.

Background

I started running seriously about 8 years ago, coming from football (soccer) and a few years of tennis. During Covid I ran a lot and got into the best shape of my life: 80–90 km weeks that translated into time trials of low 17s for 5k, 1:02 for 10 miles and 1:22 for the half.

So naturally I kept running longer and harder, which eventually led to a long series of injuries that made consistent training really difficult. I did run a marathon in 2022 on low volume (3:22), but after that the injuries kept coming. I managed around 1,000 km a year, but never consistently.

Training

About six months ago things started to turn around. Two things changed:

• I started doing bodyweight strength routines, a good part of them single-leg.
• I stopped chasing goals and focused purely on building volume, letting how my body felt decide whether I needed rest or could add a bit more.

From May my volume climbed to 40–50 km/week, with 200+ km months in June, August and September. Over the last 12 months that adds up to 1,631.5 km, or 31.4 km/week on average, most of it from April onward.

A fall marathon started to look realistic, so I signed up for Eindhoven, with the option to cancel. I kept training through our summer holiday in Croatia. Getting up at 7:00 to run in 28–29°C along the coast wasn't always fun, but I got it done. After the holiday the focus shifted to extending my long run.

Shoe trouble

This is where the problems started. I do most of my running in the NB 1080v14, but some in the SC Elite v5. Whenever I extended a run or picked up the pace in the SC Elite, I got calf issues, several times. I figured the shoes had too many km on them (~400) and bought a new pair. Three weeks out, during my longest planned long run (30 km), I had to stop halfway in the brand-new SC Elites. Calf again. I took an easy week, mostly in the 1080s.

I decided the marathon only had a chance in my trainers. That was a tough pill to swallow, because the difference between the two shoes is huge for me: about 10 bpm at the same pace. In the comparison below, a 4:30 km cost me 131 bpm in the SC Elite and 141 bpm in the 1080v14. But the 1080s were the only realistic way to the finish line.

I still wanted some reassurance that my calf was OK and that I was somewhat ready for the distance. So 11 days out I ran 18 km with 10 km at marathon pace. It went well, and the start line was back in sight.

Pre-race

Then came the second setback: a few days before the race I caught a cold. It lingered, so I took it day by day. On race morning I was still doubting whether to start, but the symptoms were above the neck, so I decided to go for it, accepting a bigger chance that I'd have to slow down or drop out.

As the morning went on I felt better and better, and in the start corral I felt pure joy. The start was delayed by 10 minutes, but I couldn't have cared less. Being a runner again, in a corral at a big event, surrounded by like-minded people with anticipation in the air: I hadn't felt that in a very long time. Absolutely fantastic.

Race

The plan was to race by heart rate:

• 0–10 km: under 148
• 10–20 km: under 154
• 20–30 km: under 158
• 30+ km: HR matters less; push or hold depending on how I felt

I expected that to work out at around 4:28/km, which is A-goal pace.

I started a bit behind the 3:15 pace group, planning to use the first few km to gauge the form of the day. The first km went well, but despite feeling good, my HR crept up faster than I wanted. By km 4 it was already at 149, over my 148 cap, and it stayed around 150 for the rest of the first 10 km.

Around km 6 I caught the 3:15 pacers. With my HR on the high side and some very windy stretches, I decided to tuck in for a while. That "while" turned out to be a long time. I was running slower than planned (around 4:34/km on my watch instead of 4:28), but my HR still sat steady at around 150. That was within my caps for km 10–30, but higher than I wanted for that pace, so I stayed with the group.

Around km 24 I started thinking about picking it up. The moment I thought it, my weak left calf started giving small twinges for the first time. I took that as a clear sign not to push, stayed in the group, shortened my stride and hoped it wouldn't get worse. You can see it in the splits: km 24 was 4:43, my slowest km until the very last one.

The km ticked by. The calf didn't go away, but it didn't seem to get worse either. Around 30 km I accepted that this was the most I had in me and that I'd try to hang on to the 3:15 pacers until the end.

From there it went downhill fast, even if the splits don't show it at first. The pace held at 4:30–4:35 until km 38, but the cost kept rising: my HR went from 155 at km 30 to 162 at km 37. By km 33 I was working really hard just to reach 35. After that it was a fight for every km. The calf didn't get worse, but everything else started protesting: hamstrings, quads, the other calf, basically everything.

I focused on one km at a time and reached 40 km in an ever-shrinking group. My pace had started slipping from km 39 (4:39, 4:40, 4:40, 4:45), and over the last 2 km I watched the pace group pull away from me, meter by meter. I fought for everything I was worth and finished about 40 m behind the pacers in 3:13. Given the circumstances, it felt like the maximum.

Technically a BQ, but without enough buffer to actually get in.

Post-race

After the race I could barely walk, but I was very happy and satisfied. A week later the soreness is gone and I'm already making new plans. A spring marathon would be great, and the bigger goals (a BQ with a proper buffer, maybe even sub-3) keep calling.

Takeaways

• Strength work (especially single-leg) plus building volume by feel finally gave me consistency: 1,631 km in the last 12 months, versus ~1,000 km/year in the injury years.
• Super shoes aren't free speed if your calves can't handle them. Racing in my trainers cost me efficiency, but it got me to the finish.
• Tucking into the pace group when my HR ran high gave me almost even halves (1:36 / 1:37), even with a calf and a cold.

Thanks for reading. Any tips for building toward that next goal are very welcome!

Great time with such low weekly km

[u/CarsnBeers → u/Puzzled_Operation374]

No kidding. Well done.

[u/Bennassi3]

Adding age, max HR and LTHR would be nice, to have some context with the HR data you provide

[u/zaratoestra → u/Bennassi3]

age 43, max HR estimated at 178-180. No measured or estimated LTHR, although I would guess it is somewhere around 158-160

[u/sweek0]

Well done! That’s especially impressive in 1080s - those are very comfortable but not very fast shoes.

I’m not sure I get your comment about this being a BQ but one without a big enough buffer. You mention you’re 43 so the standard is either 3:05, in which case you didn’t qualify, or 3:35, in which case you easily got it.

[u/zaratoestra → u/sweek0]

Well, I am 43, but will be 44 before Boston 2027. Since registration has already closed, a time now will be used for 2028. I will be 45 by the time Boston 2028 happens and therefor the time I need for qualification = 3.15 minus cuttof (which i certainly won't make)

[u/sweek0 → u/zaratoestra]

Right makes sense. Hope you get another chance in spring.
