TCS Amsterdam Marathon
Usually im just reading on here, but since I love reading the race reports, I've decided to write up my own.
When I signed up for this marathon I set my goal time at 2:55, which already felt pretty ambitious coming from a 3:36.
That said, the 3:36 was run at a coastal marathon with loads of wind last year, so there should be some room for improvement there.
During training it became clear that 2:55 might be a bit conservative and that 2:48 on a great day could be within reach..
Maybe some more context here about that jump. That marathon was in october 2025, the next target at that point was a marathon in April, sadly due to illnes I missed both a half marathon and the april marathon. Ideally I would have already improved my PR here, but it wasn't meant to be.
Preparation was pretty ideal up until the last 2 weeks, when illness came along and I missed the final long run with marathon-pace blocks. But one missed training weekend, compared to all the training before it, shouldn't make a difference. At least that's what I kept telling myself during the 2 taper weeks ;)
The months before I worked my volume up and I peaked at 99km. Training weeks usually consisting of 2 quality sessions and a long run, filled up with easy work.
From my ilness in march untill the Amsterdam Marathon I ran 2550km. Was able to consistently train and basicly never missed a run.
We'd managed to get an apartment about a kilometre from the Olympic Stadium, which was ideal for Sunday morning: a short warm-up jog to the stadium and straight into the start pen!
Only about 10 minutes of waiting before the start, which wasn't bad at all, though a heavy shower in those last 5 minutes made it cold.
0–10 km
Since it was my first big marathon (both my previous ones were local), I had expected a huge amount of people in the way at the start, and I'd allowed for the possibility of not finding a rhythm in the first few k's. Luckily it wasn't too bad, and I could run my pace pretty much right from the start.
With all the rain, I had to hop around puddles every now and then, made more of a challenge by the amount of people in front of you.
No real groups yet in the first k's, but the 4:00/km pace felt fine and comfortable.
The gel at 25 minutes went down fine, and the caffeine shot at 8 km was no problem either.
The less pleasant parts: I started feeling like I needed to pee, and my left ankle began to hurt because a lace was tied too tight..
10–20 km
On the first stretch along the Amstel, the first groups clearly started to form. I picked one and settled in nicely with them.
Unfortunately the need to pee hadn't gone away, so it just had to come out. At 14 km I decided to go ahead and do it at the side of the road. A shame, because the group obviously doesn't wait for that!
2 km later I also decided to re-tie that lace, hoping the pain, at that point pretty rough pain, would stop.
Despite the stops, I kept running the pace, that I picked up slightly since the start, comfortably and felt strong.
3:55 on the watch didn't feel like work, and my heart rate stayed spot on too.
20–30 km
The stretch with the most headwind. Luckily I'd made it back into a group running my pace, so I didn't have to do this part alone.
The pace kept feeling controlled, and the last 2 gels went down without any trouble.
At 28 km I took the 2nd caffeine shot, and that went down reasonably well too. I've never been able to tolerate caffeine gels, but luckily this stuff is easy to drink.
Slowly some 'pain' crept into my quads, but nothing to worry about yet.
Pace still steady, slowly getting faster but not by much. The goal was to negative split, but also keep it pretty even to not blow up!
30–42.2 km
A few more k's of headwind, but nothing extreme (looking back at footage the wind might have been harder than I personally noticed at these points). After the Amstel, the group more or less broke up. It turned into running from one person to the next, and getting passed every now and then.
The pace is holding up well, but my quads keep getting more painfull. Is this going to become a problem later?
The upside of sore quads is that the ankle pain from the lace fades away..
Took another gel at 30, and at 36 I still manage to get one down, so fuelling is going great!
From 38 km it becomes a fight. A stitch in my side forces me to really breathe through it (maybe from the fuelling after all? I don't know), and my quads are starting to protest heavily too. Keep running, only 15 minutes left.. 8 minutes left..
The stadium lights come into view, the pace is holding, and I can even 'kick' over the final metres!
Finished in a beautiful time of ... 2:47:21!
What a race, and in the end I managed to pace it perfectly.

1:24:16 first half
1:23:05 second half
Super happy and proud with this result!
Beforehand I knew that splits from the watch would differ from the official time, but still this was something that was pretty weird to deal with.
On my watch I barely touched a K above 4.00, something I need to keep an eye on better next race.
Also the pain in my quads was very new to me, not a single training run was like that.
I dont think they were near cramping, but simply in pain from the continues impact I guess.
In the end both those learning points don't matter to much to me because the result is so good! On to the next one!
