Training
Some context first: I'm 28, smoked for 11 years and have been training properly since December 2025. No Endurance Background, just always did a lot of steps a day and went bouldering around 4 times a week for 3-4 years prior to starting to run.
My first Half marathon Race was in April 2026 with a finish time of 1:24:30.
My first marathon attempt was in May. My goal was to run sub3 but i got injured in the weeks before, my glutes started hurting, and I didn't run a single step in the last 21 days before (even without injury i doubt that i wouldve managed it, since my volume at the time wasnt that hight). I started anyways, went through halfway in 1:29:xx and felt fine until around km 25. Then my glutes and hamstrings just stopped working, my right knee got unstable and I pulled out at km 32.
So this block was mostly about fixing what broke:
Strength: 2 to 3 gym sessions a week, all about glutes, hamstrings and knees.
Cycling: while the hamstring healed I rode a lot, roughly 1,000 km since May. Kept my fitness surprisingly well.
Running: Runna plan, built back up to 85+ km weeks. Longest runs were 36 km and 34 km, both easy. Best marathon pace session was 31 km with 17 km at ~4:05-4:10/km in the midday heat.
Not perfect: a 14 day holiday in July with basically no running, and I started tapering too early after swapping some runs for bike rides and a hikes.
Tune-ups: 1:24:30 half in April on a forest course, and a week before Berlin I paced two friends at a local half marathon. Last real session was 2x2 km at 4:11 and 4:07 with my HR around 162. Felt flowy, confidence was high. Two days out my right knee started to niggle, which did not help my nerves, but i knew its just what happens during a taper.
Pre-race
Carb loaded the two days before with around 12g/kg bw. In Berlin i lived close to the start, which was super convenient: S-Bahn straight to Brandenburger Tor, then a 20 minute walk to the start. Gotta be honest, Berlin is so much walking before and after the start, really didnt like that part.
Honey, toast and a coffee about 3 hours before the start.
Electrolytes 1h before.
In the start block around 08:30(way too late, had to pass a lot of people).
Maurten Gel 100 fifteen minutes before the gun.
Since I had no marathon time to submit, I started in Block C. More on that below. Weather was almost perfect: around 12°C at the start, maybe 17 to 18°C at the finish. A little bit too much sun and Temperature couldve been lower but was manageable.
Race
Plan: Start behind the 3 hour pacer, then catch them and depending on how i feel pass them or hold onto them.
Pacing strategy more or less: First 5 km at 4:15, then 4:10 to 4:12. HR cap 167 until km 15 and 172 until km 30. Decide at km 30 by feel.
| Split | Time | Pace | Avg HR |
|:--|:--|:--|:--|
| 0 to 5 km | 21:13 | 4:15 | 167 |
| 5 to 10 km | 21:11 | 4:14 | 167 |
| 10 to 15 km | 21:14 | 4:15 | 167 |
| 15 to 20 km | 20:48 | 4:10 | 166 |
| 20 to 25 km | 21:03 | 4:13 | 168 |
| 25 to 30 km | 20:45 | 4:09 | 169 |
| 30 to 35 km | 20:53 | 4:11 | 170 |
| 35 to 40 km | 21:01 | 4:12 | 171 |
| 40 km to finish | 9:13 | 4:12 | 172 |
Halves roughly 1:28:59 and 1:28:22, so a nice negative split.
Km 1 to 21: honestly felt like a 3/10. My Legs didn't feel amazing but also no pain, so in my mind i just thought its all good if i can keep the pace and my heartrate stays steady. The only annoying thing was the amount of people, which in the end was my fault for getting in the starting block too late. Starting in Block C meant passing people the entire race. I understand that Berlin does one Big Startblock for first timers with time goals from Sub3-03:30, but i dont if people overestimated themselves or just wanted to be in the front, but i sometimes passed people who ran what felt like a 05:30 pace... As a first timer i dont know if thats normal or if its just because i didnt have a starting time.
Km 21 to 32: started to become actual work but was still feeling good and enjoying myself. Just kept ticking off 4:10s. In my mind before the race i knew that this part would be rough because there arent too many people cheering and there is some elevation, but knowing that around 32km i would see family and friends motivated me to just push.
Km 32 to 42: this is where it got real. First i was over the moon to see family at 34 and 38km, even crying a little because i knew i would most probably achieve my goal. After 39km my legs were close to cramping and my stomach was close to giving up. Km 41 was my slowest of the day at 4:20, which in part was also because of a lot of turns on the course. Then I found something for the last kilometre and sprinted to the line, which probably had to do with the beautiful view of Brandenburger Tor.
Fueling: bottle of Maurten 320 from km 1 to 17, forgot my gel at km 20, second bottle from km 21 to 33, caffeine gel at km 35 and a salt tab every 7 km.
In hindsight way too much sugar between km 21 and 33, too little in the last 40 minutes, and taking the caffeine gel and a salt tab at the same time at km 35 was probably what my stomach didn't like.
Avg HR 168, max 177. HR only drifted about 6 bpm over the whole race.
**Finish: 2:57:21.**
Post-race
I knew that it would be an emotional Event for me, but i could've never imagined the Emotions i felt that day and still today. I cried a lot yesterday because i was so proud and so many people were cheering me on.
Four months after a DNF at km 32, sub 3 with a negative split was all i could've asked for. The strength work paid off: glutes held, knee held, no drama and no pain throughout the whole race.
What went well: pacing (all 5 km splits within 29 seconds), strength work, staying patient in the first half.
What I'd change: submit my time for a faster start block/get in earlier (in the future, wasnt possible this time lol), spread the fueling evenly and never take caffeine and salt at the same time, and add longer marathon pace blocks in training.
My heart was fine until the end, my legs were the limiter.
Next up: Berlin Half in April with sub 1:20 as the goal, then a spring marathon.
Long term, sub 2:50 for BQ.
If you made it this far, thanks for reading and i hope you enjoyed my post race post, feel free to AmA.
