Long Run today - I usually do this on Sunday, but we're going climbing tomorrow, so the run got moved to today instead.

Friday Tempo run - fortunately my back has recovered

High Base Run - I like these slightly higher pace, steady runs. Though I feel some stiffness in my back - I think I will take a day off tomorrow so I can prepare for Friday’s session properly

That was a really hard workout!

I usually rest on Mondays, but my new app decided to give me a workout today anyway… treadmill pace was nice and steady ;). Can't wait for tomorrow's tempo run - it looks monstrous!

Easy long run towards the end of the week 🏃 I had to change my running app yet again. It turned out my now-previous app can't recognize workout results unless they're sent as structured workout data - so if you hop on the treadmill and nail every exercise, it won't register, and your future workouts get affected as a result. On top of that, the app wasn't really looking at my heart rate. So that's app #3 now :)

Today drop set session was not easy at all. I chose treadmill to keep pace right 2 x 1km @ 4:05 followed by 2 x 0,8km @ 4:00 followed by 2 x 0,6km @ 3:55 followed by 2 x 0,4km @ 3:50 and finally 2 x 0,2km @ 3:40. Looking forward to more sessions like this one.

Yet another easy morning 🏃‍♂️

Just an easy morning run! Another 9km closer to my goal!

That was an awesome tempo workout session: 3 km at 4:25 min/km, followed by 2 km at 4:15 min/km and finally 1 km at 4:10 min/km. I’ve missed that kind of challenge and effort - thank you my new running app. Life without obstacles - real or made up - is just so boring.

I am finishing week 9 with a total distance of 41 kms. Good deload. This is also my first week with a new app - the first advantage I noticed that now on long runs and easy runs I do not have to keep some preset pace and can run whatever feels natural. I like that

Model doesn't matter, harness does! Yesterday I spent 170M input tokens analyzing and developing code, building and fixing markdown files, running workflows, and distilling knowledge out of data. It cost me around $5 - my usual day averages below $1. Over time I've used GitHub Copilot, Claude Code, OpenCode, Gemini (CLI and web), ChatGPT (web), and some models through Azure AI Foundry. Nowadays I mostly use independent model suppliers (EU and US based chips), though I still have access to Copilot and Azure AI Foundry. After all of that, it hit me: in ~90% of cases the model matters less than the environment (the harness) you run it in - and your skills. Almost every task, from writing code to translating to building knowledge, can be done just as efficiently with open-weight models. The performance gap between an average model and the top Anthropic/ChatGPT/Google offerings is around 20% (based on various benchmarks), but the price gap can be ~7,000%: ~$0.05 per million tokens (mixed input/output - what I actually pay) for open-weight models vs ~$3.85 (mixed) for Claude Opus 5. Based on my experience, the real skill is learning to understand and operate models. As human-like as they seem, they're statistical beings predicting the next token - they hallucinate and act weird when they lack proper context. Getting used to that and navigating it with good prompts and harnesses matters more than bleeding-edge models. Also, popular subscription models for LLMs don't make much sense in my opinion - it's much better to use them either for free (paying with your data) or pay per token, anywhere.

Another day, another run! It finally got cooler but tempo runs were not easy. I got my me PB for 1km though ! 🏆

It felt quite strenuous for an easy run 🏃 probably it is just hot right now🔥 🥵

Finally some workout that got me tired. Short, sweet and somewhat heavier

Half marathon, August B-race: goal sub-1:40, finished 1:42:41. Complete failure vs what I expected of myself. I trained diligently - 5x/week, no skips - and stayed on Trenara's (running app) plan start to finish. My effort was real. Trenara didn't deliver. I just deleted my account. Fortunately my data was synced to other running apps so now they can take over.

One last run before competition

Easy run - last one workout before hm

Monday endurance run 🏃

Long run at the end of week 7. This week I ran a total of 46.3 km but since the Ruda Śląska Industrial Half Marathon is next week it’s better to take it easy. 2 more workouts left!
