My second run of the year was the Bangkok 21k park Run 2025. This was my second time participating in this run, having done it in 2024, too. This is one of my most favourite running events in Bangkok.
Like before, the run was in the scenic Suan Luang Rama IX park. Like last time, it was raining the entire week, but surprisingly didn’t rain on the morning of the race.

Since this is a race I did twice with a gap of 1 year, it is a good opportunity to compare the metrics.

As you can see, I was able to shave almost 10 mins off the race time.


As you can see, there’s an improvement of approximately 1 minute for each split, consistently. This time, I was able to maintain sub-6 minute splits almost throughout the race.


This time, I seem to have much less time in Zones 3 and 5 and more time in Zone 4. Also, post-workout recovery seems to be much better.
Overall, I am quite pleased with the improvement in performance and hope to improve more by next year.


I think they gave me the 21k medal by mistake.
