Went for a run in the evening to train up for the upcoming army half marathon. I underestimated the evening sun, it was still extremely hot at 5:30pm. Thankfully, the park has many tall buildings nearby to block the sun. Initially, I had aimed for just a 50min run. But half way through I decided to endure through and finish the 9km instead. Unknowingly, I also ran faster than usual. Usually I would run at a pace of 06:30min/km for this kind of distance.
