Weekend 15k Run

The weather is absolutely beautiful this morning.
I am currently preparing for a half marathon on October 25th. It has been a while since I ran 15km; once I passed the 10km mark, my heart didn't feel like it was going to explode, but my legs felt heavy—or rather, my body just wouldn't cooperate. I felt more exhausted than my heart rate would suggest.
However, I had a great run. I hope I can complete the half marathon! ^^
