The first half of the run was quite easy. From time to time, I high-fived people on the roadside, feeling like a hero, and my vanity was greatly satisfied. However, the second half was a torment for me. After crossing the Yanwu Bridge in Xiamen, my ankles, knees and soles were particularly uncomfortable. It hurts there and here. However, I didn't take it to heart and kept running. At 35㎞, the pain in other places slowly disappeared, but the pain in the outside of the knee became more and more. It hurts to run one step, and at that time, I was not physically strong enough, so I ran while walking. When I stopped to get supplies, my knee hurt badly. At this time, I am not walking, running or sitting. At that time, I regretted taking part in the marathon very much. I have always blamed myself and regretted it, and many negative emotions have impacted me. I once thought about giving up the game. Later, the little friend I picked up on the road came to encourage me and said that I would accompany you for the last two kilometers. So, I walked to the finish line step by step with my sore knee, and the finish time was 5 hours 19 minutes. At that time, I was still very proud, excited and moved.
