上周，有个朋友早上跑步绊倒了，膝盖被磕破了，脚踝也扭伤了，肿的像个馒头。在医院简单处理后，让回家休养，已经过去五天了，还不能跑步。
（ECNS） -- A 4,285-meter canal carved into a karst cliff in southwest China’s Chongqing has become a social media sensation, attracting photographers and hikers to Qianjin village in Wulong district. Nearly 1,000 meters of the canal runs flush against a precipice hundreds of meters high, with spring water still trickling through its channels. Villagers began hacking the waterway out of solid rock in 1999 using chisels and hammers, completing it three years later to bring water and electricity to mountain communities.
From lifeline to hiking destination As modern irrigation improved, the canal’s role faded, but its dramatic setting has turned it into a magnet for outdoor enthusiasts. "The trickling sound of spring water runs on one side and a green canyon on the other. It was well worth the trip," said Liu Zhengchun, a hiking enthusiast from Chongqing, who came with friends after watching videos shared by bloggers on social media. He noted that the narrowest section of the canal is barely wide enough for one person to pass by bending forward, and that the chisel marks left by the builders remain clearly visible on the rock face. A waterfall near a hydropower station along the route has also become a highlight.
Builder-turned-guardian Builder Li Wufeng, now in his 60s, continues to maintain the canal and volunteers as a safety monitor as visitor numbers grow. "In the past, I was basically the only person walking on the canal," Li said. "Now more and more young people come to explore, hike and take photos. On peak days, I can run into more than 200 visitors."
Local government eyes tourism development As the site's popularity grows, authorities are paying increasing attention to outdoor safety and ecological protection. Local officials are planning a loop-shaped scenic area that integrates sightseeing, experiential activities and leisure, with supporting facilities including a parking structure, a visitor center, cliffside plank roads and a glass observation deck. The goal is to give the cliffside canal, once a hard-won lifeline for a mountain village, a renewed purpose in the era of cultural tourism.
。他绊倒的原因，是公园的塑胶跑道上鼓起了一个大包，据说很多在这里跑步的人，都曾被都绊过。
B | 这事，到底是怪路维护不及时？还是怪人不小心？
三个问号第一，跑道为什么会出现质量问题？跑道拱起变形，施工有问题？跑道的基层处理不到位，路基压实度不足，雨天积水渗入底层，跑道表层就会鼓起开裂。再加上夏季高温暴晒，塑胶面层热胀形变，边缘鼓起、接口起翘，确实容易变形。第二，为什么长期无人维修？出问题不是最可怕的，最可怕的是出了问题没人管。跑道拱起变形显然不是一天两天的事，但长期无人过问，直到有人因此受伤。第三，为什么不设警示牌？哪怕修不了，至少立个牌子、拉个警戒线，提醒跑者绕行。
C | 什么都没有。公园跑道本来是“惠民工程”，可不能变成“害民工程”。
D | 普遍现象有人可能会说：“就一条跑道出了问题，至于大惊小怪吗？”还真不是个例。今年7月，河南某地新区体育场某湖旁边的跑步道，路面维护留下凸出的大钉，导致一名孩子跑步时摔伤。
E | 某地体育公园天桥路面破损严重，“从建设投用没几天就路面破损”，被市民称为“豆腐渣工程”。
F | 还有某县花了520万元改造的体育场，刚完工试用阶段塑胶跑道就出现多处开胶、表层脱落，踩踏后底层材料外露。
G | 当地网友拍下视频，跑道像被撕开了一道道口子。修跑道是为了让人跑步，现在反倒让人摔跤——这钱花得冤不冤？该谁负责？从法律上讲，公园跑道的管理者，应该是城市管理的相关部门。《民法典》明确规定，公共场所的经营者、管理者未尽到安全保障义务，造成他人损害的，应当承担侵权责任。公园跑道出现安全隐患，管理者应当设置警示标志并及时维修。不修、不警示、不处理，出了事就要担责。今年7月，北京房山区一个公园的座椅老化失修导致老人摔伤，法院就认定公园管理方未尽到安全保障义务，判决承担赔偿责任。这不是“你倒霉”的问题，这是管理者的责任问题。跑者怎么办？作为普通跑者，我们能做什么？第一，跑的时候多留个心眼。夜跑时注意脚下，尤其是熟悉的路段反而最容易放松警惕。这次摔伤的跑者就是在自己常跑的公园出的事，最熟悉的地方，突发变化，往往也最危险。
H | 第二，发现问题及时反映。看到跑道破损、拱起、有异物，拍照发到本地政务平台或12345热线。早一天反应，可能就少一个人受伤。第三，受伤后保留证据维权。拍照、录像、留好就医记录。公共设施管理者有安全保障义务，该承担的责任不能让他们推掉。写在最后跑步是为了健康，不是为了受伤。一条好跑道，应该是跑者的“朋友”，而不是“陷阱”。
I | 修了跑道没人管，比不修更可怕。惠民工程，不能变成“害民工程”。跑者的安全，不该靠运气来保障。
