World records are set to be broken, and history-makers in athletics often remind their counterparts and expectant enthusiasts of this.
Last Sunday, Kelvin Kiptum reminded the athletics world that the best marks must fall. At 23, Kiptum shattered a one-year-old marathon world record at 2:00:35. He shed off 34 seconds off the previous 2:01:09 mark set by the legend Eliud Kipchoge.
