Joshua Cheptegei from Uganda broke Kenenisa Bekele’s 16 year old world record in the 5000 m by 2 seconds after he ran 12:35.36 today in Monaco. That is an astonishing pace of 4:03 per mile for 3.1 miles. Here is the full video of the race
A new feature of the Diamond League races is the guided “light streak” that runs along the inner rail of the track based on a prescribed pace which the lead athletes have requested. While there are athlete pacers, the lights provide a steady feedback to the runners and prevent them from going out too hard and fading at the end which has been far too common in the recent past. The guided lights will likely lead to more controlled/stable pacing in record attempts in the future!
