Marathon Milestones

The four-minute mile and the ten-second hundred-meter dash are iconic milestones in running, but the two-hour marathon has become the latest frontier. With record-breaking performances from athletes like Dennis and Eliud, the possibility of running a marathon in under two hours is tantalizingly close. The distinction between a world record and a world best highlights the nuances of competitive running, especially with initiatives like Nike's Breaking Two project pushing the limits of human potential.
