Sub2Hrs

Countdown to the first Sub2Hr Marathon. The first dedicated international research initiative made up of multidisciplinary specialists.

Based on what is presently known, whoever breaks the 2 h barrier will have a favourable genetic profile (yet to be determined), an outstanding running economy and small body size along with chronic exposure to high altitude and significant physical activity early in life. Current trends also suggest that an East African will be the first to break the 2 h barrier.
