Lights on the track are helping runners shatter world records

Advancements in shoe technology have garnered headlines and stirred controversy recently for the way they boost performance. But three vaunted world records have fallen in recent weeks thanks in part to wavelight technology, a system of flashing lights that helps runners keep pace with record times.

The event was organised by Cheptegei’s NN Running
