Nike is launching a collection of shoes and clothing called «EK Umoja» before the Berlin marathon scheduled for September 24. The clothing collection features 8 distinct pieces. These represent the legacy and mindset of the world champion according to nike.com. Kipchoge sees the collection as a representation of the work done with the running community. “Umoja means Unity in my native Swahili. This collection represents the work done together as a family and community of runners,” said the two-time Olympic marathon champion and marathon world record holder.
