Kids from around the world stepped up to help National Geographic Kids set two Guinness World Records.
The magazine announced Tuesday that it set records for most people to run or walk 100 meters in 24 hours and for the most shoes collected for recycling.
National Geographic Kids collected 16,407 shoes, which were displayed at its Washington offices. Guinness World Records’ Mike Janela, who counted the shoes, called the effort “officially amazing.”
The athletic shoes — including donations from singer Taylor Swift and NFL quarterback Eli Manning (size 13!) — will be given to Nike Reuse-a-Shoe and turned into athletic surfaces, such as basketball courts.
Kids participating in the Marine Corps Marathon Healthy Kids Fun Run at the Pentagon on October 27 were among the running-record setters. But school groups, Girl Scout troops and individuals from as far away as India and Kuwait helped push the total to 30,914 runners.
