Inside the Stryd Performance Lab: Testing the Adizero Evo Prime X Ahead of Charlie Lawrence's Historic 100K Run

Watch Charlie Lawrence’s Shoe Test Before His #2 All-Time 100K
On August 26, the Adidas Chasing 100 event took place in Italy. The event was a time trial featuring five elite ultrarunners aiming to achieve the fastest known time for 100 kilometers with the help of Adidas’ latest running innovations.
One of those runners was Stryd athlete Charlie Lawrence, 50-Mile World Record Holder and now the fastest American ever over 100 kilometers.
Before chasing history, Charlie came to the Stryd Performance Lab for a shoe test. Just 13 days before the 100K attempt, he visited Stryd HQ in Boulder to confirm the Adidas team’s data on which version of the Adizero Evo Prime X made him most efficient.
“I’ve always preferred a stiffer rod for the aggressive flick, but numbers never lie. I wanted to make sure I had the most optimized pair on my feet to go after the fastest 100K ever. Huge thanks to Stryd for giving me more confidence going into the biggest running challenge of my career so far.”
