Runner-in-Chief

Jeff is Runner-in-Chief for Runner’s World and the director of product testing. He has tested and reviewed running shoes, GPS watches, headphones, apparel, and more for nearly two decades. He regularly tests more than 100 pairs of shoes each year, and once had a 257-day streak running in different models. Jeff can usually be found on the roads, racing anything from the mile to a marathon, but he also enjoys racing up mountains and on snowshoes. When he’s not running, you’ll probably find him hanging from a ladder making repairs and renovations to his house (he’s also director of product testing for Popular Mechanics).
