Jane McGuire
Jane McGuire is Tom's Guide's Fitness editor, which means she looks after everything fitness related — from running gear and fitness trackers to yoga mats and sports bras. An avid runner, Jane has tested and reviewed fitness products for the past five years, so knows what to look for when finding a good running watch, or a pair of shorts with pockets big enough for your smartphone, running gels, and house keys.
Jane has run four marathons — the London Marathon three times, and the Berlin Marathon once, and is still on a quest to tick off all of the marathon majors. In the meantime, she’ll be telling anyone who cares about how her love for the Nike ZoomX Invincibles — her all-time favourite running shoe, or her ‘joy plan’, where she runs for happiness, not for PR’s.
Previous to Tom’s Guide, Jane worked for Runner’s World, where she co-hosted the Runner’s World podcast. She also presents on a YouTube channel called the Run Testers, alongside other running-mad journalists, where they review the latest shoes, kit, and tech. Her work has also appeared in Coach, Get Sweat Go, and Women’s Health.
When she's not pounding the pavements, you'll find Jane striding round the Surrey Hills, taking far too many photos of her puppy, Toby.
