Jane McGuire is Tom's Guide's Fitness Managing 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 she 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 six marathons — the London Marathon five times, and the Berlin Marathon once -and is still on a quest to tick off all of the marathon majors. Her marathon PR is 3:30, which she ran in the New Balance Supercomp Elite V5's, but she also spends a lot of time talking about 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 spaniel, Toby.
