Garmin Forerunner 35 Watch (£103)
"I've been searching for the perfect GPS watch and wristband system for a while now, but I think I finally found my best bet in the Garmin Forerunner 35, which also allows friends and family to track your runs in real time. While these can be a splurge, I recently found out that you can purchase discounted renewed versions for basically half the price on Amazon." — Sarah Wasilak, editor, Fashion
