9.20.2019 - 11 best GPS cycling computers so you can train smarter - The Independent
Awesome battery life is the big selling point for this one. It claims up to a whopping 48 hours thanks to its use of a 2.7-inch black and white screen rather than a power-sapping colour one. It will pair with your phone and ANT+ sensors and you can customise the array of data fields you see on-screen. Unusually, this solid little unit can be mounted in either portrait or landscape format. It feels solid enough to stand a few bumps and knocks, making it a good choice if you enjoy riding trails.

"A lot of these races, the courses aren’t marked. That makes it fun and a little bit of an adventure. Kanza’s not marked. So, I use this Lezyne GPS; you download the map, you get the turn by turn, and you follow the breadcrumbs along the course and hope you don’t get lost in the Flint Hills." - Alison Tetrick
