Deep Dive Digest #31: Introducing Quick Reads, for the Time-Crunched Athlete

Deep Dive Digest Files HEADER

The Deep Dive Digest is a weekly digest of the site’s key news. You can subscribe for free to an ad-free version, automatically emailed to your inbox. Sign up below.


Quick Reads are a new format that I’ve trialled on the5krunner.com for a month. Each read gives you the facts of a story in under a minute, with no padding to wade through. Look on the site for the QUICK READ label in the title, they won’t normally be added to this newsletter in the future. But they are today…

This issue collects a week of them in four groups: Garmin news and deals, sensors and health, strength training, and cycling.

The range is wide. A $150 clip-on sensor sets your next lift using Velocity Based training, the only way to properly assess muscular strain during strength work, while a $20,000 chair vibrates smartly to boost resonant breathing. A sensor worn on the side of the head claims to beat Apple Watch on heart rate, and a Whoop patent explains how it estimates VO2 max without GPS or power.

Quick Reads are summarised stories I don’t have time to cover and include a wide range of topics like new features, kickstarter launches, noteworthy price drops, and company financial news.
