Lumen is a metabolism tracker and can do clever things like analyse your fat/carb burn via breathing. The app is tailored for either dieting or performance sportspeople and, FWIW, Chris Froome swears by it on Lumen’s website. #QuantifiedSelf. I’ve been using one for several weeks and have a more detailed review scheduled for later this year.
Lumen is on sale until 31 January for $299/£299 (rrp$349/£349) BUT…
I’ve got an ADDITIONAL code for readers of this site. That code is THE5KRUNNER30 and that will give you an EXTRA $30/£30 off. ie both codes work together as the image to the right shows.
This gives a special sale price of $269/£269
You can get a further 10% off if you order two (ie 3 deals together in one).
Order HERE, or click one of the Lumen images.
