Tech: Wearable Lactate threshold sensor
A company called BSX athletics is trying to produce a product that you wear on your calf that would give you all the normal performance metrics (heart rate, cadence, pace, and calories burned), but it also claims to be able to measure your lactate threshold. Pretty cool bit of equipment if they can get it to work. It’s still in development and it’s on kickstarter. If you want to contribute, here’s the link for their Kickstarter page and the link to their page on the insight.
