“I did a lactate test – this is what it told me about energy, running speed and how to become a faster runner”

Looking to take your training to the next level? Then it might be time to get a lactate test, which can tell you all about your body’s capacity to work harder and faster. 

If I say the word ‘lactate’, your mind might immediately conjure up images of breastmilk, suckling babies and maternity bras. Indeed, when I announced that I was going for a lactate test to the rest of the Stylist team, I was met with some confusion. No, I wasn’t revealing some massive baby-related secret – I was going to get my blood tested to see what speed I should (and could) be running at.

The current obsession with biohacking has seen a massive boom in at-home finger prick tests. I’ve done everything from testing for my ‘fitness DNA’ (I’m not built for running, apparently) to food intolerances (gluten, dairy, alcohol…), and I know how dubious they can be.
