After some easy days of recovery from Tempo workouts on the bike, this week’s training marked the point of switching the focus from building VO2max to pushing up my lactate threshold. It also marked a turning point in my road to recovery which has enabled me to find my feet again! More of that later, but first, reading back I realised I glossed over a proper definition of lactate threshold; which is an important metabolic marker and determinant of performance. So let’s look at that now.
Think of this as the top (sustainable) speed that will get you to your destination. Now let’s imagine there’s a shiny new electric car sitting in the driveway. Spec says it can hit a top speed of 145mph. Well, aside from it being illegal and reckless to drive around at that speed…it is simply not sustainable, it would quickly run out of charge and grind to a halt. Rather it would be much more sensible to dial that back to a (legal) speed the battery charge will sustain for a lot longer.
Much like your running; if you blast out the door and exceed your top sustainable speed, your batteries will soon run down. This is the point where blood lactate accumulates faster than you can process it. You’ll recognise this as your legs starting to feel heavy, accompanied by an intense burning sensation, ultimately forcing you to slow down or stop altogether.
