The weak point for most newer cyclists is lactate threshold. VO2max can be brought pretty close to maxium in about a year of good training, but unfortunately it takes years to build optimal LT. Hence, most riders are not even close to tapping the reserves of their cardio vascular system when lactic acid starts building up in their legs - hence affecting their ability to continue at a given pace. The solution is a higher cadence which more taxes the cardio system, and allows the legs to more readily dissipate lactic acid.
What is everyone talking about when they talk about lactic acid building up in the legs? I always thought lactic acid was what gave you a stomach ache after spicy food .
I was watching a bike race and the commentator kept talking about the lactic acid buildup showing its toll on x biker.
So basically what is it...how does it happen...and how do you control it (if possible)?
