To produce the energy needed, the body begins another process, which works in the absence of oxygen. Lactic acidâa byproduct of this processâlocks up your muscles, and because it is an acid it causes your muscles to experience that burning sensation.But lactic acid is completely washed out of the muscles within 30 to 60 minutes after you finish riding.o produce the energy needed, the body begins another process, which works in the absence of oxygen.

Lactic Acid and Fatigue. Lactic acid is rapidly broken down into a compound called lactate, resulting in the release of hydrogen ions. Your body can clear lactate by metabolizing it for energy, but when lactate production exceeds the clearance rate, it accumulates in your muscles and bloodstream.any people commonly, but wrongly, view lactic acid as a waste product that causes fatigue and muscle soreness. However, while lactic acid production often accompanies fatigue, it does not directly cause tired muscles, nor is it responsible for the muscle soreness you may feel a day or two after your workout.
