lactate
The muscles do not have enough oxygen for aerobic respiration.
The burning sensation in a runner's muscles when lactate builds up is primarily due to the accumulation of lactic acid, which is produced during anaerobic metabolism when the body needs energy quickly and oxygen supply is limited. As lactate levels increase, it can lower the pH in the muscle cells, leading to acidosis. This acidic environment can stimulate nerve endings, resulting in the characteristic burning feeling. Additionally, the buildup of lactate indicates that the muscles are working at high intensity, surpassing their aerobic capacity.

Muscular cramp occurs when the oxygen demand by muscles is greater than what the body can provide. When the supply is less than the demand, the muscles start to undergo anaerobic respiration - this results in a build-up of lactate in the muscles. When the levels of lactate become too high, the muscles cramp.
Lactic Acid
The burning sensation in the muscles after strenuous exercise is caused by lactic acid. It is an acid that is formed when the body breaks down carbohydrates to use for energy when the normal energy stores have been used up. Muscles are building up lactate from anaerobic respiration. (apex!)
