    Lactic burn -- causes and solutions?

    I often get severe burning in my muscles even during moderate efforts. It is mostly in my quads, but sometimes also hamstrings, glutes, and hip flexors. On some days I feel really strong and can push hard on the climbs without pain, but lots of other times the burn limits how hard I can push, and even moderate efforts really hurt. My heart rate doesn't get too high, it's just that the burn is too painful and slows me way down.

    I haven't figured out what causes this on some days and not on other days. I don't know if it's nutrition, hydration, or something else. Sometimes I can attribute it to a lack of recovery from a previous workout, but not always.

    Has anyone figured out what causes this, and how to avoid it?

    I think you have it right. Lack of recovery is one of the causes. I sometimes have this issue too. For me, more training (and for longer periods) seemed to help.

    Also some folks have told me that a vitamin product called "sportlegs" can help. But I've never use it, so I can't comment on how effective it really is...

    Beta-Alanine Supplements ? Evidence Shows This Amino Acid Boosts Athletic Performance

    Baking Soda and Beta Alanine (Ethical Cheating or Ergogenic Aids)

    Also research TUMS
    TUMS for lactic acid???? - G.N.I.C.T. - The Running Forum

    Quote from link from article above:
    "The results of this study suggest that sodium bicarbonate may be used to offset the fatigue process during high-intensity, aerobic cycling lasting 60 min."

    Here's some new info someone posted on RBR:

    10 things you should know about lactic acid

    My experience definitely lines up with the conclusion:

    Lactic acid also is a powerful organic acid, and its accumulation can cause distress and fatigue during exercise. Athletes need both high intensity and over-distance training to improve the capacity to use lactic acid as a fuel during exercise and recovery. High intensity training develops cardiovascular capacity that reduces lactic acid transport to tissues that can use it as fuels. Over distance training causes tissue enzymes adaptations that increase use of fatty acids for energy. This helps slow lactic acid production from carbohydrates and to enhance tissues ability to use lactic acid as fuel.

    See, you can't do it on HIT or BASE alone. You need both to maximize performance.
