    Muscle fatigue, not cardio fatigue...

    Whenever I drop the hammer for about 20-30 minutes, my leg muscles start to get fatigued. My heart and lungs are fine. What is the best way to combat this?

    I have the same issue, I would think the best way would be not too go too hard on the bike and just put in gobbles of miles. Though I could be wrong

    there is only so much muscle glycogen. Do you mash more than you spin?

    as others have said, higher cadence is the way to go. Chances are you are nowhere near the 100rpm mark. get better at higher cadences.

    The other thing that I do, that I am sure to be flamed for, is gym workouts specifically targetting muscular endurance.

    Limit your rides to 20 minutes

    Spinning faster should help.

    Often, with changes in training, you get out of balance between the cardio systems and the muscular systems. It often takes a couple weeks to balance back out, and it can be a sign that your aerobic engine has taken a fitness leap and your legs just need to catch up, which is a good thing

    This usually happens when I'm at around 100 RPM, actually. My average cadence for the entire ride was 91 (brought down due to a few climbs and descents). I usually spin it at around 100-110.

    If there's no specific way to target this (2x20's, etc), I suppose I'll just keep at it at work through it, try spinning faster. Thanks guys.

    I don't think it's a cadence issue. It's a power pacing issue. You are riding at a power output that is close to your "threshold". You can either back off, or break it up like you suggested with 20+ minute intervals.

    My legs get fatigued after 20-30' at FTP too.

    You can't combat it, you just get faster.

    i don't think anyone here would call 100 rpm's "mashing".

    Also increase your long distance rides at a moderate pace, do hills, and intervals. Mix up the intervals like 5 or 6 5 minutes for a couple weeks, 3 or 4 10 minutes for a couple weeks, and 2X10's.

    You need endurance as well as power. The long rides build you up for the interval work.
    You're just trying to start an argument to show how smart you are.
