    So I've been riding about a month. At first I would get really really winded after a bloody mile. Aside from being really out of shape, I was trying to use taller gears and push like hell all the time.

    Now I can go for 5-10 miles before I bonk and my cadence is higher, like 90, but something changed... I don't much get winded now. I mean I do up hills and stuff, but what happens now is that my legs get weaker and weaker as I ride. I'll find myself not exhausted in a heart kind of way, but instead my legs will just get weak. I'll be down to the small chainring for a hill that normally would be done on the middle, that kinda thing. The legs become sorta non-responsive.

    Its a wierd kinda tired that I've never experienced before running. I guess its similar to the way my shoulders would get after a hard workout.

    Anyway, is this normal? Will this shift back and forth depending on the training I do, whether I get winded or leg-fatigued? I try to do alot of flat riding around here... but to be honest, there isn't alot. Its pretty hilly where I live.

    I have also experienced this when running before! My legs get all like sort of tingly, and i cant seem to push any faster. The aths season has just started over here, and i havn't experienced this yet but last season it was a main concern in the 400m. I have never experienced it while riding though.

    5-10 miles before you bonk? bonking is a physiological change in your body, the point at which your body has been depleted of glycogen (stored carbs) and begins to burn fat. which, leads to all kinds of mental stupor and confusion and flat exhaustion.

    you aren't bonking. you are simply running out of muscular endurance. spin shorter gears.

    That's about the time I rest for a few minutes, break out the Gatorade and start munching on a power bar. The most amazing part is, five minures later, I feel better than when I started out.

    Perhaps you are working above your lactate threshold, that is, the threshold where your body is no longer able to move lactic acid out of your muscles quickly enough in relation to how hard you are exercising. If that's the case, then you are not training your aerobic engine enough. The key is to ride longer distances at a more moderate intensity rather than mashing the pedals and going balls-to-the-wall for as long as you can.

    Also, as noted above, you are most certainly not 'bonking', unless you are exercising while maintaining a very low carbohydrate diet.

    Shorter gears seem to make it worse. Oh well, I'm sure this will all be different in another month.

    Have you been over doing it?

    Most "eddy experts" advocate no more than 3 or 4 hard rides a week, on alternate days, with very easy rides, or even rest days in between.

    If you've only been hammering for a month, I wouldn't worry too much.

    I'm not worried, I was just wondering if this was how people get tired on bicycles. Whether they get winded, or their legs get sloppy tired.

    I'm only winded for a minute or two, recovery brings that down nicely. However, when I get fatigued then my legs feel like jello.

    Are you eating enough to keep your glycogen stocked up? Do you eat within a 1 hour window after a ride to maximize your glycogen replentishment? If you are lifting and riding my experience is that overtraining comes earlier then I would have expected. Take a few days off, no biking, then see if you have a little more stamina.

    Also, if one month into riding, you shouldnt be concerned AT ALL with speed, or your big chainring. Spin and get those legs trained to handle the cycling movement. Regardless of previous leg strength or fitness from other sports, it takes TIME to get the conective tissue used to the stress of cycling. So no big ring for a few months (at least). This all helps too towards folks enjoying going for a ride and will often keep them riding since it helps to build a base founded on enjoyment rather then suffering. There is always time to suffer next spring. =)
    Its all downhill from somewhere.

    When you deplete glycogen you will burn protien lean mass.you need a flame via carbs to burn fat.

    I recently experienced this as well. At first, your cardio vascular conditioning was holding you back. You have improved that to the point where your leg muscle endurance is holding you back. Keep riding. Make sure you have light days and rest days planned in. You will be fine.

    You're going too hard for your level of conditioning. Back off on your exertion level and slow down some. If you are only able to do 5 to 10 miles, there's no sense in trying to set a speed record. Try maximizing the time you can ride, not the distance. I recommend you also get a heart rate monitor so you can better pace yourself and keep your heart rate around 80% of maximum. You'll get the most benefit from your workout and build cardiovascular conditioning more effectively.

    You mentioned initially that you go out and ride as hard as you can and you can go 5 miles. It sounds to me that your are riding at above your anaerobic threshold the whole way.

    I would suggest that you slow down and spin. "Spinning" is riding lower gears at higher RPM. It takes awhile for you muscles and circulatory systems to adapt to this but stick with it.

    Also, go out and ride relatively "easy" for a few miles say 5 miles. Then speed up but no so fast that you are going to burn out in only 5 miles. Also when you start feeling that you are getting beaten up, slow down and ride another 5 miles or so before finishing. Cycling is an aerobic activity and you do not have to kill yourself all the time to get into shape for it.

    The thing is that the way you are riding is probably counter productive. If everytime you go out on a bike, you beat yourself up, the bike will become an instrument of torture and you will give up cycling. It is better to go out and ride easier and enjoy at least some of your rides. Enjoyment will keep you at it longer then pain will. Don't get me wrong, pain has its place but it should not be the ONLY thing.

    Be sure you (and perhaps you already do this):

    1. Warm up slowly for a couple of miles

    2. Ride at a faster, but enjoyable, pace for several miles.

    3. Cool down fo a couple of miles by riding more slowly.

    Perhaps you are not giving your body a chance to easily make the physiological changes that come with high exertion. Maybe you are forcing your muscles into a mode for which they are not yet ready because you have not "warmed up" appropriately.

    And remember to always have fun!

    When I used to jog, I'd be huffing and puffing by the end. On a good hard run, my lungs would be kinda tired. But on the bike I don't really get that feeling. Usually it's my legs that just give out at the end of a long ride (or nowadays it's my freakin back giving out).

    In fact, I've been wondering how cycling and running compare in terms of their benefit to the cardio system.

    I think that I have been going too fast. Its funner to go faster, but I will slow down and ride longer.
