Standing for 10 miles with fixed hub? Is this a serious thread? I can't imagine riding down the street while standing on my fixed.. much less many miles.

Sorry bhop, I'll clarify:

I do not stand too much on my fixed gear, though I selectively stand.

On mountain bike I just stand and pedal.

again, sorry for deceptive words.

+1 This makes sense to me as well.

on bikeforums?
are you high, calrissian?!

Tell that to my co-worker who, at 21 yrs of age, is constantly going to the doctor for shin splints, knee problems and back problems. This guy ran long distances as a teen. Were talking 10+ miles a day and one time even ran 20+ miles a few times a week. He thought he was indestructible. He said he just loved running. He's paying for it now.

I've had a saddle failure that left me standing for 15 miles. The trick is to remember that you aren't sprinting, you aren't trying to ride hard or fast, you're just riding while standing up. Done at moderate intensity it's not that bad.

But it does feel quite unnatural if you're used to standing==sprinting or climbing.

I suspect it's similar to the billions of utility riders around the world who routinely ride their one-speeds at a cadence the experts say will wreck your knees. Sure it will, if you're riding hard at that cadence. But if you're just idling along at about the same effort level as walking, it's not a problem.

Perhaps it's time for an Elliptigo?

Over use injuries can happen in any sport or vigorous physical activity; running, cycling, swimming, XC skiing, basketball, soccer, and hockey all contain the potential for injury. Luckily, our bodies have a system for telling us when we are hurt, and when we need to back off for a while. Listen to your body, and it will heal. Young guys think that they are invincible, so they run or play through the pain. Plus, there is a stigma of shame and weakness around admitting that you're injured, especially when you're an adolescent male. I know, I used to be one (adolescent, that is, I'm still male :D). It can be worse if you're involved in an organized sport, where there is pressure to perform.

It sounds like your co-worker was brought low by youthful over-exuberance, which manifested in his running habit. I know guys with the same complaints about hockey and soccer, that they're now wrecked because of overdoing it back in the day. And that's just a problem inherent in being young, strong willed, and inexperienced. Teens don't understand (unless there is a coach there to tell them, who they might just ignore anyway) the long-term consequences of performing while injured, that running through the pain of shin splints is a bad thing that'll come back to haunt and hurt for possibly the rest of your life. Most of us survive youth with minimal damage, some of us become crippled for life, and some of us don't survive it at all.

For the vast majority of us, running is very good for you. Like any other regular aerobic exercise, it will literally add years onto your life and provide a significant resistance to diabetes and cardiovascular disease. It improves self-esteem by provided barriers to overcome and goals to meet. You might get hurt sometimes (hey, welcome to life), but as long as you're not stupid about it, chances are great that you'll recover and come back stronger and wiser than before.

All that said, there are an unlucky few who're physiologically ill-equipped to run, with hereditary joint and back problems. We as a species have been removed from the forces of natural selection for a long time, and this is the price that some of us pay. My bad eyes might've spelled my doom, were I a hunter 10,000 years ago. Today I wear glasses, and even without them I can successfully navigate a grocery store, bring home the bacon, and spread my weakened genes. So running isn't for everyone, but for the vast majority of us, it's what we were born to do.

:lol:

.....nothing is gonna happen to you if you stand and pedal, except maybe calves stronger than they would have been otherwise. If you are fatigued enough you will sit for a spell, otherwise you have a superb suspension system at your disposal and no undue pressure on your prostate with is a good thing. Absolutely nothing wrong with what you are doing, you are riding the way we have walked since Adam took off his knee pads so any damage to incorrect biomechanical usage of your joints and ligaments are hardly something to be concerned about, but like was said, overexertion/over use of any body part could plainly lead to issues but the act of standing while pedaling is hardly such an act. Like the yorkshire man said..."that nowt as queer as folk"..you'll be just fine..ride on and enjoy.
