How many of you are afraid of....

I fly down the hills with no brakes,  but I always, always, always clamp my knees around the top bar.  It makes my bike feel more stable and not wobble as much.

Also, you might try lifting your bottom off of your seat and allowing your legs to absorb the road bumps (like shock-absorbers).  It will make you bounce around a lot less so you can feel more in-control.

I have the same natural inclination.  Downhill makes me nervous.  I find that it does get better the more I do it.  Just keep riding and you'll gain comfort in your ability to descend.  You may have to re-learn it each season, but such as it it.  

Um, hi. Me. Seriously, I should be the BT mascot of hating downhills, I am so freakin scared of them. I've basically ended up hating cycling because of it. Sadly, I don't have any suggestions for you as all the suggestions everyone else will give you don't work for me (ie, doing downhill repeats - it actually makes me MORE scared). But just so you know, you're not crazy in your fear. There are lots of people who don't like them. And unlike me, most of them can still ride hills. If you can actually do them, that's one step ahead.

I agree with the earlier poster about putting your knees against the top tube.  I also try to focus on staying relaxed, and not gripping the bars too tightly.

That's not fearless, it's just stupid.  If you are going to have to stop, you can't fly down the hill in a high gear.  You must downshift and slow down. 

However, just practice on a route YOU KNOW where you know you are safe to go down the hill without stopping or where there will be an uphill to slow you at the bottom.  And, take your bottom off of the seat so you can "bounce" with the bike and clamp your knees around the top tube for stability.

And, if you are type "A" keep track of top speed like the poster above mentioned and try to do 1 mph better every time.
