I had gotten to the point where I was riding places like Flatwoods, and Santos yellow and blue, and most of Alafia, and Boyette in the big ring. That is until this injury I am nursing.
I found that I was able to moderate my heart rate and therefore my stamina by getting to the point where my legs were strong enough to use the big ring primarily. I used to use the middle and small ring all of the time, I was spinning myself silly. This was making me tired and fall behind my friends. This stuff is no fun when all you are doing is trying to catch up.
While riding technical sections I would use the middle and little ring and frankly, shift constantly.
The whoops on bridges, in my opinion are best ridden in one gear. Pick one that gives you plenty of torque for climbing but is not to easy. For me that is the middle ring and two or three in the back. Those whoops are the best when you are barely pedaling. Get some speed up after you complete the climb up to them. That first one is the best if you just roll up the hill, after a fast descent. If you can hit that one right you will come out at the end just smiling from ear to ear.
That section rocks! It just happens to be the last trail that I rode just before the fateful Rabbit Ears attack. Bob will vouch for it! we were flying through it!
Oh God I miss the dirt!!!!!
