+1 with those questioning about needing to lose another 3-5 punds.

I wish I knew the link where I read about psyche of female athletes and male athletes. It had to do with marathons mostly.

The study said that we tend to concentrate on our need to be lighter to perform better. Almost all female marathoners are anorexic. Few have died. Male however concentrate on building strength with little emphasis on reducing weight.

To perform at your peak, your body weight has to be within some range. Seems common sense to me. if you are too light like Karen Carpenter, who died of anorexia induce heart failure, that's not good. Then again if you went to the other extreme, at 400 pounds that's no good either. Again common sense.

At your weight, you probably can see your ribs. That's not good. And what about your period. If you stop because you are underweight, your body is telling you something. I was a mid-distance (10k runner) in my 20's and I weighed in at 105 pound. and I'm 5'4". I also biked alot back then too. I didn't have the muscle mass to sprint, and I didn't have the needed endurance to run or bike long distances because my body fat was way way too low. You stop menstrating and all sorts health issues starts up.

When I popped my weight back up to abou 110-115 pound, I felt much stronger. And my time actually improved. So you don't need to lose anymore weight.

Instead concentrate on your strength, endurance and tolerance to heat. These things can be improved upon.

You are already below optimum weight for endurance sport.
