If you want to be faster, maybe work on your leg strength and build the strength-to-weight ratio. I, on the other hand, need to work on the weight end of the ratio, I have plenty of strength. I weigh WAY more than 109lbs and I'm only an inch taller. I've been working with my doctor and she wants me to shoot for 25 more pounds but no more than that--and that would still be more than 110 lbs.

Oh, and I SAG'd for my husband this weekend in a tri and was shocked that a woman who was my size kicked his butt! I didn't think larger woman could run fast--but she ran 7 minute miles in a rather lengthy tri. She's my new hero. DH is sooo sick of hearing about getting beat by a girl, but she rocked. I want her autograph.
