Tips on pacing?

Hi im 16 right now and a junior at my high school. My sprint time in my 100 free is 59:00, but when i swim during practise, i can barely hold 100s on a 1:20. Can you give me any tips on improving my pace? Also... sometimes when i swim probably more than 50-75 yards, my shoulders kill with pain, and i just lose all momentum, and can't start again. Is this a problem with my pacing? or am i doing my freestyle wrong? Any tips would be greatly appreciated. ~Swim4life13 I do not think that having shoulders that "kill with pain" is something you should be experiencing. A lot of swimmers get shoulder injuries, and in my experience that seemed especially true among young women ages 13-16 or so. (Not sure if you are a male or a female.) You need to get that checked by a sports medicine doctor... As Paul says, the pain might be related to bad technique, so you should get that checked too...
