I'm not real sure how far I could swim if I just kept going. I can swim past 2000 yards comfortably but time constraints keep me from doing so... it's always before work and if I spend too much time in the pool I'll be late for work! So, I suppose I just want to work on speed. I don't have an official coach, but considering what a poor swimmer I was at the start and how well the pool lady has coached me so far, I'd say it's been a success!
