Alright! I surrender! I need help!

Swimming one time a week is cutting it and I need help to improve with my swim. I am looking for an early morning (5:30am or something close to that) weekday swim group in Philadelphia. I would prefer an instructor that knows what they are talking about when it comes to triathlon specific swimming...but that isn't required.

I do want to note that I am in the City of Philadelphia...a 45 min commute out to the burbs will not do.
