Swimming venues:

a) If you have big-name gyms around you, check the gym's web pages; sometimes you can print a (free) 1 day pass to come in and try them out. My gym has been known to negotiate with folks if they're willing to commit to a longer contract.

b) Our city park's pool is open for adults only for $1 per person from 6 to 7pm, weather permitting. It's an outdoor pool and not heated and therefore seasonal, but it is Olympic length and can't beat the price.

c) Check your local high schools for public swim times.


Last bit of advice -- don't wait until your swimming is "perfect" before you sign up for your first tri. Just seat some reasonable goals and go have fun.
