Triathalon dry run!!

Just got back from the mini triathalon (tri for fun) in pleasanton. The winner finish time was 58:15. Mitch and I think our biggest issue is the Swim. I am frankly scared of the swim and unless I can do 10 laps at the pool without a break, I dont think I can do this. I need to really increase the rate of training to possibly 4 times a week.
