Long swim today but not nearly long enough. 70 complete laps in 1:14:10. Projecting this out, I'm looking at a time of basically a 1:30:00 time on race day. However, given the waves, hoards of people, lack of walls, I'm looking at a time much higher than 1:30:00.

I'm not sure what my swimming strategy should be. In the pool, I think I can march down each full lap consistently in a minute, but I'm not sure whether I should be trying to really push it in the beginning and then fall off in the middle to store energy for the final push.

Today, I sprinted in the beginning, ran out of breath by 0.5 miles and then fell off until I hit about 1.5miles, at which point I regained my normal pace of one full lap per minute. I felt totally winded at the outset, but maybe this is not a good approach. Thoughts?
