Good 1500 Swim Time (Page 3)

just curious to how you would say a lake swim is always faster to an ocean swim. Also to referencing a race you didn't do?

Lake vs. ocean: I've swum in both. I can also look at results from races held in oceans and held in lakes. There are probably circumstances where the ocean could be faster, but the typical route - three sides of a rectangle - means you have to swim against the tide and with the tide equal distances. That slows down average speed.
I haven't swum Olympic tris, but I'm not sure that matters - no more than the fact that I'm not a beginner swimmer. The question asked was what's a good time for a beginner at 1500 meters - not how fast am I or how fast was I in my latest race.
So I picked out one at random that gave splits. The results it gave passed the sniff test, I thought.
It would be better to sample a bunch of races, which would even out the quality of athletes and the mismeasurements of the 1500 meters, vagaries of weather, etc. If someone has the time to do that, I'd be interested in the results.
