I have never swam in an open water event. I started swimming again in january in a 25 meter pool. I can comfortable swim 1500 meters in 24 minutes (no flip turns). Realizing open water has tides/currents etc. I am attempting to calculate what I might be able to swim a mile in open water. Any thoughts? Also, how many meters should I be training on a weekly basis to swim 4.4 miles. I am 46. Thanks..

Other than favorable currents, most of the open water impacts have been negative on time as compared to lap swimming ...
agree - if those impacts cancel each other out between start and finish You may still be slower by 10% compared to lap swimming, I would guess.
Wouldn't the buoyancy of salt water (assuming ocean/bay, not freshwater lake) be a positive factor? ...
Definitely! As an avid freediver I could write stories about bouyancy. Salt water has a specific weight of 1,03 on the average. According to the Archimedes principle an immersed body is 30g (approx. 1 ounce) lighter for each liter of water it displaces. We are talking about 2 Kilos (4 lbs) less weight in salt water with average salinity. Besides: the surface of the ocean seems to be more penetrable compared to a lake surface. May be, because of it's unique undulation.
Quoting jdut: ... I have read (maybe in Penny Dean's book?) that salt water feels about 5 degrees warmer at the same temperature reading ...
Is anybody supporting this theory? I would be grateful for Your answers
cheers
