NEW TO THIS!!! i have to swim 300m?

Question

How would it be better to train for a good time in 300m?

By doing 30 laps in a 10m swimming pool

or

Go out to sea and swim straight out 300m off shore???

which one would give you a better time and better stamina?

Answer 1

the second choice is better, since you wont keep getting stopped at walls but for both choices, swim more than a 300m. train your body to do a 400m just so you know you can complete it

Answer 2

Swim the 300m every day and each day try to beat your time by 10sec. This is how i train and i works for me. Good Luck hope you win. :)

Answer 3

straight out to sea. but i don't know how your going to measure it. it depends. are you doing the 300m in a trialthalon?

or a swimming race?

if its a race. i think you getting mixed up with the 400m.

if its a race, go to a 50m pool and do six 50s on a hard sendoff.
