What was your time limit on the 800? 800m, 17 minutes and going slow don't math right.Frog kick only. Don't try to go fast.
I did my 800m and 400m divimaster swim the same say and was the only one not worn out.
I am lazy and out of shape. The person that did better than me swam regularly.
And you are talking kicking only, correct? No arms?
