t say just because he is at a 4:40 mile fitness level that he could complete a 400M freestyle in under 4:30. Without ant swimming benchmarks it is kind of hard to answer his question. What were the times
for each of the 300 swims? Have you tried doing a 400M swim as a practice to see how long it takes to complete it?
Granted I found an appreciation for the 400M in my masters years that I did not have as an age grouper or college swimmer, but Iâ€m a 1:49/4:49/10:02 200/500/1000 yard swimmer and never went under 4:30 in a 400. Thatâ€s why I showed a level of skepticism.
anyways, like I said, without some swimming results (even just practice times) to compare, your question is difficult to answer. If you finished your 300 swims in 5-7 minutes, then yes you can definitely get that last 100 meters done in time. If itâ€s taking you more than 8 minutes to do a 300 though, getting 400 under 10:00 may be a tall order without more swimming training.
