How much distance can you swim in 1 hour?

I have no idea. This is now on my list of "things to do over Christmas vacation." I'll report back after Jan 3.

I'll let you know after Jan. 8, last year was 4875.

Last year, I did 4920 yards in the 1 hour postal. I hope to break 5K this year. Depending on the practice, I can get 3,000 to 4000 done in a hour.

2 miles (3300 yds) pretty comfortably , maybe even with a short rest in there.

Just check out the Postal One Hour swim results from this year.Starting 1/1/10 you can do the 2010 1 hr swim.

Hello, Mr., Mrs., Miss, or Ms. DDL, Your question is an interesting one and timely. I went to the Y today with the intention of swimming an easy hour swim to kind of get myself into the mindset for a higher intensity "official" hour swim in mid-January. Usually, I will warm up before practice, maybe even do the first 500 yards with open turns just to let my back unkink. But today I just started swimming with flip turns, trying to stay smooth and not at all come close to the lactate threshold, but not stop either--just a long smooth cruise. Given the kind of shape I am in right now, I doubt I could have swum at any speed for an hour without getting a little tired. But the object was just as you asked--how long can you go in an hour without really pushing it. The answer, for me, today, was 4400 yards. I'm 57. By contrast, these are the 1-hour swims I have done in the past when I pushed it and wore a body suit: age 51: 4996 yards age 55: 4825 yards age 56: 4700 yards My all time best 1 hour, I held about a 1:12 pace per 100. Today's more lacksadaisacal effort, I held about a 1:21 pace. Mr. Q, a couple years back, I did 100 on 1:20 for the whole practice, and did indeed finish a 4500 yards. You might try doing an actual nonstop hour swim. It's different than you might imagine, and extrapolating from "it's easy to hold 100s on 1:20" to doing this for an uninterrupted hour might prove different than you think. Maybe you will pick up the speed; maybe you will hold it steady; and maybe you will tire out. But it's a different experience than you think it will be if you've never done it.

I could swim about 2800-3000m in a 1hr swim

4500 meters

ddl, I can hold 1:20s comfortably for long periods of time, so all freestyle for an hour, I would be able to do 4500 yards. But a normal workout, with kick, drill and stroke, I am completing about 3200 yards in about 50 minutes. That is a 1:33+ average pace, but my freestyle will be 1:20s or faster, my kick at 2:00, my stroke at 1:40, etc. What is your objective? Maybe people can give you better information if we know what you want to learn from it.

Have the 1-hour postal authorities said anything yet about whether wearing one is kosher? Yes. The rules as of Jan 1 apply, so tech suits are OK.
