View Full Version : Predict my time?

Hi all,

I'm wondering if anyone is aware of any online calculators you can use to predict your time in an event. For example, "I swam 100m free in 1:28, what would I be able to swim the 800m free in?"

I know this wouldn't be an absolute predictor, just something to give myself an idea of where I would be in the various events, without having to go out and swim them all in competition. :-)

Many thanks,
Canuck

I don't know how helpful this will be for you, but here are my times from two years ago when I swam all the freestyle distances except the 1500 m. This was at Colony Zones LCM championships:

50-- 27.9
100-- 1:01.63
200-- 2:19.39
400-- 5:03.27
800-- 10:41.99

double 50 and add 3 sec = 100
double 100 and add 16 sec = 200
double 200 and add 21 sec = 400
double 400 and add 34 sec = 800

so...my prediction for you....

double 1:28 and add 20 seconds = 3:14 for your 200 (adding more time because your base is slower than mine)

double 3:14 and add 30 seconds = 6:58 for your 400

double 6:58 and add 40 seconds = 14:36.

This is just ball parking it. If you are a distance swimmer by nature, and the difference between an all out sprint 100 and a moderate 100 is not that big a time increase, you will probably do better than a 14:36.

If, however, you aren't in pretty good shape, you may find that a 14:36 is hard to achieve.

Let us know how you do!

I am willing to bet, however, that my 14:36 prediction is going to be a lot closer to you race time than Sr. Stillwater's 12 minutes.

By the way, Stillwater: did you chose your name because of the chestnut about waters running deep, or because there is a prison outside the Twin Cities known as Stillwater?

yes, but the contestant who guesses closer to to the actual time "without going over" walks away with the his and hers samsonite luggage package.

What are your 50M and 200M times?

While I have spent time in the Twin Cities, the chains I had upon me were of my own making, not the law.

This month I am vacillating between cheap booze and an "Almost Famous" band.

Next month will be different.

Thanks to everyone for their replies! The 1:28 was just for an example, my most recent 100m time is 1:38 and 50m is 41 seconds (haha, I know, I'm slow!) Never swam competitively as a kid but am loving masters swimming and just trying to improve for my own sake!

My best 200m was 3:49 but that was about a year ago.

There are running calculators online where you can input your time for a distance (ie 20 minutes for 5km) and it will tell you what is roughly an "equivalent" time for 10km, half marathon, mile, etc. Seems like the same thing might not exist in swimming?

But the suggestion by Jim Thorton to double the time and add 20/30/40 seconds is exactly the kind of thing I was thinking - sort of a rule of thumb to get an idea of where you'd be at. Alternatively, I was thinking I could work backwards with it - ie I want to break 15 minutes for 800m, what kind of 100m times do I need to be able to get?

Many thanks for any and all suggestions! :-)

use this:

http://www.vaswim.org/cgi-bin/rcalc.cgi

And enter your specific info for the 100 to get a rating. Then take that rating and use it to estimate a time for any pool event you want. But it's only an estimate.

If I used my 50 free to generate a base rating, then there is significant drift as I select longer events. My 50 rating generates a time .8 sec faster than my best for 100, 6 seconds faster than my best for 200, etc..

This is a good suggestion. But just so you know, the drift isn't always in one direction for everyone. For instance, I tend to do better the longer the race.

So if I start with my 100 time, for instance, I get a 200 time that's 5 seconds slower than my best, a 500 time that's 20 seconds slower than my best, etc.

Using the calculator I get 77.2, 74.3, and 67.5 resp for the 50, 100, and 200 SCY.

I can assume that if I did a 500 my rating would be 67.5 or lower.

It depends, each swimmer is different,
there are no hard and fast formula's
We need to see how more of your times compare:

Swim the following fast for time:
50
100
200
500

give us those & we can make fairly accurate guesses

It all depends on:
+ What you are, (sprinter, middle distance, or distance)
+ How you've trained in the past,
+ How you've been training recently
+ How you split your races

So we need more data, all we have is one point of reference


if you look at one swimmers 50 paces for the following swims
50 fr
100 fr
200 fr
500 fr 400 fr
1000 fr 800 fr
1650 fr 1500 fr
3000 fr
5000 fr
10,000 fr

each swimmer's times plots a line

Nope, not a bit. Just pointing out that YMMV.

But if I use the rating from my 200 as my base, then my 100 and 50 are phenomenal in comparison.

By golly, you're right.

Just to make you feel good about yourself: you should do a 200 fly, and then apply the resulting rating to your 50 fly. :bolt:

Hmm, I think you might need to modify the time entry field and add the next larger unit of time, just to be safe, add the next two please.

My daughter looked me in the eye after doing the 200 Fly for the 2nd time this Sunday and said 'so, when are YOU swimming the 200 Fly, Dad?'

I'm not sure I'm ever going to and if I somehow have a complete lapse of sanity, I'm not sure I'd be able to beat her 3:22.

This is great info - the LMSC of Virginia Rating Calculator is exactly the kind of thing I've been searching for - thank you!

I find that my times give me a lower rating the longer the distance. I do have a recent long course 400m time of 8:22 to go with the others. I go from a 63.0 for 50m, 59.2 for 100m, and 55.3 for 200m. My 400m LC is actually 52.6!

I've been training for 3 years with masters swimming, initally about 3 practices a week, now 4 per week of 2000-3000m/practice. I've always enjoyed longer distance swimming much more than the sprints, but my sprint ratings seem to indicate I am actually better in the shorter events. Aside from my first swim meet (too excited!), my splits have generally been pretty even (can't remember them offhand though).

Maybe I need to keep working on my endurance more to bring my longer distance ratings up? :)

Great Bay Masters has a similar rating calculator here:
http://www.egswim.com/gbm/RatingTime.php

As mentioned in several other posts, there is no guarantee that you will be able to achieve the same rating in a long event as in a shorter one. In my case, my 200 rating is much better than my 100 or 50.

... the drift isn't always in one direction for everyone. For instance, I tend to do better the longer the race.

To add to the fun, apparently it is possible to peak at a certain distance, and decline at both shorter and longer distances.

Attachment: Rating-Distance.jpg (http://forums.usms.org/attachment.php?attachmentid=1955&stc=1&d=1269955437)

Since last October, I've managed to swim my own abbreviated version of the check-off challenge -- all the freestyle, backstroke, and IM events -- at least once each, in competition. The attached graph, plotting VA calculator ratings vs. distance, shows a clear peak at 200 yards, regardless of stroke.

Any good coach who knows you and how you swim should be able to help predict times for you.

Back in 2000, after a workout, I asked Ron Johnson for help with seed times for an upcoming meet. He told me to do a 50 off the block. From that, he gave me times for 100, 200, 500, and 1000 free. He was nearly right on across the board, I think off by 2-3 sec for the 1000.
