View Full Version : 1650: pacing question

March 14th, 2013, 07:06 PM
I just blogged this workout (http://forums.usms.org/entry.php?27670-1650-pacing), but wanted to post my question here on the forum. I'm pretty excited because i just finished a set of 20 x 100 on 1:40 and all my reps came in around 1:29-1:31; the last two were in 1:28 and 1:27 because I had so much gas left in the tank. My total yardage was 4400 today (1200 warm-up, drills; 1200 drills, cool-down). 1:40 used to be my BASE, but I haven't done a test set in a long time. The last time I did a broken 1650 was more than a month ago now and the total swim time was a tired 25:51; based on today's workout I would guess it would be a lot faster now.

Can I expect my new 1650 pace to be 1:29-1:31?

I have to turn in a seed time for the WI SCY State meet coming up in a week and a half and I'm wondering if I should go with mid 25-minute range or whether I should send in my 1500-m time from December (26:53). Some of you know I've only been swimming seriously for a couple of years now and only been swimming meets for about four months, so this will be my first 1650 in a meet context. My training lately has included a lot more speed work, and work on the different strokes (I'm trying to complete the check-off)... I really like the 400 IM for example, but hadn't swum fly before this year. My training the last couple of months has really focused on improving the 100-200 times in back and the 200 and 400 IM. So, I was surprised when I came back to do some pacing work for the 1650 that my freestyle seems to have gotten a little faster and a lot easier.

I would say yes and I'd give them the faster seed time. 20 x 100 is always a very good indicator for me.
As you were getting 10-11 seconds rest, you might try the set on 1:35 next time. Threshold sets should give you :05-:10 rest per 100, so that would get you a slightly better threshold workout (I think you can probably make that interval). :D

I would go with the mid 25 as your entry time.

I used to do a set where I'd swim 100s on the 1:30 and try to hold my 1650 pace. My goal was around 1:02-1:03, so I was getting more rest than you did. I hit my goal pace when I swam the 1650 tapered. Based on this you should definitely be able to hold a 1:30 pace in a race, I would suspect.

I just did some quick calculations. A 1:30 pace brings my 1650 in at 24:45 and 1:32 at 25:20. I'll probably go with the conservative time for my seed, but I'm really going to try to break 25... I didn't know I was that close, since I was on a plateau for about a year (~29:00 for the mile). Hope to keep the momentum going through the summer! Thanks for the feedback!

Split the diff. and go 25 flat. Maybe you can hang with another 25 & improve. Good luck!

Here's a set my masters coach says will approximate your race 1650 time. I have zero empirical evidence that it works for me, b/c I don't swim 1650s voluntarily! But I know others who seem to think it works.
Swim the following 1650 hard broken as follows and subtract 1:40:
11 lengths, rest :15
10, rest :15
9, rest :15
8, rest :10
7, rest :10
6, rest :10
5, rest :10
4, rest :05
3, rest :05
2, rest :05

Kirk's comment on the meet report I wrote up for my blog reminded me I should report back on this thread... I listed 25:20 as my seed time and went 25:05 in the 1650 at state, about a 1:31/100 pace (faster pace than the 500 I swam 2.5 months ago in my first meet of the year)... even after dropping 10 seconds off my 400 IM PR and 8 secs off my 100 BK PR.

Pretty much right in line with what you guys were predicting. Thanks!

Great swim! Congrats!

Great swim! Definitely see < 25:00 in your near future. What did your splits look like?

They just posted official splits and times last night, so I cut/paste into my blog here: http://forums.usms.org/entry.php?27853-1650-official-splits

I started off with :37 off the blocks and settled in right at :45-:46 per 50 the whole time; managed sub :45 pace per 50 in my last 150 yards. Both the 500 and 1000 splits were PRs for me as well.

I am a bit late with the congrats, but nice swim!
