The IM Lane

I've a question for the experienced 400 IMers. In prearing for the 200 bk (and and very recently also the 200 br) I have found that swimming sets of 4x50 with about 8-10s between the 50s is a valuable training tool. It allows me to practice at or near race pace, yet the rest is sufficiently brief that it "feels like" a full 200, as opposed to swimming shorter distances on longer intervals. I also find that the add-up time for a strong effort on (4x50 with 8-10s rest) is a pretty good indicator of what I can expect for a full 200 in a race. I'm looking for a similar training tool for the 400 IM. For 4x100 IMO with N seconds rest between 100s, what value of N gives an add-up close to race time? Is this even a reasonable approach? It removes all of the change-stroke turns. Would it would be better to break at 50, 150 and 350? That seems cumbersome.You're trying to get in the range of your actual 200 back time (minus rest) with that set, and are attempting to design the same kind of set for the 400IM? I'm not an IM'er, but if this is so and you want to keep the transitions, maybe reps of 400IMs- break at the 50, and every 100 after that for 5-10sec? That would be of the same design as your 200 back set.

Lots of 100s, 150s, 200s, etc. repeats on minimal rest just to build your cardio. The 400 IM can be very taxing on a person in the race, even someone who is a great IMer. I don't know how the broken 100s IMOrder would add up as a comparison to a race pace 400 IM. I pretty much train free and fly, and just attack the 400 IM when the time comes. :D

I addition to IM work, begin training for middle distance events like the 500. Lots of 100s, 150s, 200s, etc. repeats on minimal rest just to build your cardio. Check. Such sets have been the meat and potatoes of my training for years. What I am looking for is a way to get the "feel" of race pace. I've found this to be really helpful for the stroke 200s. I need to know what the right stroke rate feels like that will produce my best time. I need to know just how much pain I can expect to experience at each stage of the race and still not get hit by a falling piano. This brings up a question about pacing. I often see in these forums the advise to "loaf the fly" in the 400 IM. (I think ande can be credited with this suggestion. ande maybe you can comment?) I've done quite a few timed 400 IMs in practice over the past several months and it was a surprisise to me that taking out the fly quite hard produces the best overall time, so now I wonder what "loaf" means. Maybe I just answered my own question... maybe ande's "loafing" is my "quite hard"... no, correct that, ande's loafing is my "blazing freaking fastest hardest I ever dreamed of swimming":)

I think I'd work out the rest time by doing the 400 IM broken by 50s first.I'd figure what I want my split for each 50 to be and then allow enough rest to achieve them.Then keep reducing the rest until you get to 15 sec between 50s and then I think you are good to go.

I often see in these forums the advise to "loaf the fly" in the 400 IM Yes, good advice, but advice that I don't follow very well at all. :) My fly is my core of the IM, and I have to take full advantage of it. Even if I back off a little, my backstroke still sucks, and my breaststroke is decent enough after the backstroke recovery. So I just 90-100% my fly in all IMs. Not the advice for most swimmers out there, but works for me.

BR is my down fall, you must be born with a good kick!

I have to side with James on this one......the 100IM is all out anyway, the 200 is all out on fly and hang in there for the rest, but the 400 has yet to be raced. I'm working on the principle of needing to improve my back & *** so they don't totally fall apart having just swum a hard 100 fly. However, Karl - you're a backstroker right? So I would think that even after going out hard on fly, you'd manage a decent backstroke leg and maybe even recover a little in time for the ***? I have heard that the back and *** should be swum at 200 pace, but not being a back/breaststroker I have no idea what that is!

I also swim 400 IM and I like to swim broken IM's but I will break at the 50 in the fly then at the 100's thereafter, in order to practice the transition turns. Also that way I can swim decent fly for the entire 100. That seems to work best for me, take 10 seconds on the break. How does you add-up time for one of these broken 400 IMs compare to your race time?

However, Karl - you're a backstroker right? So I would think that even after going out hard on fly, you'd manage a decent backstroke leg and maybe even recover a little in time for the ***? Gulity as charged. I think you may be onto something though. Maybe I can push the fly a little harder because i can take the edge of the backstroke and not loose as much time as someone for whom backstroke is their weakest stroke. In other words, an easy fly costs more time than a recovery backstroke for me... maybe.

.. I'll try my best to sprint the fly...Thanks for the heads up on your strategy for next weekend:). I like the comment from the Israeli Olympian this month in Swimmer about 'sleeping' the 1st 100 of a 200 fly. I like to think about sleeping the fly on the 400 IM as much as possible. No use getting all tuckered out on the hardest leg with three strokes still to swim.
