5x matters way more than 30k. I make the same rate of improvement on 5x3k as I do on 5x5k until I plateau. After that, I have to add volume.
I thought everyone knew that 3x won’t get you very far.
Get wet, swim hard, rinse&repeat, alot.
Everyone knows you have to swim more period, but do you think most triathletes realistically swim 5x.per week 3k each session while doing bike run in a race build? Do you even do that?
Consistency and volume are critical but the far.more relevant and useful question is how you fit that into a plan of swim bike run year round consistently.
I had the opportunity to give this a lot of thought as I have done really low volume biking for a number of years and high volume swimming. Its easy enough to do high volume swimming if you cut out a pile of biking. If you swim all 4 strokes the conditioning of the legs is amazing. I am actually biking at higher wattages now as I enter 55-59 in few weeks than when I was racing 40-44. I concluded that I wasted a good part of the last 20 years on the trainer and biking instead of in the pool.
The bike hours hardly translate at all into a faster swim, but the high volume high intensity swims sessions translate very quickly to great bike TT legs. I did my first season of tris this past summer and this year my bike mileage was HALF of what I did when I was a triathlete. But my bike splits were no different and my wattages on the trainer are higher than they used to be. I did 5000km less biking (so let’s call it 170 hours less biking, but I did 800km more swimming, so call that 270 hrs more). In any case, my times to T2 were very similar to the past by cutting out a pile of biking and moving more time to swim. I AM swimming all 4 strokes and doing a lot of leg sets though. I think for a good transfer to the bike, all that back stroke, breast and fly and associated leg sets for them really help me…if you do triathlete training and have the pull buoy in there 90% of the time to simulate wetsuit, well that type of swim training likely won’t transfer that well to the bike since you are not using your legs.
I used to be in this camp thinking incremental swim time was a waste of time and was taking away from the bike, but I am sold that most of that time on the bike is a waste of time for half IM and Olympic tri. Most of the performance for these distances can be gained on the bike with shorter harder intervals sessions. 90 min on the trainer is excellent for a half IM or Olympic tri (provided that overall volume is high enough).
So whether I do 8 hours swim, 4 hours bike and 4 hours run or 3 hours swim, 9 hrs bike, 4 hrs run its all the same total hours, and the question is which breakdown do I get more performance out of. I am leaning towards the high swim option.
I have a half IM coming up in 8 weeks in Dubai. I am going to experiment with the 7 hours swim, 3-4 hrs trainer, 4-5 hrs run plan and can report back.
