    little math correction, your CSS its not a 1 minute and 12 seconds, its a 1.12 minutes which equates to 1 minute and 7 seconds. other than that, great video. keep up the good work.

    • @nicolajc
      @nicolajc 4 роки тому +1

      So after 400meters that is 4minutes and 28seconds - but that is faster than his 400meter timetrail qualifying the CSS ??

    • @marsert123
      @marsert123 4 роки тому +2

      @@nicolajc yes, because the css pace contains the 200m time aswell. building the average leads to this effect

      Thank you cos I've been trying to reverse engineer this and I can't see how he's got 1min 12 secs? I keep getting 67secs too......I'm a bit baffled

    • @kareemdayes6703
      @kareemdayes6703 3 роки тому +1

      Ok so i figured out what's wrong here. His Minutes : Secs time don't match with his seconds conversion. If we go with the first Minutes : Secs time then 1:12 is the CSS, if we go with the seconds he quotes second then 1:07 is his CSS. He's used two different sets of time at two points in the video. But the point is I've figured out how to convert my m/s into s/100m. Confusion solved. This is a really useful exercise! Thank you. Will be doing this bi-monthly from now on I think to track my progress. Really useful tool and great explanation.

    • @kareemdayes6703
      @kareemdayes6703 3 роки тому +1

      If we go by the time in seconds (2nd time he quotes) then he swam the 400m in 4:21 and the 200m in 2:07 ;)

    I've been disappointed with GTN content recently, but this was really useful and hopefully by implementing it I can finally see my swim times go down. I'd love to see a video about using a Tempo Trainer to help pace in training.

  • @alanjackman5729
    @alanjackman5729 6 років тому +2

    Another good test we did in college was a T-30 but done differently you would do 200 threshold (going off heart rate) with 30 seconds rest doing that for 30 minutes then you average out your times and boom thats your threshold pace too. It is a 30 minute swim...but I felt it got a good accurate reading.

    • @markthrelfall3577
      @markthrelfall3577 6 років тому +2

      Alan Jackman you’re very right. A T-30 is another good option. I’ve not heard of it broken before, but that’s maybe one to explore

  • @stug45
    @stug45 6 років тому +3

    Great explanation....for my athletes it just needs the tempo trainer and how it helps to pace!
    For me as an ex swimmer, these sets are the ones that get me from sitting on poolside with a fast 100m but terrible pacing, to the fastest swim of the day in 6 weeks. I'm now back training full time and I'm getting myself ready for some important races!

    • @juliaburmeister2038
      @juliaburmeister2038 6 років тому +5

      I'm a competitive swimmer focusing on the middle and longer distances and also butterfly but find it useful to practice the other strokes as well. E.g. Backstroke and Butterfly use simmilar muscle groups and therefore train those as well. It also helps with keeping that range of motion in the joints since it is never good to train something only in one way. Variety in training is as important as consistency but keep in mind that you need to have at least decent technique for it to work. But it defenitely helps with keeping these boring swim sessions a bit more exciting

    • @alanjackman5729
      @alanjackman5729 6 років тому

      I second this as well. I was a butterflier in college so I love me some butterfly but I do find that when I get aerobically fit in butterfly it helps my freestyle too.

    • @maikholzhey6167
      @maikholzhey6167 6 років тому +1

      Alan Jackman You get aerobically fit in butterfly? Please post your actual heart rate after 1500m butterfly^^ - This is what I think is exactly the problem with swim training, you're not training purely aerobically with a decently low heart rate to build endurance and you're also not doing speed work or strength training either. You sit a very difficult point in your zones. For me it is all about technique and efficiency to get less fatigued out of the water and fresh on the bike. Triathlons are not decided in swimming...

    If I am taking a lot longer to swim 200m (about four minutes), would I be better taking a test over a shorter distance, such as 200 + 100, or 150 + 300? Could you also give some guidance on determine my pace for aerobic swimming? I often set off too fast (for my level) and then die once I get up to 300 or 400m.

    • @markthrelfall3577
      @markthrelfall3577 6 років тому +1

  • @aaronroeck1
    @aaronroeck1 6 років тому +1

    How do you use css for those sets? Swim all of those interval examples at css? Also when pacing a race how do you know what percentage of css to go at? Obviously I know shorter than 1500 you can go >css but on longer ones, how much less that css should you go?

    • @markthrelfall3577
      @markthrelfall3577 6 років тому +1

      Aaron Roeck for those sets explained in the video, you should swim at your CSS pace. Just take the relevant recovery.
      In terms of longer swims over 1500m it depends really. Half Ironman/middle distance - there shouldn’t be much drop off. Very minute. It’s only an extra 400m.
      I’ve just done a little math on my own times to gauge any difference for an Ironman swim - I reckon it’s around 2-3s/100 slower. But could differ a little depending on ability. I will investigate this further for you

  • @Wilsonwill89
    @Wilsonwill89 6 років тому +1

    Couple of questions... does it matter if done in a 25m or 50m pool? One problem I've found with Training Peaks with swimming is I've done my CSS test in the pool and TSS scores are appropriate but then when I do an open water session where I'm much faster my scores (TSS, ATL, CTL) are way higher, what can I do about this?

    • @markthrelfall3577
      @markthrelfall3577 6 років тому +2

      Will Wilson it doesn’t really matter. Times tend to be faster in 25m, particularly if you do tumble turns. I’d try and do it in the distance pool you will be doing the sets in regularly. For me, I would normally swim 50m. If I ever swam a CSS set in 25m, then I would just take roughly 1-2 seconds off per 100m.
      With regards to scores in TP, that isn’t something I’ve ever thought about, but you’re right. If you’re wearing a wetsuit, you’re going to swim faster. I guess you can just manually tweak the results. I’ll have a look into this - great question

  • @jonathanhacker6913
    @jonathanhacker6913 6 років тому

    Really impressed with your swimming Mark. However I couldn't help but notice your straight arm recovery stroke. Coming from swimming, I was taught all my life to swim a high ellbow - low hand recovery, yet in triathlon a lot of people seem to be swimming a straight arm recovery. Can you enlighten me on why this stroke is commonly used in triathlon?

    • @markthrelfall3577
      @markthrelfall3577 6 років тому +3

      Jonathan Hacker I need to do a video on this. It’s not something I taught myself, more it just happened over time. I used to have a lovely pool stroke. The straighter recovery is handy for getting in close to other swimmers to draft. Also, for making sure hands clear any waves or chop. I’ve also found that straighter arms helps a little for arm rate

    • @whittenmethod
      @whittenmethod 2 роки тому

      Gary Hall has an amazing book on details of stroke physics. The fast straight arm recovery increases of force the arm enters the water with and provides a coupling motion that increases the power of the pulling arm because it causes the shoulders to rotate more quickly.

  • @likemarksee
    @likemarksee 6 років тому

    Mark Threlfall, how does your CSS test result compare to your 1500m TT time? Which test result should be used for CSS swim sets. Is it possible to swim CSS sets at a pace which is too hard?

  • @chocolatefairy1822
    @chocolatefairy1822 4 роки тому

    Although an explanation of CSS is really well done, you then give examples of doing swims with x amount of rest (at 10.45) which completely voids the whole point of establishing the CSS pace. You could do you 20x100 with 5 sec rest, 10 secs, 44 seconds....etc. You are supposed to set the rest based on the CSS test. Please can you comment on this?

    • @allisonscanlan4144
      @allisonscanlan4144 3 роки тому

      Yes especially for intervals swimming should be based on CSS or swimming just on a specific time. More relaxed swims could just be with rest

  • @glenngundermann2433
    @glenngundermann2433 6 років тому +2

    The calculations seem to be screwy. You swam 4:36 and 2:12 for the 400m and 200m respectively. This works out to 276 and 132 seconds. The calcs used 261.6 and 127.2 seconds. Strange. You calculated 1.49 m / sec, which works out as CSS = 1.12 min / 100m or 1:07 / 100m. Your final verbal answer though was CSS = 1:12 / 100m, which is the correct answer had you used the correct number of seconds. 200 ÷ 144 = 1.39 m / sec, which arrives at CSS = 1:12 / 100m.

    • @dermotmarronify
      @dermotmarronify 4 роки тому

      He over-complicated it. Easiest way to do it is subtract the 200 time from the 400 time and divide by 2: (4.36 - 2:.2)/2 = 2.24/2 = 1.12

  • @akdrn3624
    @akdrn3624 6 років тому +2

    During recent races I was able to sustain a 1:43/1:45 pace for around 2000m (wetsuit open water at sea), while in the pool I wouldn't be able to use this pace for a 10x100 with short rest. I am more around 1:55. Earlier in the season I struggled to swim 2:10 in open water with a wetsuit and my pool times were pretty similar to the actual ones 🤔

    What about being an ok swimmer but having terrible turns affecting your pace for all the distances? I dont tumble turn so i am slow and dont push off particularly aggressively. Is there a way other than open water swimming that could account for it?

    • @markthrelfall3577
      @markthrelfall3577 6 років тому +1

      Joey C yeah, that’s an interesting one. But I think that would be shown by a slightly slower 400 to 200 relatively, due to there being more turns. I imagine it would come out with a CSS score in the right ball park that would project well to the longer distances. Give it a go, and let me know what you think

    • @joeyc8546
      @joeyc8546 6 років тому

      Mark Threlfall i get what you mean now. So the difference between the two distances almost takes account of the turns, so as long as they are consistent then it cancels them out, and the curve will be correct for drop off for the different distances. Thank you for replying! The video was excellent too, good to see the test in action and the results explained.

  • @diogoalmeida8211
    @diogoalmeida8211 6 років тому +2

    So, most AG triathletes that don't come from a swim background swim at above 2'/100m. They can manage a top speed of 1:50 on a 100m. Probably a 1:40/100 on 25's (numbers just average and for arguments sake). So, mostly Athlete B.
    I think they should work on getting to the top speed from 1:50 to 1:40/45 first, on the 100, ahead of thinking of working their Threshold pace from 2' to 1:55.
    I really believe they need to work on the top speed first (short, hard efforts with lots of rest), then threshold, then again the top speed, and so on. You always need a little "room to work with" between top and endurance speeds... Unless you are at the top of your game like the Brownlees or the guys from the 10k swim marathons. Not too much, or you'll end up being athlete A... but a little. Find the balance.
    Having said that, Threshold sessions have been my main tool for the past 20 years. Absolutely love them. I specially love 1x800 @ 12' (aim 11:35) + 2x400 @ 6' (aim 5:45) + 4x200 @ 3' (aim 2:45) + 8x100 @ 1:30 (aim 1:22/24)... so that'll take you 48' of grinding no matter how fast you swim...

    • @JakobThusgaard
      @JakobThusgaard 5 років тому

      Hey Diego, I'm admittedly late to the party here. Just wondering: what's the point of working top speed if one can't maintain it?
      What if that top speeds wears off too soon and the threshold speed ends up being faster over the course of the full distance?

      Todd Holmes hi Todd. I normally recommend doing a CSS/Threshold swim once per week if you can. If you only swim a couple of times a week, then aim for at least once every other week. The idea is that as you progress, you can sustain the pace more easily over longer reps, so you just build that up with time. But it is a little more taxing, so we tend to allow a touch more recovery for the longer reps

    400 metres in 4:21.6... not bad Threlfall, not bad.

    So athlete C is just a faster athlete B?

    So, as athlete A I just need to reduce my max speed a little and I'll be a threshold superstar? Thanks, got it!

    Wow 1:12/100m. IMO the CSS test is flawed. Using the calculation, your CSS pace is the pace you maintained for the second 200m of the 400m. The flaw is, most people can’t maintain that for a 1500m, it’s not even close. So using CSS calc. pace, you’ll end up swimming anaerobic for the first few reps. and you won’t be able to maintain that pace for the subsequent reps. However, you’ll find threshold pace by the end of 20* 100m.

      Mark w I see what you’re saying, but the way the calculation works projects that time whilst factoring in the pace drop. It really has worked for myself and many athletes I know for calculating threshold pace. I hear your concerns though

      I don't understand you. It basically says that his pace drops from 1:06min/100m for 200 meters to 1:09/100 for 400 meters to 1:12/100 for threshold, which is supposed to be a longer distance. That sounds logical

    Love how Mark converts his times into seconds wrongly, then complicates things, does not explain how he converts m/sec into CSS, but the result is correct. "I enjoyed doing the maths here" 🤣🤣🤣

      Mark Threlfall not exactly, diesel engines are torque power houses. 1,2 ecoboost at my best maybe? 😁💪🚗🚵🏊🏃

    Your swimming makes me depressed, maybe just fake your times for moral sake? :)

      Robin V 😛 I lived and breathed swimming from a very young age. It’s all relative, so just do the best you can. Let me know how you do
