I don’t have a lot of advice on how to swim faster, but I did want to point at your swim progression. Remember that progress is hardly ever linear; huge gains usually occur at the beginning, usually followed by a plateau and then alternating plateaus and incremental improvements.
1500m times
2016: 50 mins (OW, maybe long)
2017: didn’t swim much
2018, may: 35 min (pool)
2018, oct: 32 min (pool, ~10% improvement!!!)
2019 spring: 31 min (pool, still improving!)
2019 summer: plateau
2020 spring: 29 min (pool, improving again!)
2020 summer: didn’t swim
It will take some time to come back from the months out of the water. I’m been swimming since June and still not back to where I was after the 3 months off of swimming, so don’t be discouraged about not being immediatly back to where you were this spring.
Over 2 years (2018 spring to 2020 spring), you’ve reduced your 1500m time by 6 minutes (almost 20%)! That’s huge for us AO swimmers and you’re likely at a point where your gains are going to be incremental steps and not huge leaps. As others have suggested, maybe it’s time to try some additional speed work for a while and see what happens. Often times you just need a change in training stimulus.
I agree. Overall there has been progress. There have been interruptions which will throw off steady/consistent progress. These interruptions can kill progress/momentum. I was in the best swim shape of my adult life last March. Pools got closed for 3 months. I was good about doing dryland exercises, but it only helped mitigate the loss of swim fitness. I was back in the pool the end of May and have been working hard ever since then to get back to where I was. Despite higher frequency and slightly more volume, I’m still not back. Part of that could be that I’m battlling age (54yo), but I refuse to believe that so far.
To the OP, as others have said, really long, slow swimming isn’t going to help you get faster. My gains in the pool have come when I have cut out/reduced long continuous swims and have focused on sets of 100’s, 200’s up to 400’s. The guy who broke the Hawaiian Ironman swim course record a couple of years ago did it by training sets of 400 repeats. I asked a FOP swimmer what his swim training looks like and he said he does no sets longer than 400. Keep working! You’ll get there! Focus on shorter, harder sets. Good luck!
I’ll focus on speed work in the coming half a year. It really worked in the past 2019 - 2020 winter and I estimated that I dropped about 4 seconds per 100 over 2 months.
What I did was a USRPT set with the following simple rules:
- set a target time and try to make 30 x 100 m of it.
- the send off time is 20 seconds more than target time
- if I can’t meet the target time according to the pace clock, skip an interval
- 3 failures or 2 consecutive failures end the workout
- if I reach the end without 3 failures, next time I drop my interval by 2 seconds
- the first 5 intervals are the warm up - missing the time in the first 5 intervals doesn’t count as failures
I started this rigid plan 17 December 2019, initially I tried 1’48" target (short course) and made it with 2 failures. The next time I tried 1’46" target and made it with 1 failure only. Then I progressed to 1’44" target, I tried a few times and only made it with 2 failures in my 4th session at this target. Then COVID came and pool closed.
In March the long course pool was once reopened for a short while, I tried 1’46" and it was too hard - I accumulated 3 failures only at the 12th interval, then the world was shut again.
This month I restarted at 1’50" target long course and made it with 1 failure in my 2nd session trying this, I will try 1’48" in the coming week.
Unfortunately one of the two university pools (which are unheated outdoor pools) I had used for years is demolished and the other is closed for annual maintenance for about 6 - 8 weeks in winter. In the past one kept open while the other was in maintenance. I still can’t think of a way how to maintain that speed training at the beach yet. (I avoid municipal pools because they are heated to 26°C - 28°C; anything over 24°C degree is uncomfortable for me to do such speed training - I prefer 16 - 20°C pools)
