I am 64 years old, 5'6", weigh about 142 lbs, and am of a slim build. I've also very fit aerobically, with a resting HR of 52.
I'd like to improve my times, which on my last 2K test were 2:12/2:27/2:27/2:19 for a total of 9:39 min. I ended up with an average stroke rate of 28 with splits rates of 27, 28, 29, and 30 respectively. I had to increase the stroke rates to get the same watts as my legs tired.
The trouble is, my average watts were only at 115. Watts on the splits were 128/109/110/113. I found I had to increase my stroke rate to keep the watts even somewhat consistent. Also, I did this test without any warm-up. According to my fitness tracker and my own impression, even with an average SR of 28, I never reached an anaerobic state during this test.
All this suggests to me that I have significant room for improvement but I'm not sure how to get there. I just seem to have no ability to increase my watts or to get to an anaerobic state except at very high stroke rates of 30 and above. This conflicts with what I've been told - to train at and aim for an average stroke rate of 28 SPR at the most. I know my skinny, narrow feet with high arches don't help any, but I can't change that

Any ideas as to how I can train to maximize my 2K watts and performance would be most welcome!
