I thought that today's session had gone well in that I managed to do 15 of 16 fast lengths at a pace better than 2:00min/100m. My best lengths were at 1:47min/100m which isn't quite as good as last week but the difference is around 1 second per length which is probably within my error in stopping and starting the timer. I should have managed the 16th length at target pace but I set off thinking I'd try 2 or 3 lengths and I suspect that I reduced my commitment to the first one of the three and thereby failed on all counts!
I did achieve a stroke rate of 35spm within the session and there is a slight tendency for strokes per length to be reducing. Together I feel these number imply that I'm starting to get more power and by keeping distance covered in each stroke the length pace is improving.
As a note to self though, for Week 5 of the programme I should have done sets of 5 pairs of lengths. It makes sense to add more intervals to maintain the training intensity.
