Perhaps it wasn't a a good idea to do my week's worth of 3 sessions on consecutive days but at least I can say I've experienced some physiological overloading of my arms!
The session got off to a bad start with the warm-up just over 5:30 minutes but I managed to complete the task! I was even able to achieve success in the alternate 66m fast/slow sets until the lane became congested. By then it was nearly time to go anyway! All of the pacing was slower than in week 6, presumably due to the density of the sessions this week, but even so I achieved a pace of 2:10min/100m for 2 of the 66m sections.
