I lost some data today but I could still work out that I managed sub 2:00min/100m for 18 of the 20 sprint lengths. I suspect that I was faster on one of those too, but fumble my watch. Overall though that's not as good as last week's beginning but as i undertrained last week that wouldn't have helped.
At the end of last week I did a cut-short Week 7 Session 3 swim. That wasn't great either. Even though I did only 5 of 10 'fast' 100m sets I surpassed 2:00min/100 on just 3 of them.
Really this work on going a bit faster is proving hard work and with slight gains so far.
