Finding the interval finder in GC very helpful in looking at anaerobic work, using W' to search.
This training block I have been doing the SubLT-W6 workout from TARPM once a week. After a 3 min VO2 interval, there is a 20 min interval of SST with 7x 10s jumps. After this, up to 6x 300m sprints (5m recovery). First week through, I got in 1x 300m sprint, almost lost my cookies, and called it a day. Last week I completed the full workout. Last night I just about lost my cookies after the 3rd 300m sprint, pulled the plug.
It was still some good training stress and practice going into the red and recovering at speed (unsurprisingly a weakness), as well as punching out a sprint with tired legs (also something that needs work), but still a bit discouraging. That is, until I noticed that the % of W' expended was much higher last night, even though last week I did 3 more sprints. Used the interval finder by W', sure enough, every jump was 0.5 to 1 Kj higher. Nice.
