I just struggled through Day 2 of Week 3:
27, 19, 19, 15, 25, separated by 90-second rests.
Except on 90 seconds I was only able to do 17 for Set 2, so for the next one I rested 2 minutes; barely cranked out the 19 so after that I rested 3 minutes. The 15 were hard but not impossible. I rested 4 minutes before the 25, which were j-u-s-t b-a-r-e-l-y d-o-a-b-l-e. Just barely.
Day 3 calls for 30, 22, 22, 20, 27.
Ack. I'm thinking I might have to repeat Day 2, or drop back from Level 3 (the most advanced) to Level 2 (intermediate.) Level 2's Day 3 is the same as the one I did today. I might have to stay at Level 2. This is getting really hard.
On the Achilles front:
Turns out that on the right it's not just tendonitis, it's actually a small tear, which will take longer to heal although the treatment is the same. I've been allowed to bike 10 miles but even that is causing a little aching and burning so I'm down to swimming, pool-running (great, I'm not crazy about swimming, it's the part of the triathlon I do as a required formality; pool-running has to be about as exciting as watching cows chew cud) and strength-training. I've got my pushups. And PT, where I do foot/ankle/leg/hip strengthening.
