That was one hard swim set.
Seriously hard. Hardest set I've done to date. And I missed out 8 of the 100s 'cause it was proving a bit much. I think I was doing 1:41 100s a few times, which is mental for me, but I wasn't really paying attention that well other than the time I had before I had to start up again. Max heart rate 186!
Absolutely shattered after that and devoured a big lamb steak and puréed cauliflower for dinner. Inhaled it in minutes.
