I did last night! After my TKB workout, I found an empty treadmill. Of course, it took me a few minutes to get my heart rate down to a normal range (those burpees in this TKB round are challenging).
But in straight-up LTD style, I didn't pay attention to the rules (who reads the instruction packet anyway?) I didn't realize the podcast was for 30mins and instead set my treadmill time to 20mins. I did manage to get in 6 runs and was interrupted by my TKB instructor. That's a great interruption!
So Saturday, I will do Wk1 Day 2 and Sunday will be Wk1 Day 3!!!
