On the Concept 2: 

2 min, 3 min, 4 min, 5 min, 4 min, 3 min, 2 min pyramid / 2 min easy

Pre-set the monitor for 35 minutes. Row seven intervals in a pyramid of 2-3-4-5-4-3-2 minutes, with two minutes of rest in between each piece.

Messed up the setup of the monitor and did not input the first four-minute interval.  With the two minutes of rest between, I wanted to push myself a bit here and keep a moderate-to-hard pace each interval.
