Weather: light wind from the west, this slowed down the second and fourth sets a bit.

Plan:

• 4 sets of 5 x 2′ / 1′ rest
• each set would cover the length of the river.
• 4′ rest between sets
• pace: < 2:15
• rate: 26

Here’s the plots from the TCX data.

And the plot from the speedcoach.

Even allowing for the speecoach miscalibration, this was about a second slower than I would have liked.  But it was darn good training.
