Biking (Commute) 20:00 [1] 9.92 km (29.8 kph)
For purposes of standardization, I think I'm going to set my commute to a speed of 2 min/km. In practice, I spend a bit more time in traffic, but it's simple to define the amount of "workout" I get as 2 min/km of distance. Hitting traffic lights on my bike might make the workout more interval-y, because I try to accelerate hard out of stops.
Today's morning commute was via Annette, Dundas, and College st. My peak speed was 36 kph with cruising speeds of 30+ kph.
