Two 3.6-mile city rides. Possibly I had the wind at my bike, but I zoomed on the homeward leg.
2000 meters. I need to track my time, too. I know I can swim a kilometer in 20', but I don't know how long I can sustain that pace.
Before Gym Foofy, when I swam in city pools, it was rare for me to log two kilometers in a 50' period: the difference being not having to share a lane with four or five other people.
