I did a lengthy warmup, then 3 uphill kilos with a ride down the hill as a rest, then rested for about 5 minutes and did 5 uphill 200m sprints standing the entire way; then a nice cool down.

During the first sprint, a cow -- let's call her Jill -- in a pasture next to the road noticed me while drinking from a water source. When I came down the hill, the cow kept looking. By the third sprint, all the other cows had joined Jill in watching me. By the fourth sprint they were all up against the barbed wire looking my way. I kept moving forward after the fifth sprint as I sensed it was close to dinner time. These cows were definitely friendlier than the cows on the farm that we are renting; although, if I went up to the fence, they probably would have backed off a bit or bolted.
