Not sure how to log exercise

I can figure out how to log my exercise but it is the exercise (if it is exercise) that I did that I am not sure of where to put it. For the past week I have had to fill in for my dad in feeding our farm animals. So here is my basic run down on what I do.

1. Throw a hay bale down to lower barn.
2. One scoop of grain from storage room to first cow, and tie her in.
3. Back to storage room.
4. Fill bucket with corn cobs for both cows and pigs. Lock in second cow.
5. Take corn cobs to first cow, corn cobs to second cow, and corn cobs to pigs.
6. Return to storage room.
7. Grain to second cow.
8. Clean up patties from cows.
9. Storage room for sileage.
10. Fill bucket with sileage for first cow.
11. Back to room for more sileage.
12. Fill bucket with sileage for second cow.
13. Remove old hay from manger. And fill with hay that was thrown down.
14. Fill water bucket for pigs.
15. Take pigs their water.
16. Untie first cow. And unlock second cow.

I then drive to a second barn to take care of the horse.
1. Bring horses into their stalls.
2. Fill grain buckets from storage room and take to the stalls.
3. Fill water buckets in the stalls.
4. Take hay bales out into pasture.
5. Once horses are down with grain, let them out for the night.

So there really isn't any cardo or strength with weights. Just a lot of walking back and forth. I do this 2x a day.
