Track & stairs

I ran with my son again today. He was off from school, so he was with me all day and then after work we just went to the track. He really struggles on the track, pretty much stopping 3-4 times per mile. When we go on the road he's nothing like that. 1 mile in he had to use the bathroom so we ran back to the gym. I ran stairs while he did his thing. That felt pretty good. I was winded near the end, but my legs felt fresh.
We both finished with a half mile on the treadmill...
