how would you log this exercise?

GeminiDelight

i walk my kids to and from school. there are options in the list for walking, hiking and pushing a stroller. the thing is, the calories they say i am burning doesnt sound right. i know i can make a new exercise but i am unsure how many calories i am burning.

let me tell you what i do and maybe you all can help me figure out how to log this.

to school one way is .7 mi. it takes me 25 to 30 min to get there.

on the way there i have 3 kids in a stroller. 25lb, 30lb, and 40 lb. the first half is down hill, the second half is flat. the way back i have just the first 2.

in the afternoon it is the opposite. and the way back is half flat, half uphill with the 3 kids. the way there with the 2 kids. (the 40 lb kid goes to school).

i know i am doing more work than what the app says i am. i just dont know how to figure it. and i want to be accurate. i am breastfeeding and dont want to go into starvation mode. it would cause issues.

any ideas?
