Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
Nicki spent the last year running a lot. For the first half of the year, she ran a total of 20 miles per week. For the second half of the year, she increased the mileage to 30 miles per week. How many miles total did she run for the year?

### Response:
Each half of the year consists of 52 / 2 = <<52/2=26>>26 weeks.
For the first half of the year, Nicki ran 26 * 20 = <<26*20=520>>520 miles.
For the second half of the year, Nicki ran 26 * 30 = <<26*30=780>>780 miles.
For the entire year, Nicki ran 520 + 780 = <<520+780=1300>>1,300 miles.
