I think you are a little confused.
If a race is 13k then the distance is 13 kilometres, obviously.
There is no such thing as a 13k marathon.
A marathon is 26.2 miles, or 42.2km - with a half-marathon being half that distance, obviously.
So, there is a chance that your 13km marathon refers to the 13.1 miles that are in a half-marathon.
Hope that helps.

13k typically refers to $13,000. In numerical terms, it is written as 13,000. This amount can also be represented in other currencies, but without specific context, it generally denotes the value in US dollars.
It is every 13K miles.
