13000 miles are 2092km and 147 metres.
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.
