Mathlete is usually used to refer to someone very dedicated to the math team of a primary school or secondary school. More specifically, a mathlete is to the math team as an athlete is to a sports team. This word is especially ironic because stereotypically, those who do well in math team tend to be diametrically opposite to real athletes.
You love math, be a mathlete!
