I agree with Candice Zhou solution, you can use nested gridview or other data control like listview, datalist etc
First populate parent control with competition
SELECT DISTINCT COMPETITION FROM YOURTABLENAME
then populate child grid by this query.
SELECT * FROM YOURTABLENAME WHERE COMPETITION = @COMPETiTION
