Corola? Are you trying to avoid trade-mark infringement? :-)

For instance:

; WITH CTE AS (
    SELECT R.Name, H.Namn AS Horsname, 
           COUNT(*) OVER(PARTITION BY R.SocNr) AS cnt
    FROM   Rider R
    JOIN   Horse H ON H.RiderID = R.SocNr
)
SELECT Name, Horsename
FROM   CTE
WHERE  cnt >= 2
